Installed Linux don't boot

Hello,

I'm in possession of a A320M Pro4 that I just buy, but it seems that I have some trouble with it. I installed Ubuntu Linux 17.10 (latest version) and though the BIOS show me the option in the boot options ...



... When I select it, nothing happen (the screen goes black for like half a second, then the choices pop back on screen). Ubuntu has been installed with UEFI, and if CSM is disabled, only the "SATA_X" option disapear, but same behavior. So the BIOS is able to boot the USB key, but not the actual installed system ?!?

I use the 3.40 version of the bios, and I can upgrade to 4.50 if needed (though I doubt it would change anything according to the sparse changelog). So if someone is aware of an option that I forget to enable/disable, that would make my day !

Thanks in advance :)

(also, if someone have an idea on how to get an error log or something, that would be nice)

Maybe (I posted a message there as well, and I did almost everything recommended on that page, maybe not everything recommended on http://www.rodsbooks.com/linux-uefi/, though), but generally, either people cannot boot their LiveUSB because of UEFI, or everything is OK, and the problem happen in the next steps (i.e. kernel panics, wrong drivers and other stuffs). My situation is that I'm stuck in the middle: only liveUSB boots (and everything run perfectly),  not installed the one, which does not make any sense (that should be almost the same!). I cannot even access GRUB, so it looks really like a BIOS problem (or an odd installation problem o_O).

if windows works than theres nothing wrong with bios, it just runs efi shell apps from your drive

try this:
boot from live disk or something to get to uefi mode

You can view the existing boot entries with "efibootmgr -v". This will reveal either a lack of an EFI entry, or perhaps a malformed EFI entry.

If you have an entry already, or if there is nothing there at all, rebuilding the GRUB should invoke efibootmgr to create an entry for you. This is the easiest course of action. You should do this within a chroot of your already installed system (another reason why we're using a live system). If you don't know how to set up a chroot environemnt, please reference this guide:
https://help.ubuntu.com/community/BasicChroot

After that is done, reinstall the GRUB package:

sudo apt-get install --reinstall grub-efi

Once that is complete, stick the GRUB on your disk again:

sudo grub-install /dev/sda

Re-create your GRUB config (this should invoke efibootmgr as well):

sudo update-grub

Check that you have EFI boot images in /boot/EFI for your linux install. You should have directories for both Windows and Linux side by side, with .efi files in each.

Finally, check that you have a proper boot entry in your EFI NVRAM using efibootmgr -v
