Well most of us we are having the same problem no idea why...
I've touched everything in bios and keeps going wrong, I've touched ASCI SATA. I've put as first boot in bios my HDD and then in loading screen when I turn on the computer on I press F12 to chose from where I want to boot... I chose USB bla bla...
Everything works from my USB, windows, hiren's... bla bla and even the linux isos, but then same problem.
