Having trouble with a laptop? Is your windows corrupted? Buy a 2.5″ USB 2.0 HDD case, pull your hard drive out of your laptop, plug it into your case, and plug the case into your desktop or another PC. You can then usually get your data off your PC, and back it up before reformatting your hard drive and installing the new operating system.
I’ve linked above a $50 case for this – I bought the CompUSA store brand for $20. Good luck, and happy ticking….
