How to fix 0x1A Security Violation on Linux Mint

I recently jumped over to Linux Mint 21.1 and upon rebooting to get into the OS for the first time I was greeted with an error that it couldn’t find the boot partition.

I found this strange, so I put the flash drive back in, and I was going to boot into it when I started getting:

ERROR

Verification failed: (0x1A) Security Violation

I started reading around, and it seems like the error might be related to signed files on the flash drive not being up-to-date with what UEFI has on record?

Either way, after trying a few solutions, the only one that worked for me was to disable Secure Boot within my BIOS settings. So there it is, if you’re having the “Verification failed: (0x1A) Security Violation” error, please try and disable Secure Boot. It also fixed the issue I was having with Mint not wanting to boot…
