I was interested in trying out openSUSe and tried to install it on my third drive:

on my first and second attempt the install failed with an error that the creation of the efi Boot partition failed
something along the lines of:

execution of command /usr/sbin/shim-install failed no space left on device
(i tried both manual and automatic partitioning)

i then tried to install fedora on that disk, just to see if something is wrong with the disk (or my skill) and it worked without a hinch.

after that i tried it again with tumbleweed and it seemed to install just fine.
but when i tried to boot it didn’t work,
it just showed a black screen with a blinking - for about a minute before rebooting.

i gave up after that.

is there something that i might have missed during my install,
i thought that openSUSE has a great reputation.

system is a ryzen 7 with an rtx 2060,
on an ASRock mainboard with secure boot deactivated.
disk is my old 250gb samsung 840 evo
