I've downloaded the latest .iso of Neon and proceed to installed. First, I do the same as with Arch:

Create a GPT table
Create EFI partition (sda1)
Create Root EXT4 partition (sda2)
Create Swap partition (sda3)
Create Home EXT4 partition (sda4)

Next, I choose /dev/sda1 to install the boot loader and install. A message is shown telling me something about UEFI (I did'nt remember). After install the system and reboot there is no boot loader installed and I can't enter to the system in any way. If I choose Legacy boot into the BIOS, after reboot shows me:

No device bootable found. Insert a media and press a key

I boot from the Live USB again and go to the /boot/EFI dir, which is empty. In Arch I just need to create a *.conf file into /boot/loader/entries dir, write the root partition UUID and the system boots fine.

How can I install Neon with UEFI boot loader?

Don't put the boot loader on sda1, just keep the default sda, and if you haven't, make sure that you specify in the installer's partitioning section that sda1 is the EFI partition - highlight it and click "change"

But here in / dev / sda1 worked
