Re: 2 HD, Dual Boot Grub Problem

You should be able to use GRUB to boot from another hard drive.

I don't know the exact solution to your problem so I'll just guess:

Try with rootnoverify instead of root.
Try putting the map-switching before the root line.

However this problem has been solved a dozen times in these forums so the correct solution should be around.
