I have a AMD 955 which is 7 1/2 years old and I put Windows 10 on it when it was free on a SSD Hard Drive. I also have Windows 7 on another Hard Drive. I am running Windows 7 and I disconnected the Windows 7 Hard Drive and hook up the Windows 10 Hard drive and the BOIS would not even see the hard drive. When I put back to the Windows 7 Hard drive it tried to boot off of my Data Hard Drive so I had to go back into the BIOS and fix it. My question is the BIOS can not see my Windows 10 Hard Drive from at 7 1/2 year old computer and that Windows 10 needs a motherboard that can boot off of the New BIOS?
