Need Help Editing Grub OOPS! Screw up...

[Mark Phillips]

Kitepilot,

Well, I did this....
grub
root(hd1,4) - got an appropriate message like "found something"
setup(hd1,4) -- got a bunch of messages that looked right - basically
confirming it found everything
quit

Initially, I tried root(hd1,0) and got an error message; also setup (hd1)
and got an error message. BTW root(hd1) also returns an error message. The
commands above were the only ones that worked without errors.

I also change my fstab file as shown earlier (basically changed hdb to hda).
And the menu.lst was changed appropirately - hdb to hda as I posted earlier.

Moved the disk from ide2 to ide1, and installed the new blank disk in ide2.

Booted up, and no boot, just a black screen. I made sure the jumpers were
set for master on ide1 and slave on ide2. ide1 has the linux drive and ide2
has the new blank drive.

Checked the bios to see if both drives are recognized, and they are, and in
the right spots as well.

Currently downloading most recent knoppix image to burn a cd and see what's
up. Any suggestions would be appreciated.

Mark
