I am trying to create an entry in nvram to boot an os of my choice. I have the xxxxxxxxx.efi file for it ready and placed in the second partition that is 32 bit FAT formatted for EFI and also contains my Windows and other OS loaders.

I have understood the syntax for referring to a HDD and its partitions as sda1, sda2 etc. so that I can type /dev/sda2 for eg. But with nvme I am not sure.

I have a single such nvme sdd in the only M2 slot on motherboard. How to address the second partition in it for efibootmgr command?

In both Fedora and PCLinuxOS Debian edition which I have installed recently it seems I need to add the only user to sudoers list to perform certain actions.

How to do this?

Fedora KDE version does not seem to have all packages available through Discover.

How can I see all software from Fedora repos?
