Hey everyone I ran into a massive problem today. My cousins laptop died on her so I plugged the hard drive into my computer to save same of her files for her after I unplugged the drive my computer will no longer boot. I pretty much get a windows error 0xc00021a. I tried a couple of things I found on the net but nothing seems to work. The windows 10 troubleshooter that comes up after the failed boot won't even let me reset. Any help would be greatly appreciated thanks.
