I recently set up a dual boot with windows 10 and elementary OS everything was going ok and the install process was completed. but after this the computer became useless. I cannot see anything except for the menu bar and none of the icons works. I shut down the computer but it doesn't even boot properly. It goes straight into the faulty installation where nothing works. I have no way of getting into the bios and I try alt+sysRq +... and nothing is responsive.
