Want to know how to enter the recovery in Acer machines, so you can do a hard factory reset? Here is exactly how to do just that. These key combinations should work on all acer models like the Aspire One. Hold Alt and F10 at the same time right after you hit the power button to turn on your pc, you must act fast while at the Acer logo screen. I usually mix holding it and pressing the keys back and forth to ensure I enter it. You will see a message at bottom of screen that says “Entering eRecovery Mode”, or something similar to that. If you do it right, you should see a screen like the green one in screenshot below. eRecovery Management.
