I have windows xp and ubuntu and I'd like to add vista to the mix. First I will back up all my files I have from each, then I'm not sure how to go. I'm going to try to use ubuntu's gpart to reduce the size of the xp partition so vista will fit. Then I will install vista. How do I make sure that grub see's that vista is there so that i can boot from it? Is this full of aidz and fail?
