If the machine came with Vista pre-installed (OEM copy) and a free upgrade to Windows 7, that OS is tied to the machine and cannot be removed and installed on a different machine.
I am selling my laptop tomorrow and I need to erase the HD. I bought the computer new, however, and it did not come with a software disk. Consequently, I have the windows 7 upgrade disk that was sent to me back in October.
Is there a free or cheap program that erases the HD but keeps the OS?
