Unhappy Kernel panic - not syncing: VFS: unable to mount root fs on uknown-block(253,0)

/dev/sda1 = /boot = bootable partition
/dev/sda2 = LVM Partition
/dev/lvfelix/root = /
/dev/lvfelix/var = /var
/dev/lvfelix/opt = /opt
/dev/lvfelix/home = /home
/dev/lvfelix/usr = /usr
/dev/lvfelix/swap = swap

Finally i start the installation, then when it finished that i had to boot the operating system, this message shows up(See the link below)

You'll need an initrd to start LVM up so that you can mount your boot partition.

In the meantime, use your installation DVD/CD to boot up. Don't attempt to mount your partitions, but accept the huge kernel, the default keyboard, and log in as root. Once you've done that, enter the following commands...
mkdir -p /var/lock/lvm
/sbin/vgchange -ay --ignorelockingfailure
/sbin/udevadm settle --timeout=10
mkdir /mnt/fix
mount /dev/lvfelix/root /mnt/fix
mount -R /proc /mnt/fix/proc
mount -R /sys /mnt/fix/sys
mount -R /dev /mnt/fix/dev
chroot /mnt/fix
mount -a
...and at this point, you should be able to run the /usr/share/mkinitrd/ script to create your initrd. Ensure that /etc/lilo.conf has the correct stanza in it and re-run lilo. Reboot.

You might want to point /boot/vmlinuz to the generic kernel, too, before you re-run lilo and reboot.
