Hi, I'm upgrading my system I have windows 10 on a flash drive and need to reboot my system from an USB drive but that option is greyed out in my bios so I need the bios password. Thanks

Hi,

 

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.

 

If you Contact HP Business support they should be able to send you a customised SMC.bin file which you can use at boot to reset the password.

 

Regards,
