hard drive not bootable

Today I changed the hard drive in my PC to one from my broken laptop and i could not remember the password so I started to reset the hard drive when it got unpluged. So instead of continuing to reset it I put my old HD back in and when I started up it said no bootable device... Please help

The one from my laptop is done reseting and the old 1 still wont work

The ok hard drive works in another pc
