I've just helped my buddy replace his troublesome vista with xp on his 2.4Ghz MBP (i own original discs for both systems so the problem should not be because of using special 'hacked' versions of xp). Everything was all good until we restarted the system. OSX was gone, and Windows was on a strange partition of 127GB, when it was supposed to be on about 60GB of a 200GB drive. Now we cant even see the other missing space when we run XP or Vista setup again. He has lots of college work in there, so we're holding off from reinstalling OSX for now unless there really is no more hope. All opinions and advice appreciated. Many thanks.
