So my laptop had been working for the past few hours. I leave the room and come back to see the "No bootable device" error. I do all the BIOS default steps with turning off the laptop, turning it on and press f2, f9 and enter, f10 and enter. That doesn't work. The laptop doesn't make any loud noises when it is starting up though. Have had this problem three months ago. I don't want to send the entire laptop to Acer again and would much rather just order the part myself and fix it then.
