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?
First off if the version of 7 on the old system is OEM it is tied to the other system so moving it is a EULA violation. Even if it its is a retail copy given the differences in the hardware to get 7 working you would need to do a clean reinstall if you want a stable system.
Trying to just move the HDD over has a good chance of just making a mess of things. I would recommend leaving W8 in place on the new machine an running the Easy Transfer. W8 is not without benefits and your friend will get used to it quickly enough.
