I'm trying  to dual boot W10 and TBW (snapshot 20160913).
The two os are on two separate physical disks.
If I tick "Enable secure boot", which I suppose is needed to boot a UEFI
system, with bootloader set to "GRUB2 for EFI" and Protective MBR flag to "Do
not change", the bootloader returns the following error:

Error
Execution of command
"[["/usr/sbin/shim-install","--config-file=/boot/grub2/grub.cfg","--no-nvram","--removable""]]"
failed.
Exit code: 1
Error output: Unrecognized option '--no-nvram'

shim version: 0.9-5.30

I've checked shim-install options out and no-nvram is not listed within them.

Reproducible: Always

Steps to Reproduce:
As described above.
Actual Results:  
Secure boot support is not enabled

Expected Results:  
Secure boot support enabled
