I have two emachines and one had the power supply die. So I bought a new one and put it in, but it would not boot. I took the hdd out and put it into the other machine (they are both the same model w2785) it started up and said there was a disk error and the bios settings changed and that I had to do a system restore. So I shut down and put the original hdd back in it. Started it up and the hdd that was running good now did the same thing. I restored the hdd using the system restore disks after instalation it keeps coming up saying disk error do a restore or disk comand promp! It just won't boot. I tried it with both drives, same thing I know that I messed up putting that potentully bad drive in there and hope that I am not out of luck. I looked in the( cmos,cbios ?) but really don't know the settings. Can somone please help me undo my stupid move!
