> OK a blank screen isn't useful information and no one can help. So what you have to do, is do things that cause information to be revealed to find out what the problem is. The first and easiest way to do that is at the grub menu, use e to edit the boot entry, scroll to the end of the linux line, remove 'rhgb quiet' and add 'nomodeset', without quotes, and then F10 to boot with those changes. Now report what you see.
