• Windows 7 Won't Boot

  - by Vie

  I recently built a new computer, my fifth one. ASUS Maximus III Formula LGA 1156 Intel P55 ATX Motherboard EVGA 01G-P3-1452-TR GeForce GTS 450 Superclocked 1GB 128-bit GDDR5 PCI Express 2.0 x16 HDCP Video Card COOLMAX RM-1000B 1000W ATX psu Intel Core i7-875K lynnfield 2.93GHz LGA 1156 95w Quad-Core unlocked processor G.SKILL Ripjaws Series 16 (4x4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) memory WD VelociRaptor WD3000GLFS 300gb 10000 RPM SATA 3.0Gb/s Hard Drive Sony Optiarc CD/DVD Burner model AD-7261S-0B LightScribe Windows 7 Home Premium 64-bit It gets hung up on the starting windows screen. When I went to install the OS it did the same thing wouldn't go past the windows logo, so I put the new HDD into my old computer and installed windows 7 thinking it was just an installer error. Put the fully installed HDD back into my new machine and it still gets stuck on the starting windows screen. I've tried most everything I've looked up. Disabled USB, Disabled Turbo Boost, Disabled everything that wasn't essential(just about every configuration I can think of), took it apart and put it back together, took all the ram out save one 4g stick(wouldn't even boot when I did this), did a memory scan which came back successful, I don't know what could be wrong. Only thing I can think of is a compatibility issue somewhere, but I've ran over it again and again and I don't know where there would be an issue like that. Need Backup! .<

• Command line scripts to restore the 4 system databases of MS SQL Server 2008

  - by ciscokid

  Hi there, can someone give me some advice on how to restore the 4 system databases (master, msdb, model, tempdb) of a sql server 2008 please? I've already done some testing myself (on restoring the master database) with the following commad line script as a result: ::set variables set dbname=master set dbdirectory=C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA title Restoring %dbname% database net stop mssqlserver cd C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Binn sqlservr -m sqlcmd -Slocalhost -E -Q "restore database master from disk='c:\master.bak' WITH REPLACE" net start mssqlserver pause After the execution of the 'sqlservr -m' command (used to start the server instance in single-user mode, which is only necessary when restoring the MASTER database), the script stops. So in order to execute the last 2 commands I need to separate the script into 2 smaller scripts, and run them one after the other. Does anyone has an idea on how I can merge them into one single script that runs completely without any interruption? I also want to restore the other 3 system databases using command line scripts like this one. Can someone please advice me how I need to go on? I've already noticed that restoring the temdb is not so easy, but there has to be a way... Looking forward to your advice!

• Windows 7 64 bit Installation freezes after a while durig the setup

  - by vinz243

  I have a windows 7 32 bits on my computer. Because i have 5 gb of ram (kingston) on my asus M2N motherboard and only 3 were able to be used, I bought W7 x64 and install it. It loads the wizard, but after a while, it freezes, and I have to force reboot. It first crashed while unzipping w7 files, but if I wait a while on the terms page for example, it can crash before, which make me think that it is a matter of time. I remember I had the same issue while booting on Ubuntu x64, it crashed randomly but not load completely. No bip or other messages. Configuration: Software OS (before) W7 x86 Pro New OS : W7 x64 Pro Antivirus : avast (bios verification ?) BIOS 03/27/2008 - v08.00.12 Hardware : Motherboard : Asus M2N Processor : AMD Athlon 64 dualcore @ 2.6 GHZ Memory : 5120 MB ((2 + 2) + (1)) NOTES : I ran a memory test using openSUSE cd, though i have not finished it, it ran. EDIT: I tried not to run the setup but wait, and i get the BSOD : A problem... TL;DW IRQL_NOT_LESS_OR_EQUAL If it is.. TL;DW ***STOP: 0x0000000A (0x0000000000000000,0x0000000000000002, 0x0000000000000001, 0xFFFFF8001A49ED1F)

• What to do when a device has no driver for Windows 7 but it has Vista, XP drivers

  - by Mehper C. Palavuzlar

  This has always been a bothersome matter for me. Some devices (printers, scanners, etc.) have drivers for older versions of Windows (Vista, XP, 2000, NT) but no driver for Windows 7. What are my chances to install such devices on Windows 7? Example case: I have a Sharp printer & scanner (Sharp AR-122E N) which I have used for my old Windows XP based PC. Now I want to install it on a Windows 7 x64 based PC. Windows 7 cannot load its driver. I used the original driver CD but when I run the setup.exe (which is included in AR122EN111.exe, 6713KB), it says Cannot install driver on this operating system. Supported operating systems are: Windows 2000, XP, Vista. I tried to install the driver using compatibility settings. I tried Windows Vista and Windows XP SP3, but to no avail. The setup gave the same error. I also googled for Windows 7 driver for "Sharp AR-122E N" but it only listed the original driver that I tried. The official site of Sharp does not even list the driver for this product. In the past, the compatibility setting workaround did work for some devices, but this time it failed. What else can I do to overcome this problem?

  - by BanKtsu

  Hi I just wanna disable the default RAID in my server IBM System X3400 M2 Server(7837-24X),i have 3 disk drives SAS. I want to make them a JBOD "Just a Bunch Of Disks", because I want to install in the drive 0 CentOS, and the other two make them cache files for a squid server. I disable the RAID in the BIOS: System Settings/Adapters and UEFI drivers/LSI Logic Fusion MPT SAS Driver -PciRoot(0x0)/Pci(0x3,0X0)/Pci(0x0,0x0) LSI Logic MPT Setup Utility RAID Properties/Delete Array Later I boot the CentOS live CD and install the OS in the drive 0, and the others 2 mounted like this: *LVM Volume Groups vg_proxyserver 139508 lv_root 51200 / ext4 lv_home 84276 /home ext4 lv_swap 4032 Hard Drive sdb(/dev/sdb) free 140011 sdc(/dev/sdc) free 140011 sdd(/dev/sdd) sdd1 500 /boot ext4 sdd2 139512 vg_proxyserver physical volume(LVM) But when I restart the server give me the error: Boot failed Hard Disk 0 UEFI PXE PciRoot(0x0)/Pci(0x1,0X0)/Pci(0x0,0x0)/MAC(001A64B15130,0X0)) ........PXE-E18:Server response timeout.

• When machine is turned on, only the fan runs

  - by Gopal

  Hi, I have an issue slightly similar to this one posted here, http://superuser.com/questions/127016/troubleshooting-monitor-never-turns-on-system-fans-running-dvd-rom-does-not-op My configuration is as follows: EPOX 9NPA+ Ultra motherboard AMD Athlon 64 CPU Corsair 2 x 1GB PC3200 DDR RAM 1 DVD RW drive and 1 CD ROM Drive SATA 250 GB Hard drive 400W Power supply EVGA 256MB graphics card I have had this configuration for about four years. Last month, I started having issues in starting the machine. It wouldn't start when I press the ON button in the front of the case. So I used to pull out the power cord and plug it back in and then switch on in the front, and it used to work fine. And then one fine day, when I plugged in the power cord at the back, even without switching on the power-on button at the front, I saw that the fan at the back was running. So I opened the system. Then I could see that all the fans inside were running. I replaced the power supply. No luck there. Then I replaced the CMOS battery. Again nothing improved. Even when I removed all the cards and memory, I still get one short beep. That's it. Any idea how to proceed on this? Anything else could be checked? I want to confirm if this is a motherboard failure, before proceeding to replace it.

• How to install a desktop environment onto Ubuntu Server -- but without internet access or a CDROM?

  - by James

  I am playing around with a computer which has no CDROM drive or internet access and I have installed Ubuntu Server onto it. I have that all up and running nicely but now I'd like to install Xfce, GNOME or something similar so I can load up a desktop environment from the command line if I wish. Obviously with internet access or a CDROM, this would be a simple task of using apt-get and it finding & retrieving the packages for me, I assume, but I do not have either. I do however have a USB drive and I have used Unetbootin to make it into a bootable drive with the Ubuntu Server disk image files on there. I have mounted the USB drive to /media/usb0 and tried the command "sudo apt-cdrom add -d /media/usb0" to get apt to recognise the USb drive as an "Ubuntu CD" -- a source of package files but apt-get doesn't seem to be finding Xfce.. I try "sudo apt-get install xfce" and "sudo apt-get install xfce4" but neither find the package.. I would prefer to have Xfce but GNOME would be OK too.. My question is, am I doing something wrong? I figured that the Ubuntu Server disk (or rather, my Ubuntu Server USB drive) might not have any desktop environment packages on there so I tried the Xubuntu Desktop disk too (again, from my USB drive). I tried "sudo apt-get install xubuntu-desktop" but it couldn't find the package - even though it is listed under the /casper/ directory in some MANIFEST file. Anyone see where I'm going wrong? Maybe apt-get install is looking somewhere other than my USB drive? Maybe my commands are wrong? Maybe the disks don't even have the desktop environments on!? Thanks in advance guys, any input would be much appreciated. Cheers - James

• Interesting phenomenom with Windows Server 2008 R2 user access controls and NTFS ACLs

  - by Simon Catlin

  One to try, and I'd appreciate any thoughts on this. On a Windows Server 2008 R2 box (or presumably 2008 R1, Windows Vista or Windows 7): i) Logon as an administrator, and create a new NTFS volume ii) Blow away the standard MS ACLS on the root of the volume (which are laughable), and replace with Administrators:Full Control, System:Full Control, e.g.: echo Y|cacls.exe d:\ /g "Administrators:F" "SYSTEM:F" iii) Now, from a Command Prompt shell window or PowerShell window, switch to that drive (cd /d D:\ or set-location D:\ ). Works fine... no issues. iv) Now, try to browse to the root of the new volume using MS Explorer... Access denied. Now, I've kind of convinced myself that it is UAC getting in the way, as you can add "Authenticated Users:List" access to D:\ and Explorer then works. I can only assume that MS Explorer isn't able to use the "admin" token for the Administrator. Browsing to explorer.exe and doing a "Run as administrator" has no effect. Any thoughts? Cheers in advance.

• Cannot find wireless driver for HP laptop

  - by rodey

  I have an HP laptop (model: dv7-1267cl, Windows 7 64-bit Home Premium) and I cannot find the wireless driver for the laptop. I am need of a different version because my wireless connection under Windows is flaky and unreliable. I have problems printing to my wireless printer and logging in to and using several sites like reddit.com, phoenix.edu and facebook.com - I get several "page cannot be displayed" messages while using my wireless connection. I disable my wireless adapter and use an ethernet cable and it all works fine. I also used an Ubuntu Live CD to confirm that there is not a problem with the hardware. This is software/driver issue. The drivers were auto installed by the OS. The Device Manager shows the wireless adapter as Atheros AR5009 802.11 a/g/n WiFi Adapter. I have checked the HP website for my laptop and they do not have wireless drivers listed for that model wireless adapter. I have also checked with atheros.com and I do not see my model adapter on their list of available hardware. Device Manager lists the Hardware ID's for my adapter as: PCI\VEN_168C&DEV_002A&SUBSYS_1381103C&REV_01 PCI\VEN_168C&DEV_002A&SUBSYS_1381103C PCI\VEN_168C&DEV_002A&CC_028000 PCI\VEN_168C&DEV_002A&CC_0280 A search for the first Hardware ID turned up this question from experts-exchange.com. tl;dr A driver does not exist for that model adapter.

• Forward secrecy in Nginx (CentOS6)

  - by Anil

  I am trying to enable Forward secrecy in CentOS with nginx webserver. What I have tried I have read some tutorials and seems like we should have nginx, openssl latest versions to enable it. So I had installed the openssl latest from source. sudo wget http://www.openssl.org/source/openssl-1.0.1e.tar.gz sudo tar -xvzf openssl-1.0.1e.tar.gz cd openssl-1.0.1e sudo ./config --prefix=/usr/local sudo make sudo make install Now OpenSSL supports the Eliptic Curve ciphers(ECDHE). I tested this with openssl s_server also. It worked well. Next, I replaced Nginx with latest. sudo wget http://nginx.org/packages/centos/6/x86_64/RPMS/nginx-1.4.2-1.el6.ngx.x86_64.rpm sudo rpm -e nginx sudo rpm -ivh nginx-1.4.2-1.el6.ngx.x86_64.rpm and configured Nginx as described in this link ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_prefer_server_ciphers on; ssl_ciphers EECDH+ECDSA+AESGCM:EECDH+aRSA+AESGCM:EECDH+ECDSA+SHA256:EECDH+aRSA+RC4:EDH+aRSA:EECDH:RC4:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!SRP:!DSS; http://baudehlo.wordpress.com/2013/06/24/setting-up-perfect-forward-secrecy-for-nginx-or-stud/ But now Nginx does not support ECDHE ciphers. It supports DHE ciphers. I tried by just enabling ECDHE cipher in nginx still doesn't work. I am using latest web browser(chrome 29 and it support this cipher) Am i missing anything ? Or Having issues with CentOS or Nginx? I read somewhere that ECC patent issues with CentOS, is this causing problem?

• Windows 7 DVD doesn't boot up, neither does USB. :'(

  - by Manan Shah

  My problem is that i'm not able to install windows 7. Been trying to install this since past 1 week. The methods i've tried are: I have a windows 7 bootable DVD which doesnt boot up. (I've set BIOS to boot from DVD ROM first but it just won't boot from the DVD). Tried to install Windows 7 from the same DVD to a friend's PC and it worked. So the DVD has no issues. I tried to run 'Setup.exe' from within the DVD. The two options pop-up 'Check compatibility' and 'Install now'. On clicking install now, after sometime, an error is encountered with the message 'Windows was unable to create a required installation folder' error code:0x8007000D. I am running Windows XP Professional and there's only one user on the PC which is the Admin, so i do not know why is the setup not getting permissions. I've also uninstalled my antivirus, CD burning software, disabled firewall and disconnected all other devices, but its still the same. I tried to install it from a USB device by making it bootable but that too doesnt work. (Yes the mobo supports booting from the USB). The problem is that XP does not recognize a 'USB' device on boot. Rather it shows this USB stick as a removable 'Hard Drive'. Furthermore, i changed the order of Hard Drive boot to boot from this removable Hard Drive first, it still boots my existing OS. Is there anything else that can be done? Any help would be greatly appreciated. :) Please ask if any other information is required, this post is becomimg increasingly long to add any other details. PS: I want to dual boot windows 7 with my existing XP, but that would be after i manage to run the windows 7 setup in the first place. PPS: Please bare with any 'not-so-technical' terms, i am a beginner with this. Again, thank you for taking the time and trying to help, really appreciate it. :)

• Why might my Fedora 15 live USB persistent storage not work?

  - by Richard J Foster

  I created a Fedora 15 "live" USB stick using the live USB creator found at https://fedorahosted.org/liveusb-creator/ and the Fedora 15 i686 Desktop ISO image with the persistent storage space set to 4096MB. (The USB stick I have available has an 8GB capacity, so there should be plenty of space.) Fedora appears to boot correctly, however it seems that the persistent storage is not working. To verify this, I opened a terminal prompt, then did su - followed by yum update yum. As expected, I was informed that a new version was available. (The live CD contains version 3.2.29-4, at the time of typing 3.2.29-6 is the current version). After installing, I verified that the new version was installed by typing yum --version. I then shutdown the system using shutdown now. After the system had shut down, I rebooted and returned to the terminal prompt. On typing yum --version, I was informed that the version was 3.2.29-4 (i.e. the original version). Why might the persistent storage not be working? Is there anything I can do to fix it?

• KVM Guest Reboot Loop

  - by javano

  I have been pulled into a situation where a KVM server (CentOS 6.2) lost power and upon reboot one of the guests hasn't started up again (XP SP3). I have SSH'ed in and someone must have changed something relating to the hyper visors prior to the power loss, but not rebooted all the guests. This particular guest wouldn't start because it was configured to use /usr/bin/qemu-system-x86_64 which isn't there now (assuming it was before?). I changed it to use /usr/libexec/qemu-kvm as this is what all the other guests on this server seem to be using, and its booting up. Using virt-manager on my local machine I can connect to the display of the XP machine and it gets as far as this screen; http://support.gateway.com/emachines/issues/2-1131285152-01.gif The problem I face now, is that which ever option I choose the machine just reboots. So it's and endless loop. I thought that perhaps a file system error maybe present due to the unclean shutdown. There is an XP SP3 ISO mounted under the guest, which I booted from in an attempt to access the recovery tools, but I don't have the Administrator password! I am out of ideas, and it's turning out to be quite the conundrum. Should I use a 3rd party live CD to test the FS for errors? How else can I trouble shoot these restarts?

• Weirdly high ping on direct ethernet connection?

  - by Antriel

  I bought new Lenovo IdeaCentre H430 pc and I'm having problem with high pings. Windows 7 with on-board realtek NIC. Fresh install, fully updated, drivers installed from included CD. When I start pinging router (direct 1Gb ethernet connection, 1 hop), pings start at <1ms (which is fine) and after a while they jump to 300-1000ms. I loaded up live ubuntu to test if the problem might be in HW. It's not, in ubuntu pings were always <1ms. I also noticed that when I start using connection somehow, pings go down to 1ms, but go back up when I stop using it (tested by accessing live camera feed on LAN). Power Options set to max performance. I disabled Interrupt Moderation on the NIC, didn't help. I tested it in the safe mode with networking, same problem there. It slows down our client-server based programs and I have no idea what's causing it. All I could google up was that disabling Interrupt Moderation would help, it didn't though. Anyone had similar problems? tl;nr: Computer is giving high pings to router when idle and normal pings when network is under load, it slows down our software significantly.

• Computer Won't Boot Properly, unless in safe mode?

  - by Mr_CryptoPrime

  I bought a computer today and booted it up, but when I did I only got a blank screen. I checked to make sure it wasn't the monitor by connecting it to my old computer...it worked. I then tried connecting my monitor to both DVI ports and found that the bottom one did work. However, now it just boots up and says "loading windows" and then when the login screen is suppose to come up the screen just goes blank and monitor says "no input, check cord" (or something like that). I tried reinstalling windows and then I was able to log on normally. I used the CD's and reinstalled all the drivers, then rebooted...now I am stuck right back where I started. I tried taking out the RAM and inserting into different slots, that didn't fix anything. I was able to boot up into windows using safe-mode. I suspected that my ATI Radeon 6950 was the issue and downloaded the drivers, but I can't install them on safe-mode. Someone said to install C++ distr. and I tried doing that to fix driver installation problem of "failed to load detection driver" but it wouldn't let me do that either. Please someone help me, I don't want to have to deal with the evil redtape of sending it back to get a replacement!

• Power issues Foxconn Barebones kit

  - by alpha1

  I have a Foxconn R20D2 bought about a year and a half ago. It ran fine for a while and then around last summer it started having power issues. I chalked it up to changes in electric current due to the overwhelmed grid when people turn on their AC units, but this problem has stayed for all year, shutting off randomly, shutting off when i turn on a vacuum and similar problems. Now that its summer again, the box basically sits there all day cycling itself, and now has gotten to the point it tried to boot and after 3 seconds, fails, shuts off and tried again. I know its power related, it runs opensuse linux and there are never any shutdown logs or anything of that sort. As the weather got hotter i noticed it happening more and more, and it most often happened in the morning, i presume as people woke up and turn on the AC. The power supply is a Chennel well technology co LTD model DSL-150. 150W max output. Its an intel atom dual core, with 2 sata drives, no CD/floppy etc, recently upgrades from 2 to 4gb of ram. It runs at 104 degrees Fahrenheit all the time almost. Any way i can test the power supply or anything else to try to fix it? Im a software guy, not hardware so im at a complete loss here, thanks for all assistance you can provide! EDIT: The switch on the back that says 230 or 115 is set to 230. If im in the USA, could that be causing the problems?

• Windows 7 Startup fails after installation

  - by Nadav S.

  I have installed Windows 7 Ultimate a week ago. Yesterday I've noticed that the SP1 update is available. After installation of SP1 the computer failed to startup, and had shown a black screen. I couldn't even go to safe mode and F8 didn't help. After some fixing attempts including system restore, startup repair, bootmgr & BCD rebuilding from CMD, I have decided to reinstall Windows (after all, it's only a week old) After the successful installation, I have decided to first install all available updates before I continue. So after the updates download & installation, the computer rebooted. And now I didn't see the black screen again - but in the "Starting Windows..." screen the logo didn't appear and the system didn't startup. Here I could go to safe mode selection window, but it didn't work either ("Loading Windows Files" but nothing). I've also tried: I thought that the CD was corrupted, so I've used a fresh new disk of Windows, tried x86 & x64 versions, the same symptoms, no change. Resetted the BIOS to default, no change. Memory diagnostic HDD diagnostic Restarted Windows WITHOUT INSTALLING UPDATES, but it had the same symptom, so maybe Windows Update is not the case?! I've tried installing it so many times - that I am simply stuck - I can't "reinstall Windows, because it is corrupted...". Maybe the HDD is corrupted? I've also checked it and didn't find a problem.

• File permission woes on an Ubuntu ec2 instance

  - by Pardoner

  I've set up an amazon ec2 instance and I'm have some file permission issues. I've created myself a new user and added myself to the following groups: adm:x:4:me,ubuntu sudo:x:27:me www-data:x:33:me,www-data ssh:x:108:me admin:x:111:me ubuntu:x:1000:www-data,me me:x:1001:me but when I cd /var/www I can't do simple commands without doing sudo. So I chown -R www-data:www-data /var/www to ensure that I'm in the owning group but I still have to type sudo for everything. If I sudo su www-data it works fine. Since I'm in the www-data group shouldn't I have the same privilages as www-data? One strange thing I'm noticing is that when I ls -l it list the owner but not the group names. Could this possibly be part of the issue? Is is posible for a directory to not be part of a group? drwxr-xr-x 4 www-data 4.0K Oct 24 16:39 . drwxr-xr-x 14 root 4.0K Oct 10 16:58 .. drwxrwxr-x 9 www-data 4.0K Oct 23 04:03 admin.mywebsite.com drwxrwxr-x 2 www-data 4.0K Oct 4 00:29 mywebsite.com drwxrwxr-x 9 www-data 4.0K Oct 23 04:03 staging.mywebsite.com Edit : It appears I had some alias messing with my ls command. By calling \ls -l I can see that all my files are in the correct group.

• HP DL185 - very slow disk read speed

  - by fistameeny

  Hi, I have a HP DL185 G6 Server (12 disk model) with the following spec: Quad Core Xeon 2.27GHz 6GB RAM HP P212 RAID controller with battery backup 2 x 128GB 15K SAS 3.5" (RAID-1 for the operating system) 4 x 750GB 7.5K SAS 3.5" (RAID-5 for the data, 2TB usable space) The operating system is Ubuntu Server 9.10. Both drives have been formatted as EXT4. We are finding that read speed of the RAID-5 array is poor. Disk test results below: sudo hdparm -tT /dev/cciss/c0d1p1 /dev/cciss/c0d1p1: Timing cached reads: 15284 MB in 2.00 seconds = 7650.18 MB/sec Timing buffered disk reads: 74 MB in 3.02 seconds = 24.53 MB/sec For info, the RAID-1 array performs as follows: sudo hdparm -tT /dev/cciss/c0d0p1 /dev/cciss/c0d0p1: Timing cached reads: 15652 MB in 2.00 seconds = 7834.26 MB/sec Timing buffered disk reads: 492 MB in 3.01 seconds = 163.46 MB/sec We thought this was because with no battery, read/write cache is disabled. We have bought and installed the battery backup and have used the HP bootable CD to change the cache settings to 50% read / 50% write and check cache is enabled on the drives and the controller. Is there something I'm missing?

• How to avoid sshfs freezing?

  - by Andreas Hagen

  So the issue is this: I've installed sshfs on Ubuntu 12.04 and I'm trying to connect to a couple of remote servers. So initially the mount seams successful. Sometimes Gnome even picks it up and displays the "new device found" box at the bottom of the screen. but from here on there is not much that works. Or at least not any more. The first couple of times i connected it seamed to work fine, and I was able to transfer some files, then i disconnected using fusermount -u <folder> and after reconnecting a little later the trouble started. Now after executing sshfs -o ServerAliveInterval=15 -o reconnect -C -o workaround=all -o idmap=user root@<host>:/ <folder>, when I change directory into the mount-point, the shell just freezes. Strangely ls -al <folder> works when listing just the root of the remote system, but nothing more. Also every file-explorer I've tried freezes just like cd <folder>. To me it seamed like there was some kind of zombie thread or something hanging around my system, due to the fact that it did work the first time, so I have tried rebooting but no luck. sshfs -V gives this: SSHFS version 2.3 FUSE library version: 2.8.6 fusermount version: 2.8.6 using FUSE kernel interface version 7.12 So yea, any ideas?

• Ubuntu 12.10 64bit host reboots when trying to install any guest system using VirtualBox

  - by gts123

  I am having a really nasty problem with VirtualBox as everytime I try to install any guest OS(using ISO file as CD for installation media), the installation starts normally but as soon as it is about to start either installing to virtual hard drive or loading(e.g. as LiveFS) it causes the host system to reboot abruptly. Config is as below: Host system: Ubuntu 12.10 64bit - Intel® Core i7-2640M CPU @ 2.80GHz × 4 Virtualbox version: 4.1.18_Ubuntu r78361 Guest OS systems tried: 32bit version of FreeBSD 9, Debian 6, Tails 0.14 VM setup Tried to have the minimal setup necessary just in case it would avoid for each system to make sure I'd avoid conflicts, but to no avail. I've tried different values and combinations of the below but the problem still persists: Shared Clipboard: Disabled Show in fullscreen/seamless: Disabled Remember runtime changes: DIsabled Base Memory: 2048 MB Chipset: PIIX3 IO APIC: Disabled EFI: Disabled Absolute Pointing device: Disabled Processor(s): 1 CPU PAE/NX: Disabled VT-x/AMD-V: Disabled Video Memory: 12 MB 3d/2d acceleration: Disabled Storage IDE COntroller: PIIX3 (same as chipset instead of PIIX4) Use host I/O cache: No Audio: disabled Network adapter: NAT USB controller: disabled No shared folder Also another sideeffect of the reboot is that it appears that it does not log any information in the error log files; not making things any easier. Please help.

• Installing Ubuntu guest crashes Hyper-V host

  - by Grant

  I have a weird problem that I don't even know where to begin diagnosing. Trying to install Ubuntu to a VM locks up the host system! My setup is: Dell R715 server, dual 16 core AMD opteron processors, 96GB RAM Dell MD3600f SAN Server 2008 R2 Datacenter System Center VMM 2012 There are 5 windows virtual machines running that have had no problems. This is the first linux VM I've tried to create. I setup a VM through virtual machine manager, set the CD drive to a Ubuntu 12.04 server x64 iso, and started it up. It boots up the normal ubuntu install menu, but the second I hit enter on "Install Ubuntu Server", I get disconnected. The HOST machine stops responding to pings. So do all virtual machines on it. It locks up entirely - keyboard on the host won't work, mouse won't move, numlock light won't change. There's no blue screen - the host is sitting at the login screen completely unresponsive. I can't find any relevant logs in event viewer after rebooting. What could cause the host machine to freeze like that? It's not a one time occurrence - it happens every time at the exact same point. Thank god this server isn't in production yet!

• Boot records messed on dual boot (win7 and ubuntu) machine with SSD and HDD

  - by Michael

  i have a lenovo ideapad y570 with two hard drives: SSD and normal HDD both managed by RapidDrive and windows 7 pre-installed. First, i have shrunk my 500 GB HDD a little bit to make some place for a linux installation. Then i installed linux mint 12 to it, also installed grub onto the drive (dev/sdb). Installation programm has not allowed me to install grub on sda. Then i replaced linux mint with ubuntu 12.04 but installed grub onto the SSD (which is dev/sda and was the default-option). After that i could boot into my windows, only ubuntu worked. So i did a research, and tried: rewriting mbr of windows into sda1, reinstalling grub, replacing grub2 with grub-legacy, and now i think my partitions table are totally messed. Here is fdisk -l output: ubuntu@ubuntu:~$ sudo fdisk -l Disk /dev/sda: 64.0 GB, 64023257088 bytes 255 heads, 63 sectors/track, 7783 cylinders, total 125045424 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sda1 * 2048 411647 204800 7 HPFS/NTFS/exFAT /dev/sda2 411648 1009430959 504509656 7 HPFS/NTFS/exFAT Disk /dev/sdb: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x5e5d1cc8 Device Boot Start End Blocks Id System /dev/sdb1 * 1979 884389887 442193954+ 12 Compaq diagnostics /dev/sdb2 884391934 976771071 46189569 5 Extended /dev/sdb5 884391936 937705471 26656768 83 Linux /dev/sdb6 937707520 967006207 14649344 83 Linux /dev/sdb7 967008256 976771071 4881408 82 Linux swap / Solaris I also cant mount any windows partitions to recover data. And when i open gparted, the whole sda-disk appears unallocated and it states "can not have a partition outside the disk!", also the end-sector address of /dev/sda2 confuses me. If i boot from the SSD, it throws some mbr error and wont boot, if i boot from the HDD, i only get the grub bash. How do i restore the partition tables? I can boot only from a live-cd at the machine. Thanks for any help.
