well i have vista and i installed xp. the problem is i cant dual boot them. i did the whole reinstall the vista boot mbr but it didn't fix the problem and i still cant get into vista to fix the boot mbr settings. when i start up it just gives me a boot menu (because i had to reinstall vista and it gave me an old windows options) and gives me two xp's (it basically masked the old windows boot as xp) but there is no vista. i cant get back into it. does anyone have any idea whats going on?
