Do you have any other disks in this system apart from hda and hdb? I'd
say /dev/hda1 is almost certainly the correct /boot partition, but I
don't know where the duplicate is.
You should be able to fix things as follows:
1. edit /etc/fstab and change "LABEL=/boot" to "/dev/hda1"
2. fix up the contents of /boot as follows:
# mv /boot /boot.current
# mkdir /boot
# mount /boot
# mv /boot.current/* /boot
# rmdir /boot.current
If you get an error message at any point, stop and post details of what
happened.
Paul.
