Today I created a new one bootable USB, and I installed Fedora. After I reboot the system without USB and picked Fedora in Grub2 menu. Still got same errors, but then the system started, I saw a Fedora's ''ballon" then, the full 'F' after 30-sec freezing I got a grey screen with a cursor in the right bottom corner of the screen and it was the end of Fedora booting. The Live version (from USB until installation) was working correctly but installed Fedora on my hard drive won't boot.

Currently, I Tried to install Ubuntu 18.04 LST and after installation, I Got the same problem - I Rebooted the system, choose in Grub2.0 menu Ubuntu and Ubuntu started to load, after loading I got an only clear screen with the cursor in right bottom corner, and that is all. Unix OSs won't boot. Why? 

thank you for your reply, I found the answer to my question. So it is:

Select the current (newest) fedora kernel boot entry in the GRUB boot menu and press the E key.
Add nouveau.modeset=0 rd.driver.blacklist=nouveau at the end of the line beginning with Linux.

After that, I already got a login screen and logged to the system. After that, I installed Nvidia drivers (using bumblebee as I have 2 VGA Intel and Nvidia)

So after that actions, Fedora works fine. Thank you community xD

In Ubuntu the same line but you have to only write "nomodeset" and remove "splash quiet"
