1 What is Secure Boot?
Secure Boot is a new security feature that available only on PCs that has UEFI enabled to blocks the loading of uncertified bootloaders and drives. It helps to prevent your Surface from being loaded with unauthorized operating systems and malicious software applications. All Surface devices ship with Microsoft’s certificate stored in UEFI to verify boot loader integrity before launching it.

Secure Boot is configured by selecting a Secure Boot certificate keyset. There are three keysets to choose from on this PC.

Hi Mike,
If you can boot to Windows, you should boot to Surface UEFI via Windows Recovery Settings, as I detailed in the https://surfacetip.com/remove-red-bar-surface-boot-screen/.
There is also another approach that you use to boot to UEFI by using Recovery USB. When you can boot to USB, you can use the recovery mode to boot into UEFI and turn on the Secure boot to remove the red bar.
