If you can’t start Windows, you may be able to perform a system restore in the Windows Recovery Environment. Here’s how:

Step 1: Start your Surface using a USB recovery drive. Insert a bootable USB drive into the USB port on your Surface, and then press and hold the volume-down button while you press and release the power button. When the Surface logo appears, release the volume-down button.

Let us know if it worked for you.

hi. thank you for the reply. ive restored windows several times.

the operating system has no effect on the bios. so reseting or reinstalling windows does not roll back the firmware.

either way, i need to update the firmware

The only thing close to your problem I could find is this, maybe it helps:

Reset from USB recovery media

Step 1: Make sure that Surface is shut down and plugged in.
Step 2: Insert the USB recovery drive into the USB port on Surface.
Step 3: Press and hold the Volume Down button while you press and release the Power button.
Step 4: When the Surface logo appears, release the Volume button.
Step 5: When prompted, select the language and keyboard layout you want.
Step 6: Tap or click Troubleshoot, then tap or click Reset your PC.
Step 7: If prompted for a recovery key, tap or click Skip this drive at the bottom of the screen.
Step 8: Tap or click the target operating system you wish to reset. This refers to the current operating system installed on Surface.
Step 9: Tap or click Yes, repartition the drives. On the next page, tap or click Next.
Step 10: Choose either Just remove my files or Fully clean the drive. The option to clean the drive is more secure, but takes much longer. For example, if you are recycling your Surface, you should choose to clean the drive. If you are keeping your Surface, you just need to remove your files.
Step 11: Tap or click Reset.
Surface will restart and the Surface logo displays while the reset process completes (this can take several minutes).

If this is still not what you need, maybe you'll have to contact Microsoft support and see if they can help. Good luck.
