I issued the command:

grub-install /dev/sda

I get the following reply
Probing devices to guess BIOS drives. This may take a long time.
/dev/mapper/VolGroup00-LogVol00 does not have any corresponding BIOS drive

and this is my fstab file

/dev/VolGroup00/LogVol00       /        ext3      defaults      1   1

LABEL=/boot                           /boot   ext3      defaults      1   2

none                                          /dev/pts   devpts   gid=5, 
mode=620   0   0

none                                          /dev/shm   tmpfs   
defaults   0   0

none                                          /proc   proc   defaults   
0   0

none                                          /sys   sysfs   defaults   
0   0


Any idea, or shall I revert to ext3??? (Tnx to Simon for his help)
