Could not to load from liveUSB: can't allocate kernel - Why is that?

[Alexander Verbitsky]

Hi all!

I have installed Fedora 20 on my laptop and everything worked. But now
i can not to load - after selection item in the grub menu appear error
"can't allocate kernel".

Also problem if to try to boot from Fedora-Live-KDE-x86_64-22-3.iso
after selection "Test this media & Install ..." or "Install Fedora.."

In the same time on another laptop of my colleague (that same as my)
everything is ok.

Tried with Enable/Disable Secure Boot in BIOS.

Can someone tell where to look and what's the problem?

Thanks!
