Run InstallPolicy.cmd again
Restart the tablet
Once you see the Secureboot screen, select the "Accept and install" option using the volume buttons and press on the Windows button to continue.

Issue 4: Error 0xc0000428 or 0xc000000f after first Windows 10 Boot

It appears that this error is caused when the option called "Back up system files to a recovery drive" was selected. If you do not disable this option, it will show this error. The solution is to create a new USB drive without checking that option and to re-start the whole tutorial again.
You can try this fix, however many people were still not able to boot Windows 10.
If your Surface shows error 0xc0000428 or 0xc000000f and says "A digital signature could not be verified", follow the steps below:
Insert your USB drive in the tablet USB port.
Hold the Volume down button and press the power button once.
When the Surface logo and the spinning circles are displayed, release the volume down button.
Select "Troubleshooting", then select "Reset this PC"
Select "Remove Everything" and select the target operating system (if required)
Select "Just remove my files"
It should reset, and restart to Windows 10.
