Allowing boot of Ubuntu on a Acer Aspire v5-531 with UEFI

Question

I was trying to install Ubuntu 14 (64-bit) on a Aspire V5-531, preinstalled Win 8. In the bios I can flag:

boot mode UEFI, secure boot DISABLE

in this case the neither installation USB card nor cd rom start

boot mode in Legacy Mode

I can install Ubuntu 14, but grub doesn't work (yes, I used boot repair, but it doesen't work properly).

I resolved it this way:

let boot mode UEFI enabled, secure boot enabled
in BIOS added the USB boot file of the distribution I want to install as trusted for executing:

My BIOS is Phoenix SecureCore Tiano Setup

Under Boot I flag Boot Mode UEFI
Secure Boot ENABLE
Under SECURITY select: Select an UEFI file as trusted for executing
in Available File System I select fs0:$nameofmyusbkey
Select [EFI]
Select [BOOT]
Select BOOTx64.EFI
Give it the name whateveryouwant then, using tab, select YES.
so I go to the Boot option, then put whateveryouwant as first in the Boot priority order
then I was able to start Ubuntu installation in UEFI mode! :)

WARNING!

Before I did all this, I freed the space for my partitions under Windows 8. I read so many guide about UEFI and UEFI install (I give advice to do it!), and tried in several ways. That was the only way I was able to do what I wanted.

perfect thanks.......I had a different model but once reading Select an UEFI file as trusted for executing everything fell into line.....Also if its blacked out simply add a supervisor password and continue :) – damien May 08 '17 at 14:45
