Comment # 20 on bug 1183884 from Projeto Linux Kamarada

(In reply to Michael Chang from comment #15)

I remembered that there is a specific setting on my BIOS. I needed to enable
Secure Boot, then an option became available: "Select an UEFI file as trusted
for executing". I navigated through a kind of file manager and selected
EFI/opensuse/grubx64.efi as trusted. I did this and disabled Secure Boot again.
Then I was able to boot from "opensuseleap".

According to efibootmgr -v, I booted from "opensuseleap".

So, this seems to have worked:
