I have a dual-boot PC with XP and Fedora Linux, on separate hard drives. I would like to be able to boot up either one individually, but I don't really understand the boot process.

GRUB is on the 2nd drive, but if I need to remove that drive (or if it goes bad) I still want to be able to boot the 1st (XP) drive.
I tried removing the 2nd drive, and booting with a GRUB CD. At the grub prompt I typed in:

rootnoverify (hd0,0)
chainloader +1

That is from my working grub.conf file on the 2nd drive.
Nothing happens.
What am I missing?

command line needs one tiny more command
boot

see my signature if you get into further troubles...I hope not

I prefer

grub
root (hd0,0).....grub should respond with a fat
chainloader +1
makeactive
boot

makeactive may not be required as your msdos style mbr should already have the bootable flag but what the heck no harm in using it......good luck

Those are the magic words, aus9.
It's a relief to know that I can still run one of the drives if the other one fails.
Thank you!

umm, please test it rather than trusing my word

I did run those commands, aus9.
You were right about makeactive, it wasn't necessary.
Also I can use: root (hd0,0) instead of rootnoverify,
it works either way.
Thanks for your help.
