Hello all,
I've run into a curious problem. I'm booting Windows 8, openSUSE 13.1, and Ubuntu 13.10 all with SECURE BOOT enabled and get the following error from grub2 when trying to boot Ubuntu
error: /boot/vmlinuz-3.11.0-15-generic.efi.signed has invalid signature
error: you need to load the kernel first
Windows has its own drive, the linux distros are installed on the other. the EFI BOOT partition is on sda4 with windows, created when windows was installed first.
YAST install of grub does the following: openSUSE boots fine, Windows boots fine, Ubuntu errors out. If I disable secure boot, everything works fine.
I tried Ubuntu's grub2 installation, and it correctly booted all three OS's with secure boot enabled and disabled.
I realize the short answer is to just use Ubuntu's grub installation, but openSUSE is the distro I prefer, and I really want to know why this is happening.
Any help is greatly appreciated.
