I replaced my HDD in my HP ProBook 640 G1 with a fresh blank. I forgot my BIOS password & there's no halt code so now I can't get into the BIOS to switch the boot sequence to install an OS. Please help.

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 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.
