[SOLVED] Bricked computer - GRUB won't show

I'm not sure what happened, but I rebooted my computer, and now it won't show the boot loader page.
I had updated some packages, but I don't think grub was among them.
My boot setup is grub and EFI.
I booted using a recovery disk (systemrescuecd), but I don't even know where to start looking.
My initial try was to choose "boot existing installation" on the recovery disk. Unfortunately systemd reported several "failed to mount" and then hung.
parted /dev/sda print
Shows my EFI partition with the boot and esp flag.
I'm able to mount all the partitions and browse the files.
Any idea where I should start looking for the problem?
And is there a "better" rescue disk with more up-to-date software? I see grub-install on the rescue disk shows version 0.97.

Thanks. This is mighty strange though.. I couldn't find any package upgrades that should have modified my boot.
Reinstalling grub fixed the problem, but I don't like that I have no idea what caused the problem in the first place.

  • I have a gen3 iPod touch.  It shows the battery charging when I plug into my PC, but will not show as an extra drive in "my computer" and won't show up in iTunes either.  Can anyone help please?  I have exhausted all "help" options.

    I am trying to get my iPod touch (3rd gen), to show up in "My Computer" and in iTunes.  I am using a usb cable and it is connecting okay, because the battery is charging.  It won't show up as an external drive on my computer, and nothing in iTunes either.  I have used the exact same usb cable and plugged into the exact same usb port with a different iPod touch without having this problem.  I have swapped them back and forth and it seems to be a problem with this particular iPod, because the other shows up just fine.  I have already downloaded and installed the latest iTunes update, and I already restarted the computer afterwards.  The other iPod is a 4th gen touch, but that really shouldn't matter.  I would greatly appreciate anyone's help on this matter.  I know that I can't be the first person that this has happened to.  Thanks.

    Dude you have a jailbroken phone as stated in your first post, no need to do a second post.
    As per the forum term of service you can't get help here.  Use google.
    that's the downfall of jailbreaking your phone.

  • Just updated my iphone to ios6 and when i plug it into my computer it won't show up in itunes???

    I have just updated my itunes as well

    Have you got the latest version of itunes?  I assume you have because you say you have iOS 6.  Try a different cable or a different USB port so if that helps

  • 20g ipod won't show on computer

    my ipod won't show up on my computer anywhere, it is making wierd hard drive noise, can someone please help me.

    Hello,
    If a sad iPod icon or an exclamation point and folder icon appears on your iPod’s screen, or with sounds of clicking or HD whirring, it is usually the sign of a hard drive problem and you have the power to do something about it now. Your silver bullet of resolving your iPod issue – is to restore your iPod to factory settings.
    http://docs.info.apple.com/article.html?artnum=60983
    If you're having trouble, try these steps at different levels one at a time until the issue is resolved. These steps will often whip your iPod back into shape.
    Make sure you do all the following “TRYs”
    A. Try to wait 30 minutes while iPod is charging.
    B. Try another FireWire or USB through Dock Connector cable.
    C. Try another FireWire or USB port on your computer .
    D. Try to disconnect all devices from your computer's FireWire and USB ports.
    E. Try to download and install the latest version of iPod software and iTunes
    http://www.apple.com/ipod/download/
    http://www.apple.com/itunes/download/
    F. Try these five steps (known as the five Rs) and it would conquer most iPod issues.
    http://www.apple.com/support/ipod/five_rs/
    G. Try to put the iPod into Disk Mode if it fails to appear on the desktop
    http://docs.info.apple.com/article.html?artnum=93651
    If none of these steps address the issue, you may need to go to Intermediate level listed below in logical order. Check from the top of the lists to see if that is what keeping iPod from appearing on your computer in order for doing the Restore.
    Intermediate Level
    A. Try to connect your iPod with another computer with the iPod updater pre-installed.
    B. Still can’t see your iPod, put it in Disk Mode and connect with a computer, instead of doing a Restore on iPod Updater. Go and format the iPod instead.
    For Mac computer
    1. Open the disk utility, hope your iPod appears there (left hand side), highlight it
    2. Go to Tab “Partition”, click either “Delete” or “Partition”, if fails, skip this step and go to 3
    3. Go to Tab “Erase” , choose Volume Format as “MAC OS Extended (Journaled), and click Erase, again if fails, skip it and go to 4
    4. Same as step 3, but open the “Security Options....” and choose “Zero Out Data” before click Erase. It will take 1 to 2 hours to complete.
    5. Eject your iPod and do a Reset
    6. Open the iPod Updater and click “Restore”
    For Window computer
    Go to folder “My Computer”
    Hope you can see your iPod there and right click on the iPod
    Choose “Format”. Ensure the settings are at “Default” and that “Quick Format” is not checked
    Now select “Format”
    Eject your iPod and do a Reset
    Open the iPod Updater and click “Restore”
    In case you do not manage to do a “Format” on a window computer, try to use some 3rd party disk utility software, e.g.“Partition Magic”.
    C. Windows users having trouble with their iPods should locate a Mac user. In many cases when an iPod won't show up on a PC that it will show up on the Mac. Then it can be restored. When the PC user returns to his computer the iPod will be recognized by the PC, reformatted for the PC, and usable again. By the way, it works in reverse too. A Mac user often can get his iPod back by connecting it to a PC and restoring it.
    Tips
    a. It does not matter whether the format is completed or not, the key is to erase (or partly) the corrupted firmware files on the Hard Drive of the iPod. After that, when the iPod re-connected with a computer, it will be recognized as an fresh external hard drive, it will show up on the iPod updater.
    b. It is not a difficult issue for a Mac user to find a window base computer, for a PC user, if they can’t find any Mac user, they can go to a nearest Apple Shop for a favor.
    c. You may need to switch around the PC and Mac, try to do several attempts between “Format” and “Restore”
    Advance Level
    A. Diagnostic mode solution
    If you have tried trouble shooting your iPod to no avail after all the steps above, chances are your iPod has a hardware problem. The iPod's built-in Diagnostic Mode is a quick and easy way to determine if you have a "bad" iPod.
    You need to restart your iPod before putting it into Diagnostic Mode. Check that your hold switch is off by sliding the switch away from the headphone jack. Toggle it on and off to be safe.
    Press and hold the following combination of buttons simultaneously for approximately 10 seconds to reset the iPod.
    iPod 1G to 3G: "Menu" and "Play/Pause"
    iPod 4G+ (includes Photo, Nano, Video, and Mini): "Menu" and "Select"
    The Apple logo will appear and you should feel the hard drive spinning up. Press and hold the following sequence of buttons:
    iPod 1G to 3G: "REW", "FFW" and "Select"
    iPod 4G+ (includes Photo, Nano, Video, and Mini): "Back" and "Select"
    You will hear an audible chirp sound (3G models and higher) and the Apple logo should appear backwards. You are now in Diagnostic Mode. Navigate the list of tests using "REW" and "FFW". The scroll wheel will not function while in diagnostic mode. For further details on Diagnostic mode can be found at http://www.methodshop.com/mp3/ipodsupport/diagnosticmode/
    Try to do the 5in1, HDD R/W and HDD scan tests. Some successful cases have been reported after the running the few tests under the Diagnostic mode. In case it does not work in your case, and the scan tests reports show some errors then it proves your iPod has a hardware problem and it needs a repairing service.
    B. Format your iPod with a start disk
    I have not tried this solution myself, I heard that there were few successful cases that the users managed to get their iPod (you must put your iPod in disk mode before connecting with a computer) mounted by the computer, which was booted by a system startup disk. For Mac, you can use the Disk Utility (on the Tiger OS system disk), for PC user, you can use the window OS system disk. Try to find a way to reformat your iPod, again it does not matter which format (FAT32, NTFS or HFS+) you choose, the key is to erase the corrupted system files on the iPod. Then eject your iPod and do a Reset to switch out from Disk Mode. Reboot your computer at the normal way, connect your iPod back with it, open the iPod updater, and hopefully your iPod will appear there for the Restore.
    If none of these steps address the issue, your iPod may need to be repaired.
    Consider setting up a mail-in repair for your iPod http://depot.info.apple.com/ipod/
    Or visit your local Apple Retail Store http://www.apple.com/retail/
    In case your iPod is no longer covered by the warranty and you want to find a second repairing company, you can try iPodResQ at your own risk
    http://www.ipodresq.com/index.php
    Just in case that you are at the following situation
    Your iPod warranty is expired
    You don’t want to pay any service charges
    You are prepared to buy a new one
    You can’t accept the re-sell value of your broken iPod
    Rather than leave your iPod as paper-weight or throw it away.
    You can try the following, but again, only do it as your last resort and at your own risk.
    Warning ! – It may or may not manage to solve your problem, and with a risk that you may further damage your iPod, which end up as an expensive paper weight or you need to pay more higher repairing cost. Therefore, please re-consider again whether you want to try the next level

    1. . Disconnecting the Hard Drive and battery inside the iPod – Warning !! Your iPod warranty will be waived once you open the iPod.
    In Hong Kong there are some electronic shops offering an iPod service for Sad iPod, the first thing they do is to open up the iPod’s case and disconnecting the battery and the Hard Drive from the main board of the iPod. Wait for 5-10 minutes and reconnecting them back. The reason behind which I can think of is to do a fully reset of a processor of the iPod. In case you want do it itself and you believe that you are good on fixing the electronics devices and have experience to deal with small bits of electronic parts, then you can read the following of how to open the iPod case for battery replacement (with pictures)
    http://www.kokopellimusic.us/KM_instructions.htm
    Have I tried this myself? No, I am afraid to do it myself as I am squeamish about tinkering inside electronic devices, I have few experiences that either I broke the parts (which are normally tiny or fragile) or failed to put the parts back to the main case. Therefore, I agree with suggestion to have it fixed by a Pro.

    iTunes never displays the iPod in the left pane?
    iTunes is shipped with a "helper application" called the "iPod Service" that runs and is used by iTunes to communicate with the iPod device. This service may be disabled.
    If your system is Microsoft Windows XP and you are logged in as an Administrator:
    1. Quit iTunes and, if your iPod is currently connected to your computer, safely remove it using the system tray application to manage removable devices.
    2. Right click on "My Computer"
    3. Select "Manage"
    4. In the "Computer Management" window, left pane (tree view), follow this path:
    +Computer Management (local) > Services and Applications > Services+.
    5. In the right pane, scroll down to "iPod Service" and double click it.
    6. If the service is listed as "Disabled" and "Stopped," change to "Manual" and "Start" it. ("Manual" will cause it to start when iTunes starts and "Start" starts the service right now.)
    7. Close "Computer Management"
    8. Restart iTunes and wait for it to completely come up.
    9. Reconnect your iPod.

  • I have purchased music from itunes on my iphone and it won't show up in my Ipod music library on my phone.  It shows up in my itunes library on my computer.  This is a recent glitch as up until this week purchased music downloads fine on phone.

    I purchased music on itunes on my iphone and the songs won't show up in my music library on the phone.  They are on my computer itunes library but it won't let me transfer the purchases back to my phone (which I have never had to do before).  Never had this problem before this week when purchasing music on my iphone.
    My Itunes library on my laptop is slightly different from my Iphone library so I don't want to erase and sync the entire library.

    In iTunes, try signing out of your Apple ID & then back in: click on iTunes Store on the left sidebar of iTunes, click on your Apple ID on the top right, sign out, sign back in.  Then try to sync your purchased music to your phone again.

  • My iPod won't show up on my computer or iTunes

    I have a major problem. I just bought a new 4GB 3rd gen nano from Hastings. It charges fine and there are no problems, except one. It won't show up on iTunes (I have the latest version) and I checked My Computer, and it doesn't show up there either. I tried reseting it and everyting, and I reinstalled iTunes, and I restarted my computer. But nothing works.
    It might help to know that this isn't my fist iPod, I also had a 1st gen nano, bu it got messed up.

    When I connect my 2nd Generation iPod touch to my laptop it will not appear in iTunes. It does, however, appear in my Computer.
    I have worked through all of the troubleshooting guides on the Apple Support section, and have uninstalled and reinstalled iTunes twice.
    This message appears every time I plug my iPod in, and frequently whilst it is still plugged in charging:
    'MobileMe Service has stopped working.' This is a pop-up window produced by Windows, I know this is the 'service' that picks up an iPod's prescence but stopping and restarting the service does nothing. My iPod still won't show up.
    Please help, I am willing to faff around a bit. Might it be a problem with Windows itself? If so, how would I go about fixing it?
    Thanks in advance,
    P.S I have the latest version of iTunes, and the operating system of my iPod is 4.2.1.
    My version of Windows Vista is 32-bit.
