I had harvested a Seagate momentus 5400.6 500gb internal drive from a laptop being tossed in the garbage. My wifes Dell optiplex 960's hard-drive stopped responding after she had done several hard shutdowns (while I was away at work), after several weeks of crashes and startup repairs. The windows 10 64 bit recovery disc couldn't repair this humpty dumpty.
So I plugged into another desktop and using EaseUS partition Master (Free Edition) I reformated the drive converted it to a basic GPT .
My question is if I unplug this drive and install it into the Optiplex will it be able to accept an installation of the original windows 7 OS? I wouldn't think so there isn't even an OS.
So ... How or what do I need to do to get an Operating System Win 10 , installed?
