I'm a little bit confused at to how you're even able to mount /dev/hda3 
after you've used it as a virtual disk for Windows, which should have 
installed a partition table on it, not a raw, mountable partition.  When 
I've done this sort of thing, I've needed to use kpartx.
At any rate, you will need a boot block, so copy the first 512 bytes 
from /dev/hda3 to /dev/hda6.  (dd bs=512 count=1 if=/dev/hda3 of=/dev/hda6)
If your hda3 and hda6 are exactly the same size (or hda6 is slightly 
bigger) you could just dd the entire partition.
