now i cant get xp to boot....or anything...
lucky you !... but seriously... are you SURE you didnt remove the XP partiton ?
without more info or a detailed description i can only guess you wriote over the windows MBR with Grub, but didnt confuigure grub to boot windows...
boot the windowsXP cd and when asked, enter rescue mode and use "fixmbr" to return the windows MBR (master boot record) to its origonal state.
