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
Just do it what I wrote.
when i get to;
x:
Access is denied
Now do commands:
sel vol 1 (ok)
assign letter=x (ok)
exit (ok)
x: Access is Denied
dir
Do in all command line with administrative rights!
duhh!! sorry!
Good. Now do in command line with administrative rights:
bcdedit /enum firmware
Good! Your system can boot from USB with first priority.
1. Take small USB-stick and format it to FAT32
2. Make a folder with name EFI, then inside it make a folder with name Boot
3. Download Read Universal and unpack it.
4. Rename RU.efi to and bootx64.efi copy inside Boot folder.
5. Try to boot from prepared USB-stick.
It skips the USB and goes straight to windows
Ive checked the USB by booting on another PC and it works as it should. appreciate all your help!
Your device supports EFI-booting only. And it doesn’t skip boot from proper USB.
P.S. I think you haven’t this device and you’re just man-in-the-middle real owner and me.
Does the USB need to have a specific name? or a specific RU version?
