    Installed Vista, now i cant boot up Ubuntu

    had Ubuntu Server. 8.10. first. then i installed Vista Home Prem.
    i followed the steps using NeoGrub.

    I noticed my menu.lst has this line

    title Ubuntu 8.10, kernel 2.6.27-9-server
    uuid 6a88bdf8-cb8f-470d-8698-02522703a087
    kernel /boot/vmlinuz-2.6.27-9-server root=UUID=6a88bdf8-cb8f-470d-8698-02522703a087 ro quiet splash vga=0x346
    initrd /boot/initrd.img-2.6.27-9-server


    but i read seomwhere it should be

    title Ubuntu 8.10, kernel 2.6.27-9-server
    root (hd0,1)
    kernel /boot/vmlinuz-2.6.27-9-server root=UUID=6a88bdf8-cb8f-470d-8698-02522703a087 ro quiet splash vga=0x346
    initrd /boot/initrd.img-2.6.27-9-server

    why does it say uuid. and how can i chnage it back. I figure i can just edit and type it in. I treid that but then on boot up it tells me.

    Cant mount drive.

    If i leave the line as it is. (with uuid) then i get

    error 17 file missing.

    how can i find out which combination of (hd0,1) to use? im currently using a live CD to boot up and view my server files.

    Re: Installed Vista, now i cant boot up Ubuntu

    Well first, I would expect your Grub-bootsector has been overwritten, which is why you normally install the other way around, first Win, the linux.
    But maybe MS changed it's policy concerning other OS on the same HardDisk. Because I would expect Grub to not show up at all.

    Using the live cd you can identify the UUID of your linux partition (depending on your setup this should be the start partition) by
    Code:
    ls -l /dev/disk/by-uuid
    The syntax of grub is (I believe...) hd(harddirve,partition) where first harddrive/partition is refered to as 0.
    So using gparted in the live Cd should enable you to figure out which partition/UUID to use.
    Also, if your boot sector is damaged you might download "SuperGrubDisc" (burn iso to cd and boot using it) to repaire it.

    It's been a while since I had to cope with this, so my memory is a bit hazy, but I hope I could help.

    thats what i ger when using

    ls -l /dev/disk/by-uuid

    and pretty much lsot after that lol.

    Re: Installed Vista, now i cant boot up Ubuntu

    Use
    Code:
    sudo fdisk -l
    to identifiy which partition is your linux system. You will get something like
    Code:
    sudo fdisk -l
    [sudo] password for jens:
    
    Platte /dev/sda: 100.0 GByte, 100030242816 Byte
    255 Köpfe, 63 Sektoren/Spuren, 12161 Zylinder
    Einheiten = Zylinder von 16065 × 512 = 8225280 Bytes
    Disk identifier: 0xcccdcccd
    
       Gerät  boot.     Anfang        Ende     Blöcke   Id  System
    /dev/sda1   *           1        4462    35840000+  83  Linux
    /dev/sda2            4463       10636    49592655   83  Linux
    /dev/sda3           10637       12008    11020590   83  Linux
    /dev/sda4           12009       12161     1228972+  82  Linux Swap / Solaris
    Then you should be able to seperate which are Win and which are linux partitions. I don't know how you setup your partitions, so ...
    With the other command you should then be able to assign the right uuid

    Re: Installed Vista, now i cant boot up Ubuntu

    ok so i did fdisk.

    now i have both info so i put it like this?

    title Ubuntu 8.10, kernel 2.6.27-9-server
    root (hd0,1)
    uuid 6a88bdf8-cb8f-470d-8698-02522703a087
    kernel /boot/vmlinuz-2.6.27-9-server root=UUID=6a88bdf8-cb8f-470d-8698-02522703a087 ro quiet splash vga=0x346
    initrd /boot/initrd.img-2.6.27-9-server

    Re: Installed Vista, now i cant boot up Ubuntu

    Sorry, I am really not sure here, but I believe UUID is an alternative to hd(0,1). Both are ways to identify any partition in your system, so.. If your linux system partition still exists and it is indeed sdb1? then your grub entry should be correct, which would point to a damaged boot sector - at least winxp does kill your bootsector if you install it after linux, so actually what you need to do is repaire the boot sector using "SuperGrubDisc" or a simular tool.
    However, maby somebody else could give advice here, cause as I said I am a littel unsure about all this.

    Maby this post can help...
    http://ubuntuforums.org/showthread.php?t=442945
    or
    http://www.3till7.net/2007/10/25/grub-error-17/

    It seems the win install did something so linux doesn't recognize the partition type. sorry, never had this error myself.

    Re: Installed Vista, now i cant boot up Ubuntu

    In order to get a clearer picture of your setup related to your boot problem, how about downloading the Boot Info Script to your Ubuntu desktop, open a terminal (Applications > Accessories > Terminal) and do:
    Code:
    sudo bash ~/Desktop/boot_info_script*.sh
    That will create a "RESULTS.txt" file in the same directory from where the script is run, namely your desktop; please copy/paste the contents of that file to your next post, highlight the copied text, and click the pound sign # graphic in the Ubuntu forum message box so that the text will get "code" tags put around it. The results of that script will help clarify your setup and hopefully what your booting problem might be.
