I'm wanting to set up a quad-boot system. ATM, I have both the 32 & 64 bit versions of XP, but I also want to try both 32 & 64 bit versions of Kubuntu. I know Grub ought to handle 1 lot of Linux along with both XPs, but I've heard it won't handle 2 lots of Linux for some reason.

It was suggested to me that I try
EasyBCD, which would supposedly do all I want & more, but unfortunately it appears to require Vista, which I'm not in any hurry to try.
