FC7 Grub problem

[antonio montagnani]

My grub stops at start-up with grub> saying that a minimum hash etc, etc...
It seems that something is wrong in my grub.conf:

my grub.conf in /etc is:

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
#          initrd /initrd-version.img
#boot=/dev/sda
timeout 5
default 0
	root (hd0,0)
	kernel /vmlinuz-2.6.21-1.3194.fc7 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
	initrd /initrd-2.6.21-1.3194.fc7.img

What is wrong??
