I can't help you there.. I boot into init 3, i've never used GUI on Fedora, 
console only.

When you boot..

Highlight the kernel you want to load

press 'e' for edit

select the line that starts with 'kernel' and hit 'e' to edit that line

Go to the end of the line and type single as a separate word (press the 
[Spacebar] and then type single). Press [Enter] to exit edit mode.

Back at the GRUB screen, type b to boot into single user mode.

I figured, no worries.
