I don't know why. What I did: cd /boot rm -fr * gummiboot install grub2-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=grub_uefi --recheck (and maybe run kerninst to actually put a kernel and its initrd there) The grub2-install-command was just taken from shell history. It might be *wrong* ... yes. At least it says it runs without errors. When I run: # grub2-install --target=x86_64-efi --bootloader-id=grub_3 --recheck Installing for x86_64-efi platform. grub2-install: error: cannot find EFI directory. > Can you create an entry for your kernel in 40_custom and test it? > > Take a look at grub.cfg.

That doesn't matter btw ... the reason to have grub2 in parallel is just the feature to boot iso-files (rescue media ...). All this additional grub2-fiddlery is basically learning how to make it work and getting the convenience of not having to insert a CD now and then. For daily work I am perfectly happy with gummiboot *just* booting my kernel(s) ... which works already! thanks, regards, Stefan (leaving now ... late here as mentioned)
