Set up EFI with Ubuntu

Question

I just bought a new barebone (this one) and added a 250 Gig SSD + 8 GB RAM. (The point is that the hardware is entirely new).

I installed Ubuntu (and after that OpenElec just to compare and I am having exactly the same problem). When I have the Live-Stick plugged in, I can boot the live version from it as well as install from it, when I boot the PC and the stick is plugged in, I can see its boot selection.

Now after I have installed Ubuntu (or OpenElec) and I am trying to boot from the disk all I get is a black screen for 5 seconds and then my PC switches to the EFI config screen.

I can boot the live version and check my SSD, I can see there are 2 partitions and one is EXT4 and one is EFI, so the disk can be seen at there is a bootable partition.

However, it appears to me that my EFI Bios does not recognize the SSD. Because I have an option in my EFI that says "Write secure keys to disk" and when I try to do this, it says there is no file system for that.

I have used boot info to create a report: http://paste.ubuntu.com/p/nwD3p6GMF9/

Now I am all out of ideas why my PC does not seem to recognize or boot Ubuntu.

Edit: As to the duplicate question flag: This is a different question. The anwser might also bei reEFInd, but the problem is different. Also it turned out I needed to flash my BIOS, which did not work well with my SSD.

You have an EFI problem, so have you tried to see whether rEFInd finds and can boot your currently installed Ubuntu boot? — Fabby, Mar 18 '18 at 08:40

It turned out I needed to flash my BIOS, which did not work well with my SSD (it did not really detect it). This was a bug in ASUS' UN45 Model.
