[conspire] Help with GRUB

[Tony Godshall]

1. Boot from a liveCD (e.g. Ubuntu or SystemRescueCD)

2. mount / (and /boot if any) manually

3. grub
4. root (hd0,0)      (assuming /boot is in drive 0 partition 0)
5  setup (hd0)      (assuming you are booting off drive 0)
6. quit

7 sync&&sync&&sync&&shutdown -r now
8. remove livecd once drives have been unmounted

The above has worked for me many times.  you'll have to adjust hd0 and hd0,0
to something else if your linux partition is not on the first drive or not
on the first partition.  You'll probably want to check the contents of
/boot/grub/menu.lst too before you start grub

Best Regards.
