GRUB Black Screen

Question

I "burned" the last Lubuntu ISO in a USB key and I can get to GRUB but if I select an option the screen goes black for ever

My PC is fully UEFI (I guess) and the nomodeset changes nothing

grub.cfg is like that

set gfxpayload=keep
linux /casper/vmlinuz  file=/cdrom/preseed/lubuntu.seed boot=casper quiet splash ---
initrd /casper/initrd

The USB key is on (hd0,msdos1). I tried without /cdrom and with (hd0,msdos1) and same

Some environment variable

cmdpath=(hd0,msdos1)/EFI/BOOT
root=hd0,msdos1
prefix=(hd0,msdos1)/boot/grub

If I don't use linux initramfs ask me to load the kernel first and if I don't use initrd I get a Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

I don't know how do I get further so I will just write what I did

I inserted an echo before set, an echo and sleep 3 after the set, same after linux, same after initrd and during the boot I typed gribberish on keyboard after all the echo and the lubuntu boot screen appeared but he disappeared after 2 second to let place to a kernel log

And from here I can CTRL + ALT + Fi to get to ttyi and log with the default Lubuntu account

I don't really understand what happen, but I'm further than before. But I can't reproduce it

It works too if I just rewrite linux and initrd a second time bottom and I mash Ctrl + Alt + Fi

In a nutshell it works rarely if I disturb the normal execution of linux+initrd in any ways possible

Than I can get to ttyi and launch X and work

But in normal times my problem still here

I found that the second method is reproducible

Considering that the last method is reproducible (but crappy though) and that nobody here have a better solution, I will consider that adding

linux
initrd

In the line after the normal menuentry of GRUB2 and mash Ctrl + Alt + Fi while black screen then login with default liveCD account then startx as the solution of my problem

After many test I seen that depending on the distribution the problem will occur most of the time or rarely. With Lubuntu here it's almost every times, but with Ubuntu it's like 30% of the time only, and it's completely random

In final all that I do is rebooting until it boots. Maybe a ticket to open about vmlinuz or whatever. I think it's related to a type of BIOS/GPU, who knows
