How can I get passed the main password on cpu. If I can't remember

Question

Can't get into cpu. Forgot password

Answer 1

What CPU password? Do you mean BIOS?

Answer 2

Yes I sure do

Answer 3

You can try reset the BIOS by removing and reinserting the CMOS battery. It's a flat button cell. If not available, see if there is a reset button for the BIOS on the motherboard.

Resetting BIOS shouldn't damage your OS.
