thanks for replay @DeathBringer now i am out of city i replay u when rech at office

Hi @DeathBringer I am trying to send you a PM to see if you could be so kind as to help me out. I've locked out my Surface Pro Bios, stupidly enough I've forgotten my Bios password. I still have access to Windows if that helps?
Thanks!

Can you run Read Universal in EFI shell?

I dont think so, as i cant boot from any USB device. They are all disabled meh :(

Can you disconnect main drive and connect it to other system?

I would have to dismantle the surface pro. Not sure if that would be ideal, as I would probably not be able to put it back together :(

You have two ways:
1. Replace bootx64.efi in EFI partition (mount it by diskpart).
2. Replace the firmware in BIOS chip by a hardware programmer.

Ok and im guessing to do #1 - I would have to dismantle and remove the hdd? Thank you!

Show screenshot of results in diskpart:
list volume

Sorry for the delay, can you see the attached photo?

Good.
Now do commands:
sel vol 1
assign letter=x
exit
x:
dir
Make a screenshot.

Tried but its not allowing me into the drive partition. Also tried cmd (takeown /F X: /a /r /d y) comes back with user does not have administrative privilages... mehh :(
