Linux Mint Forums

I run XP on one hard drive and Mint on the other. Both are normal installations, I just had to make certain that I didn't have the Mint MBR on the XP drive.

When the BIOS boots, I press F8 and I get a menu to select which hard drive or DVD drive I want to boot from. Some motherboards need F11 pressed.

Have no problems with this.

Hope this helps.

Are both disks internal?
Then it should just work - unless you install Win after Linux
It can be something with grub and we have a good wiki for that

Error 21 indicates to me that somehow you may have ended up in UUID hell

but as Mint from Daryna does not use UUID in grub I doubt it - but if it is Celena or earlier....
Please post you /boot/grub/menu.lst as this file is at the center of this

Take a look at my post here and see if that sorts you out.

atlef.

I think I now see the error here

XP is installed on hd0 and I installed Mint on hd2.

Nope!
This is the grub way, but you should have (hd0) = sda and (hd1) = sdb
Grub should be in the MBR of (hd0) if you want to do it the simplest way
Following the grub wiki
http://www.linuxmint.com/wiki/index.php ... _your_grub
you should have (probably)
grub> root (hd1,1)
and
grub> setup (hd0)
Grub is hard to understand
I think you failure earlier can be explained along these lines
