Spare yourself the misery. Put W-XP by itself on a used $250 box and install Ubuntu
on a frisky INTEL quad. Dual boots are *itches and you will get what you deserve for such byteboy folly. Usrland enjoys pure *nix.
I have a system with Unbuto linux, how can I also install Windows XP pro on the same drive?
I can't say for a Windows/Ubuntu dual boot, but my Macbook Pro dual boots OSX/Ubuntu great. Apple's Boot Camp didn't work worth sh*t for me, but rEFIt's EFI firmware edit and some root level manual partitioning have made dual booting a cinch. I feel like a lot of it comes down to getting your disk partitioning right.
