I had Mint installed on a machine, which also has W10, and it was all working fine. I installed Leap and that is working fine. When I reboot I get taken to openSUSE's boot menu, which is fine, and it reboots either Leap or W10 fine, but if I select the line for Mint it says
error: vmlinuz.... has invalid signature. error: you need to load the kernel first.
The machine has UEFI and is in secure mode and Mint was booting just fine using its own (well, Ubuntu's) grub so presumably has a good signature, so I'm currently thinking of this as an openSUSE problem.
Anybody got any ideas?
Short version: I think you're best off using the firmware's built-in boot manager to choose Windows vs suse, vs Mint, rather than expecting the suse GRUB to boot Windows or Mint; or the Mint GRUB to boot Windows or suse.
That makes sense to me. Sadly, the firmware boot menu is only showing Windows and I have no idea how to edit it or persuade it to edit itself. The machine is an Acer XC-705 and I haven't had any luck searching for specific instructions; I can't see anything likely in the BIOS menus; and I'm not aware of a generic UEFI mechanism to edit the boot menu.
Long version: Basically the distros have a bunch of mutually incompatible forks of upstream GRUB. And they don't care about multiboot at all. That's why it's broken, and will likely remain broken or at least a bad experience for most users for the foreseeable future.
I'm inclined to agree with you about this too. :(
If you use 'tree -L 3 /boot/efi' you should see that there are multiple GRUBs on your system. There'll be a Windows directory and bootloader, and two GRUBs, one in a suse directory and the other in a Mint directory (something like that, I'm not sure what the exact names are).
I can see those in /boot/efi/EFI. And I can see all three as options in efibootmgr
But the built-in boot manager will let you pick those directly,
But I only see Windows in this boot menu!!!
The gotcha is every UEFI firmware OEM has different F key shortcuts to get to the built-in boot manager. And the UI differs somewhat as well.
It's DEL for BIOS, F12 for boot manager, but I don't see any options to change the boot manager display Thanks, Dave -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
