Stuck at loading bar, after installing!

Hello everyone! Before everything, sorry if this question has been posted a thousand time, but I can’t find anything!

I’m installing Mojave on my thinkpad carbon x1 1st Gen, everything is good, I installed from usb, reboot and finished the installation from hd, now at the final reboot after everything is installed I’m stuck at the loading bar (the bar charges until is full, but then nothing happen). What can be the cause of the problem? At some point the mouse appear, but as soon as I click it disappear!
