Heres some context. The computer has Ubuntu 19.04 installed on it. I wiped the recovery drive (stupidly) and windows is completely gone. So any solutions involving windows are out. Including flashing the bios, because acer only provides a windows supported bios (.exe). Anyway, once I enter the password incorrectly 3 times, I get this message: PressingF2, Del, nor any other key during boot changes anything. I've tried every single key on the keyboard, one at a time, deligently. I'm at a loss. I'm confident there are no failed parts. I believe this is a software problem with the BIOS.Answers JackE ACE Posts: 43,730 Trailblazer. October 2017. Press & hold the power button till the machine shuts off. About 5 seconds. Press the power button once to turn the machine back on and immediately start tapping the F2 key. Don't wait for the ACER logo screen to appear. Report back.
