the hard drive used to boot fine until the day i tried adding a second seagate barracuda (500gb) drive. I plugged it in, turned on the computer and the boot would stall at a blank black screen.
I took the new drive out,(so it should have been back to normal) rebooted and then kept getting an error about not finding a boot device. It was listed in the BIOS but all the values were zero.
now im trying to recover my data off of that original drive and reinstall windows on a new hard drive.
