I have a MSI Z390M Motherboard and I was looking at some stuff while trying to get 'Secure Boot' ready for Windows 11. I've been using legacy mode instead of UEFI this whole time but when I try to go to UEFI mode, it just boots back to the BIOS screen. How do I get it to boot my Samsung 970 EVO like it does in legacy mode? Here is what I see in UEFI mode and when I click on the priorities button below it.

best way to do: clean install windows on uefi only mode (disable any csm and legacy option, save and exit, go to secure boot and enable it, then install the keys, accept/save and boot to bios again to make sure everything is uefi only and the secure boot is enabled on USER mode, and keys is installed (option would only be uninstall/remove keys).

Checks if your drive is MBR format

Follow the link to convert MBR to GPT, you will need to use /allowFullOS to work.

You can specific the disk number if its not 0. Eg, mbr2gpt /validate /disk:0 /allowFullOS

Once completed, restart and boot immediately into bios page and change boot mode to UEFI and viola.
