Bought a new hard drive because my old one was busted, in the meantime, I used my notebook's HD with windows 8.1 on the PC and it worked fine. When the new HD arrived I installed Windows 10 on it, but when doing it I had the notebook's HD connected as well to transfer all of its files. So now on the BIOS it shows that the notebook's HD was the Windows boot manager. When I started the computer it showed that I could select any of the OSs to run. When I wanted my notebook back I disconnected its HD, put it back on the notebook and tried to turn on both the PCs. In the notebook, it gave me a blue screen and something saying that it wasn't possible to boot because it needed something else. On the desktop, the motherboard didn't even identified the HD. Any way to revert this?
