“Does anyone know if there’s a easy way out if something goes wrong with the Win 10 install (such as a restore point)?”
All I know is, that you’ve completed the install, you can automatically downgrade to 8.1. With Win7 your out of luck.
Win10 does have rollback restore points, but then again if your talking incomplete install, with a mess on your hands, then reinstall your original Win7/8.1
Thanks!
