Bootable USB : Bootable device failed Secure boot verification.
I am trying to boot into Arch Linux live with a secure boot enabled USB. I am getting this error: OS Loader signature found in Secure boot exclusion database (dbx). Bootable device failed Secure boot verification.
Is Windows 11 or the Dell BIOS updates blacklisting the Linux to boot?
It is an issue with the distribution you're trying to install having an entry in the exclusion (not allowed) database. The technical details are linked below.
Actually I wanted to uninstall Windows 11 and install Arch Linux. looks like I have to disable the secure boot but I won't install in legacy mode. Thanks for the info btw.
There is no Legacy mode in this system -- you must use a Linux distribution that supports UEFI boot (a separate issue from there being secure boot support).
