I just got my hands on an older PC that was not working. The reason was the HDD was fried. I want to get this PC working and then sell it, but I do not have the recovery CD that came with it. The PC has a legal key on the side of the case. What are my options? Can I use one of my disks to install WinXP OS and use the key on the side? Is that legal? I want the sell it and do not want it to bite me in the ***** later.
