My hand has now been forced. My Windows Vista has crapped out on me. Its so screwed up its now asking for the installation disk before it will restart. I can use a laptop to Skype for now (fortunately) but if I get an installation disk can I go for a later Windows package? Or because its screwed up do I have to reboot it with another Windows Vista installation disk? I don't actually have one so its gonna cost me either way.
