thanks uncle that got it working
boot live disk, start root terminal, then
[root@localhost root]# fdisk -l <Enter> <-- That's a lower case L not a number 1
to see which drive you want to check, /dev/sd0, /dev/sda/ etc
unmount drive(s)
[root@localhost root]# umount -a
then fsck the appropriate drive ,i.e.
root@localhost root]# fsck -f /dev/sda1 <Enter>
that got my system started anyway
