*Don't* boot the GUI! Boot into text mode. Nautilus, etc. is not
started and won't be restarted. Sometimes the GUI is not really easier,
it can in fact be much harder.
You should be able to login as root and use the CLI to do what you need
to do.
Note: in the case of mkinitrd, you will need to rebuild your initrd if
you expect to actually boot the machine after renaming the volume group
and logical volumes. You'll need to *manually* mount the root and /boot
(at least) someplace (eg under /sysroot), then chroot there. Don't
forget to fix /etc/fstab and /boot/grub/grub.conf (root=...).
