Can't boot from USB

[jdenman]

Surface Pro - attempted upgrade to win 10, had a cisco component on it so no internet, tried to revert to 8 and it bricked windows entirely. I am able to get into BIOS setup and disabled secure boot control and trusted platform module, but it doesn't pick up on my USB recovery drive, whether it was setup for Windows 8 or 10 (I've tried a dozen different combinations).

The error I always get, is:

Recovery
Your PC/Device needs to be repaired
An unexpected error has occurred.

Error code: 0xc0000034.

Any suggestions, or do I need to take this to the store and pay to have it reset?

Welcome to the forum

In order to boot to USB make sure it's formatted Fat32.

Yep, it is. I tried both formatting as Fat32 first, as well as letting recovery format it.

Press and hold the volume-down button, when the Surface logo appears, release the button.
