Zorin won't to start

Before the problem occured, zorin didn't want to restart and I resatred it manually by pressing restart button on computer case. After that I see the text which I've provied to you.

How to solve problem?
I didn't created swap and home partition during OS installation and i used ext2 file system because I installed Zorin on SSD.
