    Partition Editor cannot see partitions on 1 of my 2 hdds

    I originally had an Ubuntu 8.10 beta/Vista dual boot with grub

    I decided to drop vista for xp, no problems

    now, I'm trying to reinstall grub (with no success)

    Code:
    grub> find /boot/grub/stage1
    find /boot/grub/stage1
     (hd0,5)
    grub> root (hd0,5)
    root (hd0,5)
    grub> setup (hd0)
    setup (hd0)
     Checking if "/boot/grub/stage1" exists... yes
     Checking if "/boot/grub/stage2" exists... yes
     Checking if "/boot/grub/e2fs_stage1_5" exists... yes
     Running "embed /boot/grub/e2fs_stage1_5 (hd0)"...  16 sectors are embedded.
    succeeded
     Running "install /boot/grub/stage1 (hd0) (hd0)1+16 p (hd0,5)/boot/grub/stage2 /boot/grub/menu.lst"... failed
    
    Error 22: No such partition
    grub>
    so, I decided to install the new version (8.10)

    boot into the live cd, run install script, and when the partition editor loads, it shows nothing on my first hdd (internal laptop, this hdd has a few partitions: windows, two for data, etc...) when I reboot, windows loads fine and everything is still where it should be...
    (second internal hdd partitions show up fine)

    I have tried the 64 bit version, 32 bit, as well as the 8.10 beta that I had installed before the windows xp install..



    EDIT: Solved it shortly after last post. Thanks Very Much, and sorry for taking so long to get back. College kicked in, and I got Very busy (almost too busy for video games

    Re: Partition Editor cannot see partitions on 1 of my 2 hdds

    Based on your HDD's symptoms, most likely you have a corrupted partition table. From your Live CD, how about posting:
    Code:
    sudo fdisk -l
    Then make sure the Universe repository is enabled in System > Admin > Software Sources, and download and run testdisk with the following commands:
    Code:
    sudo apt-get install testdisk
    sudo testdisk
    After starting testdisk with the above command, choose "no log", select HDD and "proceed", "Intel", "Analyze", and see what it shows for your HDD and what errors it might give. Please post the output of that screen. Then do "proceed", Y/N depending on if you have any Vista partitions, hit enter, and select "search!" so it does a deeper search, which could take a while. Post the output of that screen too, and with all the above data, we should be able to tell if you have a problem with your partition table.

    Unfortunately it looks like my suspicions were correct; you definitely have some problems with your partition table. Once you are done with the deep search we can try to piece it back to together, as it looks like it shouldn't be a problem.

    OK, on that last screen you posted, press "enter" to proceed, then select the "search!" so testdisk does its deep search, which will take a while. Please post the output of that screen.

    Re: Partition Editor cannot see partitions on 1 of my 2 hdds

    OK, I think I have your partition table figured out, but there is one ambiguity that I need to ask you about: did you have a swap partition, or did you delete it? If you had a swap partition, then I believe your partitions should be marked as I have below:
    Code:
    Disk /dev/sda - 250 GB / 232 GiB - CHS 30402 255 63
         Partition               Start        End    Size in sectors
    D FAT16 >32M               0   1  1    10 254 63     176652 [DellUtility]
    D FAT32 LBA               11   0  1  4188 254 63   67119570 [NO NAME]
    P HPFS - NTFS             11  23 13  1316 129 29   20971520 [RECOVERY]
    D HPFS - NTFS           1316 129 30 19581 194  5  293431296
    * HPFS - NTFS           1317   0  1 19581 254 63  293427225
    L Linux                19582   1  1 23228 254 63   58588992
    D Linux                19582   2  1 23474 254 56   62540912
    L Linux Swap           23229   1  1 23474 254 40    3951904
    P HPFS - NTFS          23475   1  1 30073 254 63  106012872 [Uber1]

    The way you can probably find out for sure is to select that first Linux entry above that's in red, and press "p" to list its root directory. If that works, then I think the above partition table changes are most likely correct. If testdisk gives you an error though when you try and list the directory, then instead select the second linux partition in red above, and try "p" again to list its directory. If that works instead, you should mark that partition as "L" and the previous linux partition as "D", and also mark the swap partition as "D".

    Once you have all the above partitions marked correctly, then press enter, and on the next screen I think it should give you an option to "write" the new partition table. Once you do that, reboot, and you might have to do the same Grub steps you did in your original post to reinstall Grub. If you have any problems, be sure to post the new output of (after rebooting):
    Code:
    sudo fdisk -l
    And we can work from there.

    Re: Partition Editor cannot see partitions on 1 of my 2 hdds

    ok, so I did what you suggested, and now I have ubuntu installed...

    but, now it shows my windows partition as unformatted/not there...

    at grub it still shows windows xp, but when I try to load, windows gives an error (can't find something)..so, grub is fine, now the windows partition is mussed...

    Are you sure you marked the partitions as I recommended in my last post? You have to use the up/down arrow keys to first select a partition, and then use the right/left arrow keys to change whether it is marked "D", "P", "*", or "L" like I showed in my last post. Unfortunately your partition table above doesn't look anything like what I suggested in my last post, except for the linux partition which is right. If you haven't written any data to the disk in the partitions other than the linux partition, you might be able to use testdisk again to do the deep search and find the partitions you showed in post #7. If you can get that far, I would try marking them as given in my last post, because I think that is your correct partition table. Let me know how it goes or if you run into problems again.
