The boot sector has the boot blocks but also the partition table. You
don't want to copy the whole boot sector. A better solution is to boot
your system using the 7.2 CD linux rescue system. chroot to the
directory you want to mount as / and run lilo to create the booter.

The simple answer is don't copy the /mnt directory. Do something like:
cp -a /boot /bin /home /sbin .......         /mnt/hdc6

tar would work also here with cd to / then run:
tar cf - boot bin home .......  | (cd /mnt/hdc6; tar xf -)

also remember not to copy /proc
