HP Elite X2 G4 OS wont boot and cant access recovery because i don't have the BIOS admin password

[Skittlz1]

My tablet recently updated but during the update process its battery died because i didn't realize that the outlet wasn't turned on that it was plugged into. when i was able to charge it back up there were errors because it kept sending me to the HP PC Hardware Diagnostics UEFI menu. I've run all the tests and all the tests pass but when i try to continue booting it shows me a black screen with a little bit of writing at the top left corner which says: 

BootDevice Not Found

Please install an operating system on your hard disk.

Hard Disk - (3F0)

F2 System Diagnostics

i've tried entering the bios setup to try to update the bios hoping that would fix the issue but i can't even change the boot device to anything else without entering the BIOS administrator password which i've never put a password on it so i don't know that. oh and i've read all over online that when you enter the password wrong three times it will say the system is locked and give an error number but mine doesn't even give me anything it just says its locked and to press power button once to turn off and press it again to turn on. can anyone please help me? this is driving me up the wall...

Entering the wrong code three times usually forces the display of a Disable code -- but we're not permitted to provide Disable Code bypasses anymore.

Passwords can NOT be recovered; instead, they have to be reset.

If your PC reset your password on you, we can not help in that because we have no access to either the original or the new password.

We are not permitted to assist in resetting passwords due to HP Policy.
--------------------
To reset Admin passwords, you have to contact your regional HP Customer Support location directly for assistance.

--------------------
BIOS and power-on passwords are contained in the firmware that is present inside the BIOS chips -- which are soldered to the motherboard and thus, are not replaceable. So, you can't just buy a replacement chip and swap them. Also, neither your nor HP can reset the BIOS password on the current motherboard. Thus, replacement of the motherboard is required with one that has a BIOS chip that does not have a password in the firmware. This is very expensive to do and can often cost more than simply replacing the PC

If you are not prepared to spend the money to get HP to replace the motherboard, you would have to take the PC to a local repair facility to see if they can do anything for you -- but we can not assist in that in any way.
