[opensuse] leap install messed up mint

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? Cheers, Dave -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
