    Default Dual booting BT4 and Ubuntu 9.10

    I have install BT4, ubuntu 9.10, and XP PRO, on one Hard drive.
    The problem is, when I installed BT4, it updated the GRUB and now it will not let me boot back into ubuntu 9.10 (it says error 15, file not found, press any key to continue)
    I can still boot into XP though, I'm pretty sure all I need to do is go into BT4, and modify the GRUB?
    any thoughts?

    Thumbs up

    you can use grub manually from the command line when you see the splash screen press c. that will take you to grubs command line. then if you know what partition you have what on you can do the following to boot backtrack.

    grub> root (hd0,0) #if its on your first hdd if not (hd0,1) etc
    grub> kernel /vmlinuz root=/dev/sda3 rw vga=0x317 #use your partition
    grub> initrd /initrd.gz
    grub> boot

    if you not sure use find stage1 and play around with different partitions.

    You should probably be asking this at the Ubuntu forums...
    Capitalisation is important. It's the difference between "Helping your brother Jack off a horse" and "Helping your brother jack off a horse".

    The Forum Rules, Forum FAQ and the BackTrack Wiki... learn them, love them, live them.

    I have they've got nothing so far. I was able to get back into ubuntu 9.10, by reinstalling GRUB via, LIVE CD. But now I can't see BT4, or XP Pro.
    I'll post if I find the anwser

    You can get into any operating system you have installed via the directions i already gave you. i suggest you go read "man grub".
