if you dont know your hp elitebook bios password there is a way override it without needing to reset it
if the VT , VT for direct I/O, HT options are disabled in your hp elitebook bios you can still change them by downloading hp performance advisor !
inside hp performance advisor there are then some options that let you change your bios settings without any bios password
In windows 10 your uefi bios settings are no longer accessed via ESC,F1, F2, F10 or F12 instead you need to boot into windows 10 first then click
- windows start (yes its back ! yay!)
- update & security
- advanced start up | restart now
- advanced options
- uefi firmware settings
once you have done all this you should see the UEFI BIOS screen you used to get when pressing F1 etc
You can only install windows xp service pack 2 (wxp sp2) on a SATA HDD if your BIOS lets you change HDD mode to SATA Compatability from SATA AHCI.
If you BIOS doesnt let you do this you have have to use a windows xp service pack 3 (wxp sp3) dvd instead which does support SATA AHCI.
After installing wxp sp2 you can then go back into the BIOS and change the HDD mode back to SATA AHCI
Many thanks to @morgancomputers tech support for explaining this all to me
