[SOLVED] EFI USB Device has been blocked by the current security policy

@Second_Coming I don’t see anything relevant in the Boot section.

I tried disabling Quick Boot, setting a Timeout, Disabling/Enabling “Automatic Failover”, and setting “New Boot Device Priority” to other values, and rebooting still gives the same error.

In case the instructions use a different BIOS version, I’m using InsydeH2O version IFR30.03.03.
