Hello, I'm encountering an issue with Windows 8.1 when trying to do a clean install. The OS install boots, but then crashes saying: "Un unexpected error occured. The computer will now restart." I've been thinking this is a driver issue, Wi-Fi card or DVD, both of which I've removed from the laptop, but still the error persists. I've been reading about this error on lots of forums but no solution. Has anyone encountered this and figured out a solution? Currently, I have Ubuntu installed on the laptop. Thank you in advance. EDIT: It once ran Windows 8 without a problem, but the Store update to 8.1 caused the same problem with the installation reverting the settings back to Windows 8.
