Mattdinihas posed an interesting question on Ask Metafilter. He asked whether Windows Vista and XP Pro can be dual booted if they are installed on separate hard drives.

Mattdini recently bought a Toshiba Satellite A135-S4487 which came with two hard drives and Vista home included. Although he doesn’t wish to get rid of Vista, he wants to install and use XP as well. Can he install Vista on the second hard drive and use the BIOS set up to switch between the two?

Disillusioned is apparently already doing this and others agree that it is possible, so if you want to read more about how this is done or share your experiences, follow this link to the forum.
