Good morning everybody.

Today I have tried to install Fedora 20 on my Sony SVE1512Y1ESI notebook.
First of all I have loaded a .ISO image on my USB pen drive, using very useful UltraISO program. At this point I have restarted my PC and, after appropriate configurations, I have run the Fedora installation which, unfortunately, has hung after just a minute.
What do you suggest I should do?

I express my early thanks to all people who will know to give me an answer.
