Fedora 33 Silverblue and Mac Mini 2018

Hi, I need help.
I can’t install Fedora 33 on my Mac Mini 2018 external ssd. I get this error:

I was able to boot Fedora Silverblue from external ssd on this Mac Mini for two years now, but it was installed using my old notebook.

PS Sorry for my English.

I don’t know the answer, but your English is fine – no need to apologize!

I’ve just found a possible solution here, but it is quite old, and I don’t know if it still works. I will try it tomorrow.

After complete installation, don’t reboot.
Quit the installer with CTRL+ALT+F2 and :
chroot /mnt/sysimage
grub2-install --force /dev/sdxx
where sdxx is the location you want install bootloader, for me it’s sda2
grub2-mkconfig -o /boot/grub2/grub.cfg
after quit chroot with “exit” command and reboot.
