I go to system restore, then check the box that says "show more restore points" and I can see the one I want to use at the bottom, called "System Image Restore Point" "Type: Backup" . I select that restore point and click next, then I get a message saying that "The backup drive could not be found. System Restore is looking for restore points on your backup. Make sure the backup drive is on and connected to this computer and then click OK" ...I click OK and then I'm in an infinite loop where I keep getting this message.
My only thoughts are that the drive is password protected, so maybe I'll disable that for now.
