Realistically the only way to get around a CMOS password is to wipe the BIOS back to its default settings. Turn off the power and unplug the cord, then hold the power button down for 10 seconds. Once that is done, open up your computer and look for a Clear CMOS jumper, most new motherboards have it. It should look like 3 pins with a little black sleeve over 2 of the pins, and will probably be located near the BIOS chip. Take the black sleeve and move it to cover the middle pin and the uncovered pin. Once that is done you can restart your PC and it should inform you that the CMOS defaults have been loaded. Once you are sure the password is gone reset the jumper so you don’t loose the settings everytime you boot up.
Once the CMOS settings have changed if you find you can’t load Windows go into the settings and check the boot device order.
If you can’t see the jumpers, look for the CMOS battery, it’s a flat round silver battery. Take this out and wait 5 mins then start the PC and it should give you the same message that the defaults have been loaded.
If resetting to defaults doesn’t help you then take it to a professional to have the BIOS flashed.
