he had vista, he upgraded, to windows 7 premium, he only has the windows 7 upgrade box now with code and 32/64bit disks. can he install this without his old vista cd or code which he lost, I was thinking since he had previoiusly done the upgrade on the vista, it deactivates his vista code and the windows 7 upgrade codes is the only one he needs, however can he use thes disks on a new ssd or does he need a vista disk, will it work without the vista code? last thing, I have a old vista box I had used, 32 bit only, if he needs a vista disk / code can he use mine, with that already used windows 7 upgrade.. darn im confused.
