Need Help Editing Grub

[Mark Phillips]

kitepilot,

Thanks for the clarification.

Sorry to be such a newbie.....You wrote
grub
root (hd1,0)
root (hd1)
It should answer that it found the stages, verify that there are no errors.
quit

Should it be
grub
root (hd1,4)
root (hd1)
It should answer that it found the stages, verify that there are no errors.
quit

because "find /boot/grub/stage1" returns (hd1,4) and not (hd1,0)? Or,
perhaps it doesn't matter, and grub will do the right thing when I use
(hd1,0)?

Thanks!

Mark
