Can't get to desktop after successful install on desktop PC

Hi everybody! I was just trying to install Sierra on my desktop computer but I got into a strange problem. I was able to install it, booting from my USB with Clover bootloader but after I rebooted I haven't been able so far to get to Mac's desktop. I don't know why, I booted in verbose mode and I don't see anything strange that is preventing my system to complete booting.
My specs are the following:
Motherboard: ASRock H61M-VS
Processor: Intel Celeron CPU G530
Graphics: I don't know...
