I am going to hijack this thread since I have a similar type question. I want to format my hard drive but the problem I am having is this. I bought the computer when Windows Vista was out. I upgraded to Windows 7 with an upgrade disc. I have made a recovery disc. Does the recovery partition on the HD actually have Windows Vista on it? I need that installed before I can re-install Windows 7. Discs no longer come with the purchase of a new computer.
