kali 2.0 black screen just after boot

Hi!
I tried to use Kali 2.0 in live mode on my Lenovo Z500 Idea Pad with UEFI. I made my USB stick with Win32 Disk Imager. After that I plug my USB stick and boot it in boot menu. For three times I was able to run it in live mode with no problems, later just after boot I got black screen with a screen highlighted and I was unable to do anything. After few tries it launched again, but just once. I was remake my USB stick, but without effect.
I saw another trhreads about black screens, but in my case i don't see Kali's menu (where is live or install option).
Could someone can help me ?

The way I get passed it is after the grub menu when you get the black screen type Ctr Alt F1, then it will ask you for your root login type all that then when you are logged in type startx, depending on your computer it may take awhile.

After I boot Kali from USB and get black screen i type Ctrl+Alt+F1 and nothing happens ;( I tried the same in GRUB menu, but with the same result.
