• Upgrading Ubuntu(32 bit) 10.10 -> 11.04 fails and causes a kernel panic on boot

  - by Ubuntu Upgrade

  On Ubuntu 10.10 machine Upgrade to Ubuntu 11.04 using the update manager. The upgrade fails and leaves the system in an unstable state. When I reboot the system I get a kernel panic on boot. The error points to /opt/abc/runtime/lib/libc.so.6. By researching on this I found that there is a third party software abc causes problem. It has it's own runtime(libc) library. In /lib/ directory there is a link file /lib/ld-abc.so.2 ---/opt/abc/runtime/lib/ld-linux.so.2. If we rename this file to /lib/abc.so.2 or remove this file the the upgrade is success. Here is the upgrade log of where it crashes(apt-term.log) ===== Services restarted successfully. Processing triggers for libc-bin ... ldconfig deferred processing now taking place /usr/bin/dpkg: /opt/abc/runtime/lib/libc.so.6: version `GLIBC_2.11' not found (required by /usr/bin/dpkg) /usr/bin/dpkg: /opt/abc/runtime/lib/libc.so.6: version `GLIBC_2.8' not found (required by /lib/libselinux.so.1) ===== Could you please let me know what would be the problem of having a run time link library file in /lib directory. Does the ubuntu upgrade check the 3rd part runtime as well?

• My new hard drive won't automount on boot

  - by user518

  I installed a new hard drive right before installing the new Ubuntu 11.10 by reformatting, not upgrading. I was able to mount my drive, and partition it. It's a 1TB, and I was able to transfer all of my music, and videos to it. For some reason, it won't mount on boot, and I can't figure out how to manually mount it afterwards either. Here's my current /etc/fstab: # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed.

• Used mountmanager now Ubuntu hangs on boot

  - by fpghost

  I was using MountManager in Ubuntu 12.04 to set user permissions in mounting hard drives. I set each partititon to be mountable by everyone instead of admin only. Then I clicked Apply in the file menu and it gave me the message successfully updated. Upon restarting Ubuntu, just hangs on the splash screen and does not boot any further. Windows still boots fine.

  - by user147220

  im running ubuntu 12.04 and it refuses to boot up. the screen will come on for a second, the mosue will appear, then itll go black again all inside about 3 seconds. i let it just do that for a while and eventually a window popped up saying i had a display issue. I didn't have a mouse but there was a button saying "ok" at the bottom that i couldnt click on. i hit enter, got through that screen, now im looking at another that says "What would you like to do?" - run in low-graphics mode for just one session - reconfigure graphics - troubleshoot the error - exit to console login then two buttons, cancel, and ok. I dont have a mouse and its not letting me navigate between these options with tab. firstly, if i make it through these windows will it get me into the computer so i can try and fix whats going on? also, whats going on here? also, how can i click on these buttons without the use of tab or a mouse?

• Booting the liveCD/USB in EFI mode fails on Samsung Tablet XE700T1A

  - by F.L.

  My tablet is Samsung Series 7 Slate (XE700T1A-A02FR (French Language)). It operates an Intel Sandy Bridge architecture. The main issue about this tablet is that it ships with an installed Windows 7 in (U)EFI mode (GPT partition table, etc.), so I'd like to get an EFI dual boot with Ubuntu. But it seems I can't boot on the liveCD in EFI mode. It starts loading (up to initrd), but I then get a blank (black) screen. I've tried the nomodeset kernel option (as well as removing quiet and splash) with no luck. [2012-09-27] I have used the Ubuntu 12.04.1 Desktop ISO (I have read somewhere that it is the only one that can boot in EFI mode). I'd say this has something to do with UEFI since the LiveCD boots in bios mode but not in efi mode. Besides, I am not sure my boot info will help, since I can't boot the LiveCD in EFI mode. As a result I can't install ubuntu in EFI mode. So it would be the boot info from the liveCD boot in bios mode. This happens on a ubuntu-12.04.1-desktop-amd64 iso used on a LiveUSB. Live USB was created by dd'ing the iso onto the full disk device (i.e. /dev/sdx no number) of the Flash drive. I have also tried copying the LiveCD files on a primary GPT partition, but with no luck, I just get the grub shell, no menu, no install option. [2012-09-28] I tried today a flash drive created with Ubuntu's Startup Disk Creator and the alternate 12.04.1 64 bit ISO. I get a grub menu in text mode (which meens it did start in efi mode) with install options / test options. But when I start any of these, I simply get a black screen (no cursor, neither mouse nor text-mode cursor). I tried removing the 'quiet' option and adding nomodeset and acpi=off, but it didn't do any good. So this is the same result as for the LiveCD. [2012-10-01] I have tried with a version of the secure remix version via usb-creator-gtk. The boot on the USB key has the same symptoms. Boot in EFI mode is impossible (I have menu but whatever entry I choose, I get the blank screen problem). The boot in BIOS mode works, I did the install. Then I used boot-repair to try installing grub-efi and get a system that would boot in efi mode. But I can't boot this system, because the EFI firmware doesn't seem to detect that sda contains a valid efi partition. Here is the resulting boot-info Boot info 1253554 [2012-10-01] Today, I have reinstalled the pre-shipped version of windows 7, and then installed ubuntu from a secure-remix iso dumped on USB flash drive vie usb-creator-gtk booted in BIOS mode. When install ended, I said "continue testing" then I used boot-repair to try get the bootloader installed. Now, when I boot the tablet, I get the grub menu, it can chainload windows 7 flawlessly. But when I try to start one of the ubuntu options I get the same old blank screen. Here is the new boot-info: Boot info 1253927 [2012-10-01] I tried installing the 3.3 kernel by chrooting a live usb boot (secure remix again) into the installed system. Same symptoms. I feel the key to this is that the device's efi firmware (which is EFI v2.0) would expose the graphics hardware in a way that prevents the kernel to initialize it, and thus prevents it from booting (the kernel stops all drive access just after the screen turns kind of very dark purple). Here is some info on the UEFI firmware as given by rEFInd: EFI revision: 2.00 Platform: x86_64 (64 bit) Firmware: American Megatrends 4.635 Screen Output: Graphics Output (UEFI), 800x600 [2012-10-08] This week end I tried loading the kernel with elilo. Eventhough I didn't have more luck on booting the kernel, elilo gives more info when loading the kernel. I think the next step is trying to load a kernel with EFI stub directly.

• Install Linux Mint on PC without bootable CD

  - by crosenblum

  Unfortunately my PC's CD drive is not bootable; I have such a mixture of SATA and IDE drives, so until I have more money to redo my controller setup, I can't boot from any cd. Currently, I have a DVD burned with latest version of Linux Mint, and I have an USB drive with an old version of Mint. I have a partition ready to install Linx Mint into, but no idea how to install it, since I can only boot to my hard drive. I am totally unable to boot to CD, so that is definitely out. My main partition is WinXP Pro SP3. Is there software I can use to format my Linux partition, so that I can then just copy Mint over to that partition? Or is there a better way to install linux mint? I have to do it within Windows XP, since that's all that I can boot right now. I have considered Mint4Win, but that doesn't allow a full installation of Linux Mint. Any ideas?

• Linux Uninstalling errors

  - by Zack

  I want to uninstall back-track 5 so I deleted the partitions for back-track os. After deleting the partition that used to be for back-track becomes free space as in picture. But I can't delete that partition nor creating a new partition. I used G-Parted from hiren boot cd but it says there is no partition table, you need to create a partition table. But actually I have 5 partitions already. And I thought of restarting might fix it. But after showing post screen my laptop show grub error. I don't know what to do, and I tried to install back-track again to fix the problem but it also says that i do not have any partitions. I can only boot windows by passing through hiren boot cd. But most of the time My computer is not recognizing the external dvd drive, nor the internal so i have to restart again and again, hoping to catch the time computer recognize the dvd drive. Can I change the boot loader to correct the grub error? SOLVED : I have solved the grub error by writing MBR again by using EasyBCD But I still have the format error.

• "sr0" I/O read boot error in Xubuntu 12.10

  - by Entropicurity

  Just recently upgraded Xubuntu 12.10 after having installed 12.04 originally. Ever since that happened, any time I inserted a disk into my DVD/CD reader/writer I would end up getting a number of error messages from my DVD player/Audio player softer, typically with any of them either crashing or returning a GStreamer backend error. So doing some research I tried to mount it manually, and it typically returned the error messages you'll see below: (using the dmesg | grep "sr0" command) [17545.435584] end_request: I/O error, dev sr0, sector 0 [17545.492968] sr 3:0:0:0: >[sr0] [17545.492981] sr 3:0:0:0: >[sr0] [17545.492992] sr 3:0:0:0: >[sr0] [17545.493003] sr 3:0:0:0: >[sr0] CDB: [17545.493020] end_request: I/O error, dev sr0, sector 0 [17545.493058] EXT3-fs (sr0): error: unable to read superblock [17545.553224] sr 3:0:0:0: >[sr0] [17545.553237] sr 3:0:0:0: >[sr0] [17545.553247] sr 3:0:0:0: >[sr0] [17545.553258] sr 3:0:0:0: >[sr0] CDB: [17545.553275] end_request: I/O error, dev sr0, sector 0 [17545.553312] EXT4-fs (sr0): unable to read superblock [17545.611482] sr 3:0:0:0: >[sr0] [17545.611494] sr 3:0:0:0: >[sr0] [17545.611504] sr 3:0:0:0: >[sr0] [17545.611514] sr 3:0:0:0: >[sr0] CDB: [17545.611531] end_request: I/O error, dev sr0, sector 0 [17545.611568] FAT-fs (sr0): unable to read boot sector When I grepped this, the number of error messages just seemed to spill all over the screen, and typically all revolve around the I/O error. I then went into VLC and tried to run the stuff through there, but for some reason it won't read with the default devices. Instead I have to manually input sr0 into each of the /dev/ references and it will play just fine, until I exit out of the program, at which point I have to re-input everything. I have already installed all the media dependencies, both open source and restricted, through the software center. I just found this strange, as out of the box 12.04 there wasn't any problem what so ever. At this point, it could be that all my audio CD's are not in a format that is familiar with the OS (I've read in some places that EXTF4 has issues with this) but I don't see how that could be a problem when the above error messages even tested to see if it is EXT3 as well? I've tried my best to troubleshoot this up till now using existing topics, but it seems that this is a regular problem with a multitude of varying factors that incorporate into it, including but not limited to read/write problems with the format of the CD and right protection. Is there something integral that I am missing?

• Windows 7 boots to black screen with blinking cursor

  - by murgatroid99

  I have an Alienware M17x that dual boots into Ubuntu 11.04 and Windows 7 Home Premium. Currently, the computer starts at the GRUB loader and will boot into Ubuntu, but if I try to boot into Windows, I immediately get a black screen with a blinking cursor in the upper left corner. The output of fdisk -l is Device Boot Start End Blocks Id System /dev/dm-0p1 1 5 40131 de Dell Utility Partition 1 does not start on physical sector boundary. /dev/dm-0p2 6 1918 15360000 7 HPFS/NTFS Partition 2 does not start on physical sector boundary. /dev/dm-0p3 * 1918 64772 504878877+ 7 HPFS/NTFS Partition 3 does not start on physical sector boundary. /dev/dm-0p4 64772 77827 104858625 5 Extended Partition 4 does not start on physical sector boundary. /dev/dm-0p5 64772 67204 19531008 83 Linux /dev/dm-0p6 67204 74498 58593536 83 Linux /dev/dm-0p7 74498 77577 24731648 83 Linux /dev/dm-0p8 77578 77827 2000128 82 Linux swap / Solaris I have used the Windows rescue CD, and run the automatic error fixer until it finds no errors. I have run chkdsk /R on both the main Windows 7 (/dev/dm-0p3) partition and the recovery partition (/dev/dm-0p2). I set the main Windows 7 partition to be active. I also tried running in the recovery console the commands bootrec /fixmbr bootrec /fixboot bootrec /rebuildbcd None of these helped and the last set of commands deletes grub, which I then have to reinstall from Ubuntu. I think the last thing I did in windows before this started was install the newest ATI driver for my video card. This would suggest using system restore, and I actually had a restore point earlier (after the problem started), but after whatever I did that restore point does not appear in the list on the recovery disk any more, so I cannot do a system restore. Is there anything else I can try to make Windows boot properly again? Edit: Running the suggested commands bootsect /nt60 c: bcdboot c:\windows /s c: was also ineffective.

• Why is my new PC so slow at startup?

  - by rumtscho

  Bought a new PC this weekend, and it works really good. Only I have one big problem: startup time. Its BIOS needs 62 sec to load, then from Grub start to pw entering screen it's another 26 sec. I think this is a lot, because my old PC needs 34 sec for BIOS and another 8 sec to pw screen. After I enter the pw, the desktop is usable with practically no delay on both. The new PC is a core i7-930, running a Lucid Lynx 64 bit from a Intel Postville SSD (no internal HDs). The old PC is a Pentium 4 celeron (forgot the clock speed) running a Lucid Lynx 32 bit from an ATA 100 hard drive. Neither PC is overclocked. The new one has boot sequence 1.DVD ROM, 2.SSD (connected over SATA in AHCI mode), 3. removable drive. The old one boots from 1. DVD ROM, 2. HDD, 3. Floppy. Neither has a second OS installed. The new one has less software installed than the old one (I think), but the boot time difference was noticeable even before I made any installs. As far as I know, just the SSD should be enough to make a noticeable difference in boot time. I thought that having a good mainboard on the new PC as opposed to the basic office model on the old one would also mean a faster loading BIOS. If these assumptions are right, I guess I must have misconfigured something in the BIOS of the new PC. How should I configure it for a fast boot? It has an ASUS P6X58D board with an AMI BIOS, if you need the BIOS revision number I could post that too.

• How to fix UNMOUNTABLE_BOOT_VOLUME (0x000000ED) on my Windows XP DELL laptop?

  - by Neil

  I have a Dell Latitude D410. Running Windows XP. I am receiving the STOP: 0x000000ED (0X899CF030,0XC0000185,0X00000000,0X00000000) Blue screen. Initially, I tried everything specified with the Microsoft KB articles. At this time, I was able to boot into the general safemode. I pulled the hard drive and was able to run chkdsk on it- it noted that it had fixed some errors, but I was still unable to boot. I put a brand new hard drive in the laptop. Windows XP installation worked up until the reboot, at which time the exact same error message came back up. What I have tried (all since the new hard drive was installed): chkdsk /R All suggested solutions in Microsoft KB articles Reseating RAM Opened laptop, reseated all connectors, looked for signs of damage (saw none) Reset BIOS options to default Ran the basic Dell diagnostics I have looked at the current entry:How can I boot XP after receiving stop error 0x000000ED - I am currently in the process of downloading the Ultimate Boot CD to use as a test, but I am not holding out a lot of hope as I really doubt this brand new Hard Drive is bad. Can anyone think of other areas I am missing? Ran MEMTEST86+ V4.10 for 15 passes (overnight). 0 Errors EDIT: FORMATTING

• Windows 7, Black screen with cursor, impossible to logon

  - by PJC

  First - I have gone through as many possible solutions I've found here and elsewhere. [Edit - to describe the issue in more detail, the PC appears to boot correctly, but instead of the logon screen, I have been getting a black screen WITH the pointer cursor, and it responds correctly to the mouse. Pressing CTL-ALT-DEL brings up the logon screen's background, but with no logon area nor any other content. This screen was at the full resolution before I uninstalled the graphics driver in safe-mode.] I also just ran a full up-to-date AVG scan from boot media. [Edit - the AVG scan, which was updated to today's virus signatures, found no issues at all.] So - steps I've tried: Safe Boot, Restore from before the issue - done, no help. Uninstall the graphics driver - done, now i have a 1024x768 fallback screen, still no way in. sfc /scannow - only doable from Safe boot obviously, but no change. [Edit - booting from restore media, performing a startup repair and...]Restore further back - restored to 2 days ago, and I'd had many reboots since then with no problem. Enable autologin to try to get beyond the login screen - done, doesn't work. It seems the best advice is complete reinstall, but I really don't want to do that because it'll take 3-4 days to add all the apps I use. Some key points to note - in both states - before and after removing the video driver, I always had a mouse cursor on the screen. CTL-ALT-DEL flashes up the login background, but no login info. I can (and often do) reinstall from scratch, but was at a fairly stable state before this, and would prefer not to. -Paul

• Windows 7 clean install becomes corrupt after reboot (repeated many fresh installs)

  - by pjotr_dolphin

  My laptop keeps crashing on boot after clean Windows 7 install. Ok, here is the story, and some fact. Computer: Samsung NP900X3C-A04HK (256GB SSD, 8GB RAM) OS to install: Windows 7 Ultimate SP1 (not from Samsung, own fresh Win) I purchased this laptop about a year ago, never booted it into the Windows Home that was installed on it, installed directly Ubuntu on the machine. Full disc encryption was the selected install, so of course it wiped the complete disc (including Samsung Recovery Partition). After some time, I felt like going back to Windows, as Windows 7 is actually quite nice. So I went to buy a fresh Windows 7Ultimate with SP1. Now to the tricky part. Windows installs perfectly, and after installing all Windows updates, drivers from Samsung, software I need, it is time for shutting it down and go to bed. Starting it up again, and it is not booting, these are the type of errors I have gotten so far (fresh installed it more then a dozen times now, and tried different suggestions from threads on the net). Windows failed to start... Status: 0xc000000f Info: The boot selection failed because a required device is inaccessible. File: /boot/bcd Status: 0xc000000f Info: an error occurred while attempting to read the boot configuration data. And some other errors, not all the same. Not memory of this. I have run different disc checks, and all says my SSD is in perfect shape. Note: Soft reboots from Windows menu works, never gets corrupted. But if I Shutdown and then start it up again, this is when it happens. Can someone help me not get back to Ubunut? What can be the cause, and how can it be fixed so I do not get there problems again?

• How can I restore the registry keys from another C drive? (Windows 7 64bit)

  - by graham3d

  I ran Uniblue registry booster on my system which was working fine. It did a full back up of the registry keys. Now I cannot boot from that disk. I also cannot get into the BIOS! To restore the registry I have to run Uniblue registry booster from within windows. I cannot get there. I can boot up on another C drive, and can see the files on the drive with the problem. Is there any way I can find the Registry Booster backup files and restore it from the other disk? Or find the registry backup and upload it into the registry so I can boot off the other disk again? Or, Can I do a windows repair from the other disk? NB: not getting in to the bios means I cannot boot off the CD/DVD! (I can use the DVD drive from within windows) Any ideas? I do not want to reinstall everything yet again, it takes about 6 hours.

• VNC failure on Xen

  - by BCable

  The following config works and creates a good VM in Xen: # Kernel Setup kernel = "/boot/vmlinuz-2.6.18.8-xenU" # Memory memory = "256" # Disk disk = [ "file:/opt/xen/domains/110/sda1.img,sda1,w", "file:/opt/xen/domains/110/swap.img,sda2,w" ] # container name name = "110" hostname = "boo" # Networking vif = ["type=ieomu, bridge=xenbr0"] # VNC vnc = 1 #vfb = [ 'type=vnc,vncdisplay=2,vnclisten=0.0.0.0,vncpasswd=110' ] # Behavior Settings root = "/dev/sda1" extra = "fastboot" But when I uncomment the VFB line, I get the following error after it hangs for at least 30 seconds: [root@customer 110]# xm create boo.cfg Using config file "./boo.cfg". Error: Device 0 (vkbd) could not be connected. Hotplug scripts not working. Any ideas? Part two of this question: Sometimes it actually works, and a port is opened. When this happens, nmap shows the VNC ports open and I can connect via the VNC client, but it just hangs at "Connection established." and no VNC display shows up. I've tried multiple VNC clients (TightVNC, TightVNC Java Console, RealVNC), but they all fail to connect. Does VNC through Xen require X to be started in order to function? I was under the impression that it would show the console screen, so I'm confused as to why all these issues are occurring. Thanks!

• Resize Win2003 system+boot partitions to bigger disks & different controller?

  - by ane

  Have an old Win2003 server with 1 SCSI hard drive partitioned as follows: D: boot (includes D:\ntldr, boot.ini, etc.) C: system (includes C:\WINDOWS) Want to move the whole system to new hardware with bigger drives and different controllers. Specifically, C: to a 300GB SAS drive, and D: to a 2TB SATA drive. Tried: VMWare Converter - VMWare Server - Diskpart Result: Diskpart refuses to resize system or boot disks VMWare Converter - VMWare Server - GParted Result: Will not boot (see http://serverfault.com/questions/219868/resize-ntfs-system-partitions-with-gparted ) Attach original VMWare disk to a duplicate VMWare install - Diskpart Result: Will not boot (goes to Directory Services Restore mode) Backup Exec System Recovery Server Edition 2010 with Restore Anywhere (tried restoring both to VMWare and to the bare system, without VMWare) Result: Windows Boot error: Could not read from the selected boot disk. Check boot path. Supposedly this is a boot.ini problem, so I try bootcfg /rebuild from the recovery console. Says it can't find windows partition so it can't rebuild. Thought about Ghost but it's completely different hardware/controllers that we're restoring to, so I doubt it would boot. Reinstalling Windows from scratch is not an option due to critical custom software heavily embedded on the original machine. Has anyone been in a similar situation (with unusual boot/system partitions) before and figured out how to resize onto different disks?

• After RAID failure SBS 2008 issues logging in and Exchange store does not mount

  - by Josh R

  today has been one of those days. Yesterday a hard drive in our Dell Poweredge 2900 server failed and the RAID array didn't degrade gracefully, so I called Dell (Server still under warranty) and got an engineer to work though the RAID issues with me. He was a nice guy but didn't do too much. We tried to put the RAID in a state where it was bootable and even though we only lost one disk there are still issues with the server. Once we got the server to boot there was an error message saying that the logonui.exe was corrupted and we needed to run chkdsk. I clicked through the error messages and the login screen never came up. So I power cycled the server and it chkdsk automatically but the login screen didn't appear. I tried safe mode, no difference there either. So the issues I am currently having are: 1) The server boots up, the loading windows screen comes up then it dumps me into a black screen where I can only see my mouse cursor. Ctrl+Esc doesn't work Ctrl+Alt+Del doesn't work 2) Some of the services come up: DHCP, DNS, DFS, and Print come up 3) The exchange information store and transport service don't start - I tried using mmc to connect to services.msc on the computer and start them but they throw an error message of "Can't start because group or dependency failed" Has anyone had a problem like this? Can anyone offer some guidance? Thanks a bunch!

• "TMGR is Missing" after repair-installing Windows XP

  - by djzmo

  Hello there, I have two OSes installed in my computer. - Windows XP Professional - Windows 7 Ultimate (Release Candidate 1/Build 7100) I used the Windows 7 boot loader by default to choose between OSes. When I was using my WinXP, my computer gets lagged suddenly and continuously, and the only way to fix it is by repair-installing it (because I've experienced this many times before, but without W7 installed). Everything goes OK. But when my XP was successfully reinstalled, I cannot boot my Windows 7 anymore. Every time I tried to boot the harddisk that contains W7, an error appeared. "TMGR is Missing". Now I have no idea how can I get back to my Windows 7. Any kind of help would be appreciated! :)

• What happens when the USB key or SD card I've installed VMware ESXi on fails?

  - by ewwhite

  An SD (SDHC) card installed in an HP ProLiant DL380p Gen8 server running VMware ESXi just failed. I encountered some rather ominous looking messages on the vCenter console and in the HP ProLiant ILO event log... Lost connectivity to the device ... backing the boot filesystem. As a result, host configuration changes will not be saved to persistent storage. Embedded Flash/SD-CARD: Error writing media 0, physical block 848880: Stack Exception. VMware advocates the use of USB and SD (SDHC) boot devices for ESXi. It was one of the main reasons the smaller footprint ESXi was developed (versus the older ESX). I've spent much time highlighting the differences between ESXi's installable and embedded modes to coworkers and clients. However, these failures do seem to happen. In this case, this is my third instance. Luckily, this is a vSphere cluster with SAN storage. What steps should be taken to remediate this failure?
