If you want to keep the raid0 setup then ongte
is right, linux will not see the drive. What you can do is the same thing I did, I have win-xp on a raid0 so I installed Debian to a 3rd drive, and installed the Grub boot loader to that (3rd) drive. After everything was done I went into the Debian OS and edited the grub menu.lst and added a entry like so
###title=XP originally in (hd1)
title Windows XP
map (hd1) (hd0)
map (hd0) (hd1)
You will map win-xp to the first drive of the raid0 setup. After this reboot and go into the bios and set the 3rd HD to be first in boot order, save and exit. Now when you boot, the system will boot to the linux drive and grub will let you chose which OS you want.
