UEFI Build Test

[m654321]

Anyone wanting to use a as is where is test build of Linux Lite 3.2 with UEFI support can get it here for a limited time - http://repo.linuxliteos.com/uefitests/3.2/

I downloaded this uefi version of LL3.2 and attempted the dual-boot with win10 on my UEFI computer (setup1 in sig). The install stopped at the stage of the grub2 package with the following message coming up on the screen:

"The 'grub-efi-amd64-signed' package failed to install into /target/. Without the GRUB bootloader, the installed system will not boot".

When I re boot it goes straight into win10, with no grubscreen, as expected from the message.
Any ideas? I did follow the Linux Mint tutorial (that Jerry posted for the LL/Win dual-boot) to the letter - I have repeated the process 3 times with the same result each time.  When installing, secure boot is disabled and CSM enabled.  Can't see what I'm doing wrong - any help/advice much appreciated...

Cheers
Mike
