I’ve just freshly installed Endeavour OS with i3 on my laptop without any error but when i restarted my computer, grub showed up, then system booted and… Nothing. Black screen…
Edit: I discovered grub option to boot from usb by entering some special commands that I now forgot (xD sorry)
So now I’m reinstalling Endeavour in KDE that like it was week ago
Sounds like a graphic card problem.
If you CTRL ALT F2. do you get a prompt?
What option did you pick on the live ISO’s GRUB? NVIDIA or Free?
I don’t know…
But I was installing Endeavour week ago on that machine but with KDE and with same installation settings and everything went good, with no problems.
Well that is genuinely weird. I’ll leave you in the hands of more knowledgeable people then 
welcome at the forum, and sad to hear that your install does not boot to X…
Without any information about hardware in use and no hint an what you choose on install process, hard to help…

Thanks but I have already reinstalled Endeavour (now with KDE), so I can see something after Grub and everything works.
i see that but it is interesting to see your boot log and hardware specs to may see if they could be the reason why i3 does not install…
nothing appeared when I typed this command.
But if you want my hardware specs, this is an output of hwinfo --short:
