• how to skip grub dual boot option menu entirely (without picking an OS to boot)

  - by bevcan izBevk

  I'd like to skip the entire Grub 2 interface, where I have to decide booting Linux or Windows im running linux ubuntu lastest version (14.04.1 LTS) and windows 8.1 both 64 bit versions. I've installed easyBCD software, which I want to use as (my only) boot manager. Issue: whenever I run my computer, I get grub interface to pick Linux or Windows, after that I get easyBCD interface where I have to pick linux or windows again. If both choices are the same, proper system boots, else I get thrown back to beggining (grub UI). I'd like to somehow delete / skip grub from appearing. TLDR title :) thank you for helping!

• Ubuntu not showing hard drive

  - by ojek

  I have a laptop which had a broken installation of Windows 7 installed on it. I created a Ubuntu live USB and tried installing Ubuntu over that Windows 7. After a few minutes, I got an error message, so I needed to restart the computer. Now the laptop says that there is no bootable device - reasonable message given that there was an error during Linux installation. However: BIOS can see my hard drive, When I start Ubuntu in live mode, and try either sudo fdisk -l or gparted, it doesn't show any hard disk drives. I am 90% sure that the hard drive is broken, but it is weird that BIOS can see it, and Ubuntu doesn't. How can I be 100% sure about that hard drive? Is there any additional way of detecting my hard drive from Ubuntu?

• Configuring MPI on 2 nodes

  - by Wysek

  I'm trying to create really simple "cluster" from 2 multicore computers using openmpi. My problem is that I can't find any tutorials on that matter. I don't want to use torque because it's not necessary in my case nevertheless all tutorials give configuration details either about torque or mpd (which doesn't exist in openmpi implementation). Could you give me some tips or links to appropriate manuals? Steps I've already completed: - openmpi installation - network configuration (computers see each other) - ssh password-less login to second computer I tried using machinefiles without further configuration and with just 2 IPs in it. But jobs don't seem to start at all after initialization part. (MPI seems to work because I'm able to scatter jobs on multiple cores of both computers without communication between them).

• Is WinRT really as secure as it's made out to be?

  - by IDWMaster

  Prior to releasing Windows 8, Microsoft claimed that all WinRT apps are cleanly removed from your computer after uninstalling them, and that WinRT apps should not interfere with other running applications, because they are ran in a "sandboxed" environment. Microsoft has also claimed numerous times on Channel9 that Windows 8 apps are not ran in a VM. So my question is; are these claims accurate? If the application is not running inside of a VM, how is it possible to protect the system against malicious code at runtime, assuming the attacker was able to bypass the screening process of the Windows Store system? Microsoft allows "native code" in WinRT apps, so wouldn't it be possible (using hand-coded assembly or some odd pointer manipulation trick to call functions outside of the sandboxed environment and interfere with the rest of the system, if it's really "native code" and not some VM?

• Ubuntu 12.04 takes too long to boot

  - by msPeachy

  I've recently encountered the following error message: mount: mounting /dev/disk/by-uuid/3f7f5cd9d-6ea3-4da7-b5ec-**** on /root failed: Invalid argument mount: mounting /sys on /root/sys failed: No such file or directory mount: mounting /dev on /root/dev failed: No such file or directory mount: mounting /sys on /root/sys failed: No such file or directory mount: mounting /proc on /root/proc failed: No such file or directory Target file system doesn't have /sbin/init. No init found. Try passing init= bootarg. Busybox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4) built-in shell (ash) Enter 'help' for a list of built-in commands. (initramfs) _ I run sudo fsck /dev/sda2 which is the Ubuntu ext4 root partition via LiveCD. It checked and fixed the file system. The next time I boot, Ubuntu started to load with the Ubuntu logo and the dots underneath for several hours (with the mouse pointer active on the screen), I even let the computer on overnight but still it did not successfully boot or got to the login screen in the morning. I booted again with the LiveCD and checked the NTFS partitions with ntfsfix and again the NTFS partitions was checked and fixed successfully. I also edited my fstab and commented out the lines that auto-mounts the NTFS partitions. The next time I boot, it took almost 20 minutes for Ubuntu to get to the login screen, after typing the password it took an additional 10 minutes for Ubuntu to get to the desktop. On the desktop, it take several minutes to open any program, displaying the Dash alone takes 5 minutes! Is there a fix for this without having to reinstall Ubuntu? I don't see or get any errors, Ubuntu is just taking too long to boot and to run programs. Please help!

• Mysterious "media" volume mounted on desktop Mac OS X

  - by Allen

  I have a mysterious volume mounted on my desktop that I can't seem to forcibly unmount. I've tried using umount and also diskutil, but it seems to automatically remount itself. I've copied my hdd with Time Machine, and copied it onto a new computer, and it also has the drive mounted on it. It's not pointing to anything and I can't open it, nor can I forcibily remove it by hand with rm -Rf. Any ideas? I noticed this problem after I upgraded to Mountain Lion from Lion. It causes problems because when I try to select a file using the built in Finder dialog box, it freezes for a few minutes because it tries to cache or read into the "media" mounted volume.

• Bluetooth headset turns off when Skype call ends

  - by Claude

  For about 6 months, I haven't been able to use Skype because when I end a Skype call, my Plantronics Callisto headset gets turned off. I'm paralyzed so I can't turn it on manually. I have a Sony VAIO computer running Windows 7. I have updated my Bluetooth dongle software, uninstalled and reinstalled Skype and uninstalled Skype and gone back to an earlier version; all to no avail. Neither Plantronics nor Skype technical support are interested in looking into this problem for me.

• Building an intranet

  - by WernerCD

  I'm researching for a project I'm going to be doing at work on the side... I work for a small hospital and we recently upgraded all the browsers inside our intranet to IE8 (Goodbye 6 :). We have a small, obsolete intranet built by someone who isn't a web designer... functional enough, but annoying to maintain and really sparse. What I'm wanting to do... is use a good framework. I'm looking for suggestions... I'm looking for something Windows IIS based. I'd love windows authentication - with the ability to delegate sub-sections of the website to managers. Right now it's my job to add/update/delete anything from the site... I'd like something not complicated that can be delegated to non-technical people. Like... the Cafeteria Manager should be able to update the menu without putting a ticket into me. She'd log into her computer, open the intranet (which would use her windows log-on to identify her) and have elevated privileges to edit her section of the intranet. If I have to "extend" a good framework to get Windows Authentication, I'll do it... but I'd prefer it to be baked in. What are some good frameworks, tools and places to start? While this isn't a "Huge" project... it's going to be bigger than the basic stuff I've done before and I'd like a good place to start.

• Web Site Monitoring/Tracking Freeware

  - by jsmith

  I need to be able to track Web Sites visited on a computer and send them to an email address on a daily basis. Keylogger software seems like too much, I want something lightweight that simply monitors websites visited and forwards them on. I was hoping for freeware, but if it's cheap/simple and easy to use I'm willing to pay. I know similar questions have been asked about website traffic monitoring, but it's not quite the same thing, and I can't seem to find an answer to this question anywhere. Thank you ahead of time.

• How to force Windows to call the partition it installs on C:?

  - by maaartinus

  I'm going to install Windows XP from a CD and want to make sure it calls the partition it lands on C:. The target partition is the first one on a SATA disk, which is not the first one in my computer. There's no IDE disk there. I don't think I can swap the disks, as I'm using a fake RAID and really don't want to get problems with it. The target partition is on a normal disk. I know it may be unimportant, but I don't want to run in any problems I can avoid. I've seen a question slightly related to it, but I'm not going to install from a USB.

• Audible Books does not install my books into my iTunes and wants me to do it manually, I can't figure out how

  - by Alice

  Audible Books fails to install into iTunes I am using a desktop with Windows 7 64 bit. I have been downloading Audible Books for 3 years and have 85 installed. Several months ago downloading them did not put them in iTunes and the system wants me to import them manually. You start with "C\Program Files\iTunes\ and add two lines..... I know I need to choose the destination for 64 bit, but I do not see iTunes and I do not know how to put this title into iTunes if I can locate it? The folks at Audible wasted a lot of my time but were zero help! How can I get these books into my computer?

• Help me convert my gaming headset plugs (mic & stereo sound) to a single 2.5mm monaural plug

  - by Flotsam N. Jetsam

  I have a seldom used piece of computer hardware I'd like to connect a gaming headset to. The headset has two 3.5mm plugs (mic and sound) like this: The jack I need to plug into is a 2.5mm monaural (don't ask me why--I know it sounds goofy but it's for someone else who's very picky). I googled a few different ways but I could only find splitters such as this for going from 2 x 3.5mm to 1 3.5mm. If I could find one that could combine it properly to 1 3.5mm, I could then find a 3.5mm to 2.5mm adapter. I know I could probably vivisect and work something out, but I need it to be very clean. Any ideas?

• Name of my sql server instance from outside the network

  - by Michel

  Hi, normally i connect to my sql server instance from my local computer, and then the server name to connect to is the name of my laptop. So i can connect to server instance 'MichelLaptop' But now i'm trying to connect to my server from outside my network, and the first thing i wonder is: what is the name of the instance? i've made a redirect to my local machine in the DNS of my domain, so i said (this is not the real data) testsql.mydomain.com goes to 190.191.192.193 and when i ping testsql.mydomain.com, i get a response from 190.191.192.193 But what then is the server name?

• Find out what resource is triggering bad password attempt?

  - by Craig Tataryn

  Background: Have a problem at work where I am constantly being locked out of my computer. We are in an environment that has a Domain Controller and we use Active Directory for authentication. By going through my normal workflow while on the phone with Desktop Support we were able to track the bad password attempts that were causing the lockouts to an application: "Eclipse". This is the application I use to do software development. I immediately thought it was a cached password for our SVN server that's the culprit, however the desktop support person couldn't tell me which resource the password attempt was being made against (i.e. which URL for instance). Question: Is there a way that I can monitor bad authentication requests made by an application on my desktop and find out what resource they are attempting it against?

• When I plug an HDMI cable into my MacBook Pro with Retina Display, the resolution of the retina display changes

  - by Tyler Crompton

  I had an HDMI cable plugged in for a while that connected to a TV with no power. The retina display randomly flashed blue after a while and then changed to a different resolution (possibly 1080p). I unplugged the HDMI cable and nothing happened. So I restarted the computer to no avail. I was still having issues. So I fiddle with some settings after plugging in the HDMI cable again. Now, the retina display appears fine when no HDMI cable is plugged in, but when there is one plugged in, the resolution changes. I have mirroring turned off (which is what I want). The resolution of the retina display when an HDMI cable is plugged in is 3,360px x 2,100px (according to the size of a screenshot) and the external display is 1,600px is 900px. How can I fix the retina display to show with the correct resolution.

• Linux cannot alter partition table of main hard disk of my laptop

  - by djechelon

  I run openSUSE 12.2 on my ASUS N76VZ laptop. My problem is that I cannot alter the partition table of first hard disk /dev/sda1. YaST partitioner says it's unreadable, but actually it can read it but not alter it. It doesn't tell me anything else, except that I can wipe the partition table (having to reinstall Windows for the third time). Since I want to create new partitions on that disk, how do I fix the partition table layout? I could create new partition from Windows Computer Management and format them in Linux. I could do this, but it doesn't explain the problem

• Can't boot after compiling 3.1 kernel, can only get to terminal

  - by olssy

  Long story short: I tried compiling kernel 3.1 on Ubuntu 11.10 at the same time I had an update waiting for a reboot. Computer would boot to a black screen and would hang there. Ended up installing 11.10 on top of old install with a Live CD. Now I had a purple screen on bootup but it would end up booting. Realized Grub was the problem and tried some stuff but nothing worked. I ended up trying to install propriety ATI video drivers and since that nothing has worked, no grub menu(purple screen) and when it boots into the kernel it ends up hanging, I can sometimes get a terminal up with alt-fx. I have tried removing the ati drivers with the ati script, purging my fglrx driver, reconfiguring my xconf.org and following any tutorial I can find about fixing a broken graphics driver, but to no avail. I've gotten to a point were it seems that the ati propriety drivers are correctly loaded but it still has no grub boot menu and won't boot into Ubuntu. I've chased down my logs and this line is from kern.log: unity-greeter[3269]: segfault at 0 ip b7245cbbsp bf9d3900 error 4 in libgio-2.0.so.0.3000.0[b71ad000+142000] That line leads me to believe I don'T have the correct libgio-2 librairy on my system but have no idea how to find out what package has the correct version... My xorg.conf has no errors and seems to imply the fglrxdrm module got loaded correctly. Would be a bit complicated pasting the whole file here but if it would help I'll post it. LAstly, running fglrxinfo give me: Error: Unable yo open display (null) Any help or link to another tutorial would be appreciated. Thanks.

• I believe I need a wireless access point, but can I do it with a wifi router?

  - by Flotsam N. Jetsam

  My needs are simple, I think: I have a laptop upstairs with a usb wifi that I use to connect to my neighbor's wifi which I share (with their knowledge). I have a laser printer downstairs that my wife doesn't wants to stay down there (big, bulky and ugly), but that we both need to print stuff off. It has wired networking and I have wired hub and router down there. The usb wifi on the laptop has absolutley the best reception I've ever seen or heard of. I cannot get onto the neighbor's net with the thing downstairs though--sortof in the ground. What do I need downstairs to give printer access to my laptop wirelessly? One thing I can't do in this solution is have a computer on downstairs, so I would think that would eliminate a usb solution.

• Bluetooth connectivity

  - by Viniketa

  computer: Samsung All in One PC OS: Windows 7 (up-to-date) BT Radio: Broadcom I have Bluetooth speakers I have successfully used with the system in the past. In fact, I had them set as default speakers so audio would transfer when I turned them on. No longer. Now, they show as 'disconnected'. Asking for connection gives no response. Option to set as default is greyed out. Bluetooth view utility gives an error of 10049 when I try to connect (supposedly, the means an invalid device address). I uninstalled the device and re-installed. No help. Any advice? Thanks in advance.

• Random timeout now and then

  - by KenavR

  Maybe this is a to generic question, but since we have this issue for quite a while now, I give it a shot. We have some applications which use HTTP for the connection between the client (website or fat-client) and the server. The Computer who runs this applications is in a Network behind a firewall and a proxy, the server isn't inside the same network. The problem is that every now and then the https Request times out and depending on the Client the Application "hangs" or does some other funky stuff. The problem is definitely inside our network, because if i try the applications outside our network it works fine. Can you give me a hint where i can most likely find the problem?

• Why is my USB data transfer so slow?

  - by Dave M G

  Whenever I do any kind of file transfer using USB, whether to a USB stick, or with my Android phone, or anything else, it is ridiculously slow. It says 59.8 KB/sec, which would be an awesome speed if this were 1991 and I was using a modem to dial up to my local BBS. Surely USB technology is better than that...? 37 seconds to move less data than the equivelent of 1 MP3 file? Also, regardless of what it says about speed and time, the reality is much, much slower. I routinely see it say something like "37 seconds left" and have to wait for minutes. Sometimes, if I want to move large amounts of files, it can say it will take 8 hours or more. Is this normal? My computer may not be the most awesome on the market, and about a year old, but it's an i5 with 4GB RAM and modern components, so surely this isn't the hardware's fault. What can I do to get better USB data transfer performance? Also, I did look at this question, but my newbie eyes don't see anything that look like an actual solution, just a lot of discussion about what transfer rates could or should be. Update: As requested in the comments, I've generated a whole bunch of output from the command line, and put it on Ubuntu Pastebin. Please see it here.

• Window will read this particular DVD which it usually doesn't, if it spins for a longer time

  - by curious_kid

  I'm unable to figure out what's wrong with my system. My computer will read this particular DVD sometimes and mostly it won't. When trying to explore the DVD, I get error "Windows can't access this disc" ( note : It doesn't says that the "disc is empty", the normal error which I generally get when I try to read a scratched DVD ). Ok now the mysterious part, I have noticed that everytime DVD spins for a longer time ( like for 1 -2 minutes), window will read it without any problem. Extra information : The DVD I'm talking about doesn't have any scratches. I tried cleaning the DVD Drive with a lens cleaning CD. DVD was burned in multisessions. My system have window 8 installed. Question I wanted to ask : What makes DVD spins for a longer period of time sometimes ? If possible how can I make window spin the DVD for longer time ? Any solution to my problem ?

• Converting an external hard drive to internal

  - by Nathan DeWitt

  I have a WD Elements 1 TB external drive. I'm in a pinch and I need an internal SATA drive. How do I find out if the drive in here is actually a SATA drive? Edit: The WD Elements is a really nice external drive. I gently pried open the top and slid out a 1 TB Caviar Green hard drive. There were four black rubber brackets that slid off easily. One screw removed the SATA -- USB, and then I slid it into my computer.
