Hi, I was using Windows 8 after then I installed Ubuntu 14.04. It is running fine. Then I planned to install windows 8.1. I make bootable pendrive using Winusb (Ubuntu application). When I boot into pendrive, Windows 8.1 logo appear then BSOD (Blue Screen Of Death) with error DRIVER_VIOLATION. Then It restarts.
I am able to boot into Ubuntu 14.04, Bios.
