Interrupt the boot process in the same way as you do when booting into
a previous kernel and then edit the grub boot line to add a run level
at the end - so '3' to boot multiuser without a gui or '1' to boot into
single user mode. The line you want to edit is the one that has 'rhgb
quiet' in it - you might want to remove those as well so that you can
see what's happening (although you will get ALOT of output).
