Hello,
I have an issue with my MSI MAG B550 TOMAHAWK MAX WIFI motherboard. I’m using the latest stable version of UEFI, and the problem is that with Secure Boot enabled, whenever I try to install a Linux distribution, the GRUB menu loads, but when I select an option to boot the system, the screen immediately returns to GRUB instead of proceeding further. Distributions like Ubuntu and Fedora have Secure Boot enabled by default, but they don’t suit my needs. If I disable Secure Boot temporarily to install something like CachyOS (my favorite distribution), it installs fine. However, once I re-enable Secure Boot, CachyOS stops working. I need to set up a dual boot with Windows 11 Pro, and I cannot leave Secure Boot or TPM disabled. Is there any workaround for this motherboard to allow unsigned ISO images to boot properly with Secure Boot enabled? It’s not easy to enable setup mode, and even if you do, all the keys from Windows are removed.
