Reset bios password befor entering new os
SOURCE: Bios Password Reset
The only idea I have is to find and disconnect the CMOS back-up battery after removing main battery and unplugging the AC adapter. That SHOULD clear the bios completely, wiping out the password, the date, and everything else.
I know this works on desktops, and most laptops, but no promises, and the cmos battery may not be easy to access.
You should probably leave the battery unhooked for at least 1-2 minutes to be sure it clears.
Hope this is some assistance!
SOURCE: how to reset password
To set the bio password, follow the following:
As soon as your laptop powers up, hold F2 until the ACER logo appears. Now press the right arrow on your keyboard twice to go to the: "MAIN" tab. Now press enter. You will be asked to enter the new password twice along with the original one. (if you previously had a password.). Now scroll down to where it says either: "Enabled" or "Disabled". If it is: "Disabled", press enter and select "Enabled". Exit the BIOS saving changes.
Done.

The laptop password cannot be reset by removing the battery and there is no jumper for the CMOS or bios reset. You must go to Acer to obtain the master password as laptop computers have NVRAM (non-volatile RAM) that retains the password forever as an anti-theft protection. Steve Medley
