What does not recognize the table partition ? You don't need a table
partition: just tell grub that the root is (hd0).

If it really wants a table partition, then you can fdisk /dev/hda10 and
create a partition starting at 1 and ending at the number of cylinders
of partition hda10. Beware of correctly setting the geometry the same as
hda in terms of heads and sectors.

This is dangerous: in linux, there is no coherency between hda and
hda10, so mounting hda10 in linux then using it in qemu via hda will
result to a corrupted system.
