I did a clan install of W 7 64 bit from 32 bit and it works well apart from boot up. The OS is definitely on c drive and there is a file for old windows. However there are three program files, one for windows 7, one entitled program files (x86) and another program files (x86) (x86). When I boot up I am asked to choose W 7 orVvista but both options load W 7 . Can anyone advise me if I should re-install W 7 or not please ?
