Windows 10: I used a boot device from windows 7 and can't activate windows again.

I bought a used PC from a friend, it had windows 7 installed and after trying to set it up, I can't find or activate windows 10. Everything I have tried to search hasn't helped solve this at all. Not sure what to do.

Windows 7 & XP Boot Problem

I did as that said, and was able to get back into Windows 7, but I did not have the option of going into XP. Response two on that page deals with that and says...

I did all that, upon rebooting Windows XP was listed as an option but selecting it doesn't work. I get a message saying something is missing or corrupt. I'm confused what drive letter I was supposed to use during the quoted method of adding XP support. While in Windows, the drive with XP is labeled as E:, but if I go into Windows setup it says the drive with XP is called C:. I had put E:, so perhaps it was supposed to be C...but while in Windows 7, the Windows 7 drive is called C:.

My current situation is that XP wouldn't work at all, but 7 would. I decided to reinstall XP again to be in the same situation as before. I'm unsure how to get them both working.
