    Hi Folks,

    I'm installing 9.10 on a Sony Vaio laptop (pcg-frv31) and am having trouble booting from the hard drive.

    I've installed 9.10 from the CD and it's all 'there' as it were, but when I remove the CD ad reboot, I get 'operating system not found'.

    The problem seems to be along the lines of what's being discussed here, so I have tried all the ideas above, but to no avail.

    1. There doesn't seem to be any protection on the MBR in CMOS.

    2. Originally, /media was empty when I tried listing the contents, so I clicked on the main partition in Places and that mounted it, but when I rebooted, it still can't find the operating system and when I tried 'ls /media' after rebooting, it was empty again. That is, I had to re-mount the filesystem.

    3. The option to label my mount point in GParted is greyed-out in the right-click menu, but I would love to rename it! How can I do it?

    4. There is no device.map in grub. /media/'mountpoint'/boot/grub is empty.


    5. When I reboot to the live CD, all location information is gone, time is wrong, etc. That is, nothing in my proper installation has taken hold.


    6. I have tried to re-install Ubuntu from the CD and, at the partitioning stage, it tells me that Ubuntu is the operating system installed on the partition I am about to reformat, so Ubuntu thinks that Ubuntu is installed.


    The upshot is that 9.10 just isn't installing properly. The CD with the disk image checks out fine.


    Thanks for any help.

    Boot with the cd, Try Ubuntu option, open terminal and execute:
    sudo fdisk -l

    Copy the result here. That's for start.

    It looks like you have running ubuntu. If you want to reinstall grub2 in case it's messed up, boot with the ubuntu cd, Try Ubuntu option, and in terminal execute:

    sudo mount /dev/sda1 /mnt
    sudo grub-install --root-directory=/mnt/ /dev/sda

    That will reinstall it on the MBR of /dev/sda using the mounted /dev/sda1 as root (which is your root partition). Easier then using the /media commands and it gets the same result.
    Reboot without the cd and check if anything has changed.
    If still not working, report what exactly is the problem because you continued another thread and it's difficult to follow what exactly is your problem.

    PS. Note that if ubuntu is the only OS on your computer you will not see grub menu at start. Ubuntu will just start. That's because there is no other OS to select anyway. It should start normally and work.

    Thanks, Darko.

    I've tried re-installing grub. That installed grub, but didn't solve my problem. I've moved my problem to a new thread at http://ubuntuforums.org/showthread.p...70#post8513870 where you can get more detail.

    One of things that's annoying in all this is that it takes 30 minutes for ubuntu to boot from the CD, so every time I try a new idea and then reboot, it means another 30 minutes of waiting! Unless, of course, the problem is fixed, but, alas, so far I haven't achieved those dizzying heights.

    I am very excited about ubuntu, however. Can't wait to get it going!

    Thanks for the help.

    Hey, This post really saved my night, i have been working on getting back to my ubuntu 9.10 system all day since installing XP on a dual boot. I think I inadvertently installed grub2 when I had grub legacy leftover from my 9.04, anyway this method got me back!!! I love it.

    i also have same problem as adonet #18
    Code:

    grub-setup: warn: Attempting to install GRUB to a partition instead of the MBR.  This is a BAD idea.
    grub-setup: warn: Embedding is not possible.  GRUB can only be installed in this setup by using blocklists.  However, blocklists are UNRELIABLE and its use is discouraged.

    Try installing GRUB2 to the MBR of a hard disk instead of to a partition boot sector and see if that works.

    Re: Computer won't boot to 9.10; No Grub Menu

    Please help. This is getting frustrating.
    I have one hard drive and one operating system on that one drive. No dual boot, no raid, no windows, no usb boot. Just 9.10 installed on one 40 gb drive. After trying the various techniques from this forum, I'm now stuck at Grub loading, error, grub rescue prompt. No menu list to choose from or edit (e).
    Here is the output of 'sudo fdisk -l'
    Code:
    ubuntu@ubuntu:~$ sudo fdisk -l
    
    Disk /dev/sda: 40.0 GB, 40000000000 bytes
    255 heads, 63 sectors/track, 4863 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes
    Disk identifier: 0xd0f4738c
    
       Device Boot      Start         End      Blocks   Id  System
    /dev/sda1   *           1        4677    37567971   83  Linux
    /dev/sda2            4678        4863     1494045    5  Extended
    /dev/sda5            4678        4863     1494013+  82  Linux swap / Solaris
    ubuntu@ubuntu:~$
    Tried this (which worked in the past):
    Code:
    sudo mount /dev/sda1 /mnt
    sudo grub-install --root-directory=/mnt/ /dev/sda
    now it gives me this when I try that:
    cp: not writing through dangling symlink `/mnt//boot/grub/gfxterm.mod'
    Never did that before.

    And when I try and reboot it gets stuck at grub loading, can't find file, grub rescue.

    (This started with a spontaneous reboot(don't know why), which of course didn't reboot properly and dumped me at the initramfs prompt)

    Re: Computer won't boot to 9.10; No Grub Menu

    The first thing to do would be to run a file system check.
    If the file system check is able to be completed with no problems you can try to boot, but if it fails with an error message, make a note of the error.

    You can run a file system check by right-clicking on your partition from GParted Partition Editor in your Ubuntu Live CD.
    If you like the command line you may like to use this command,
    Code:
    sudo e2fsck -C0 -p -v -f /dev/sdx,y
    This command will either fix your file system or at least report useful information if it encounters errors which require further investigation.
    The command GParted runs is almost the same and it also reports useful info if you click for the drop-down menus in the file system check dialog box GParted.

    Re: Computer won't boot to 9.10; No Grub Menu

    It's now 2 AM. When I booted with live cd for internet help, I opened my home directory (not the live cd home) to be clear, and it was EMPTY! Perhaps a noob thing, but all my stuff should have been there. EMPTY! So I thought at that point I might as well just do a clean install from fresh. Install went smoothly, applied all updates. When it was finished a reboot was required...wait for it......INITRAMFS!

    I'm beginning to think this is just garbage. Our IBM 8088 downstairs boots up just fine.

    Any ways, I do appreciate the help. This is ridiculous.
