I have a desktop computer that has unfortunately become corrupted. Further, I can't find the recovery disk I once made. This PC runs Windows 7 Home edition 64-bit. I figured the best choice would be to run a Windows 8 upgrade while the price is right.
The question I have is this: when I attempt the upgrade, does the previous Windows version, the one I am upgrading from, need to be running, or can I boot from the install disc, entering the product code when prompted? Thanks.
