How do i bypass the primary drive lock password

On the mainboard near the coin battery you'll find a jumper. take it off and reboot. Replace it and reboot again. that works sometimes. If not you can go to the motherboards' BIOS like Phoenix and they have backdoors built in. Read on:
Backdoor passwords Many BIOS manufacturers have provided backdoor passwords that can be used to access the BIOS setup in the event you have lost your password. These passwords are case sensitive, so you may wish to try a variety of combinations. Keep in mind that the key associated to "_" in the US keyboard corresponds to "?" in some European keyboards. Laptops typically have better BIOS security than desktop systems, and we are not aware of any backdoor passwords that will work with name brand laptops.
WARNING: Some BIOS configurations will lock you out of the system completely if you type in an incorrect password more than 3 times. Read your manufacturers documentation for the BIOS setting before you begin typing in passwords

If you happen to forgot windows logon password, you can get into safe mode (F8 when booting up) to reset windows password when you forgot user account password, but when you forgot admin password, there's no way to change it, you should use a software application to recover admin password. A week ago, I forgot my Windows admin password. Last, I used Windows Password Seeker to reset the Windows password successfully. It's worth trying.

When I lost my windows password, I like to reset Windows Password with Windows Password Reset 9.0 and I think it is excellent and professional! Once the password is removed, there is no need to type any passwords but to leave it blank, and click the user name to instantly log on Windows.
