I want to boot an OS install from my USB, the bios asks for a password, bought a probook 6475b second hand.

Unfortunately, business machines such as Probooks or Elitebooks have more stringent security than consumer models - they don't produce 'halt codes', the password cannot be derived from the Serial No. and the code is stored in non-volatile memory so removing the RTC cell will not reset the password in this case.
If you still have the sellers contact details, see if they can remember the password.
The only other option would be to Contact HP Business support as they may be able to send you a customised SMC.bin file which you can use at boot to reset the password.

I have tried contacting HP support, and it asks for a product code, when i enter the one on the sticker it doesn't regonize it.
I am stuck on windows 8.1 and I got a multi licence on the OS so I can't upgrade to windows 10.
