Okay so im working on a friends computer and he had a HP with a amd A6-3620 and he just bought a new HP with a Intel I5 2320 in it. We are trying to figure out how to put his old hard drive in the new intel pc and have it work but it says no bootable drives detected. Also the new pc is windows 8 and the old amd was windows 7 and we are trying to keep 7. Any ideas how to pull this off?
