As to another copy, the full retail works but let's grind this finely. Microsoft only supplies the OS. The video, wifi, sound and all that may need drivers and a specific install order of drivers to get the machine fully functioning.
Recovery disks are easier.
i had a problem with my flakey hd, to which i posed a question on this forum.
i may end up having to buy another hd, so my question is if i buy an new hd for my brand(vaio) computer, do you think the recovery disk (xp home) will work. if not, will getting another copy of xp home work on the vaio?
