High Sierra stopped working on mac mini 2014 after using it for a while

Hi, I've installed High Sierra since a few month and used it. It was sometime slow but it worked. I still have over 250 GB free space available.

This morning, my mac won't boot. The loading bar stop moving near the end and stay stuck. My computer automatically start at 7 am and when i got back from work around 5 pm, it was still stuck.

I unplugged everything except the keyboard and ethernet cable;
unplugged the power cord, waited a few minutes;
resetted the pram;
restarted in recovery mode and did First Aid (for what it worth) and according to that everything is fine;
tried re-installing High Sierra and still, it get stuck on restart;
safe mode won't start either.

My backup is not up to date but most of my important stuff is on a cloud drive. Is there something else i can do besides First Aid?

Thanks

Mac mini (Late 2014), macOS High Sierra (10.13.2), no fusion drive

Thanks Eric, most of those solutions are great when you can startup the Mac somehow. The other ones talking about the “grey screen” have already been tried.

I’m beginning to thing that it have something to do with some of the latest Apple security updates... should’ve stayed with Sierra...

None of the above guides work as they assume my mac starts. I clicked the 10.13.2 update and ever since, the update progress stalls at 100% after reboot. there is no login screen. i can option click when powering on but that doesnt do much. safe mode doesnt work. this has to be another screwup update from apple considering i did a clean install with high sierra.
