    Red face [SOLVED] HELP! 8.04 install partition does not exist

    I have a P4 standard desktop with Win XP and Ubuntu 7.10. When I boot I get the choice of booting up in Ubuntu or Windows. I wanted to upgrade to 8.04, so I choose the 10 Gb Ubuntu partition that had 7.10 installed on it. Everything seemed to go well. But now when I reboot I get the message:
    Error 22: No such partition

    I can't get into Linux or Windows! It won't recognize any partition.

    I desperately need help. Please tell me there's a solution to this which involves getting my Windows XP back.

    Hopefully, your Windows partition is still there, and there's been a mixup when the installer installed grub. First step is to see what's on the hard disc. Boot up with the live cd and go to Applications > Accessories > Terminal. Post the output of:

    Code:
    sudo fdisk -l
    That's a lower-case L, not one.

    I get the following. Keep in mind I'm on my laptop so I'm actually retyping everything I see in the terminal window.

    Re: HELP! 8.04 install partition does not exist

    With the Live CD when I go to Places I can see my Win XP drive. Everything seems to be there. So, I didn't lose the data. How can I get the boot to work again?

    My apologies; I should have pointed out that if you were able to connect to the internet in the live environment you would have been able to copy and paste from the terminal. Anyway, I'm slightly perplexed about the partition layout. let me give you my thoughts and then take it from there.

    This is the first disc. What is odd is that the NTFS partition is on a logical partition (sda5). Is that your Windows C: partition? Because that's very odd. Normally, Windows can't boot from a logical partition and you have to do some clever hacking to get it to do so. If that is your Windows C: partition, it would have been more straightforward to have sda1 as an ordinary primary partition. Also, the numbers for sda1 and sda5 don't seem to fit. sda1, as an extended partition, is the 'container' for sda5.

    I think you've mistranscribed sda for sdb in the second block. I'm guessing that's all the second disc - sdb. What's interesting is that you've got two ext3 Linux partitions. Did you have a separate /home? If not, it's possible you've ended up with two Ubuntu installations, 7.10 and 8.04.

    You'll have to give me time. I'm also trying to help a neighbour who's been taken ill.

    Question: are you able to connect to the internet with the live CD? The reason I ask is that I think this is a simple grub repair job, but to get the information needed it might be easier to post a couple of screenshots from the GUI. I'll tell you what when you answer that.

    Re: HELP! 8.04 install partition does not exist



    The same happened to me with 8.04! Two weeks of angst!!!

    Running with the Live CD I was able to edit GRUB's Menu.lst and noted the references were to HD1.. Changed them to HD0 and voila!! Happy again.

    This *might* be your problem.... ?

    Re: HELP! 8.04 install partition does not exist

    The first disk listed is my 200 Gb HD and not the Windows: C drive.

    The second disk is my 80 Gb HD and yes that is my Windows: C drive.

    I did mistranscribe sda for sdb.

    I can connect to the internet from the Live CD. It took me a couple of hours but I finally figured it out.

    Re: HELP! 8.04 install partition does not exist

    There is a quick way to get Windows back, but it won't let you boot Linux for the time being:
    Code:
    sudo dd if=/dev/zero of=/dev/sda bs=446 count=1
    Keep in mind if you mistype it it could very well wreck your data, so be careful.
    The DOS command
    Code:
    FDISK /MBR
    will do the same thing.

    First, though, to get into the menu.lst from the live CD, mount the partition you installed Ubuntu to (Places menu), then find boot/grub/menu.lst and edit it as root. You might need to press Alt+F2 and run "gksu gedit", then use File>Open.

    Re: HELP! 8.04 install partition does not exist

    So, if I type the code: sudo dd if=/dev/zero of=/dev/sda bs=446 count=1 (how do you get that niffty box around the code quote).

    I'll get my windows back but not Linux.

    You also state FDISK /MBR is a DOS command and will do the same thing. But if I can't get windows up how can I enter the DOS command?

    I don't understand what you mean by edit the boot/grub/menu.lst as root. I found the file and just double clicked on it and it opened in a text file, but I don't know what I'm editing and what will it do? Must I do this before I perform the code you listed above?
