You have turned off secure boot, right? Which OS is working right now? Can you run grub manually from the UEFI prompt? Can you get to the UEFI prompt? Are you trying to install Windows second after a successful Linux install? Randall Mason clashthebunny@gmail.com On Fri, Mar 25, 2016 at 9:10 AM, Richard Klein <rich@richardklein.org> wrote:
Have you considered picking one OS, then running the other in a virtual machine?

You really really really need to give more details here, otherwise no one will be able to help you.
For example, can you install and boot linux Mint by itself without any problems on this board?
I assume you can do the same with Windows 10 as well, right?
So did you install Win10 first, then shrink it and install the new bootloader to let you choose between Win10 and Mint? But it broke both I suspect.

Check with your vendor for an updated BIOS. Some have bugs where they have locked things down too much, and don't provide a good way around it as I recall. Haven't had to make this leap myself yet...

Can't tell really, since you don't give any details. I'd say it's possible, but you might need to tweak your UEFI BIOS to allow non-signed keys to boot.
Have you looked at ...uum.... Mathew Wilcox? He's the Linux EUFI maintainer and has a blog out there on stuff like this. Oh wait, it's Mathew Garret. Take a look at his blog:
It might have some pointers.
But please, more details would help us help you.
