Installed xubuntu. Pc doesn't load uefi

[joaco72]

I have a new pc. It has a mother Asus with uefi. First of all I installed Ubuntu and don't gave me any problems. Then I installed debian 9 and it had some problems to boot. After that I tried to install xubuntu. When the installation was complete the system told me to reboot. I did so but nothing happened. I turned it off. Then I turned it on and nothing happened. The computer just doesn't start. Not even uefi. Fan starts working but nothing else. Nothing on the screen.
Uefi settings were set to default before installing xubuntu.
Any hint?

Are you trying to keep Windows on the machine and have Ubuntu on there at the same time?

Did you disable UEFI or are you keeping that? Did you tuirn off "fast boot" in the BIOS?

How many systems are actually installed on the machine now? How many do you want installed?

May be best to see details, you can run from Ubuntu live installer or any working install, use ppa version not ISO:
