sda2 contains Windows 7 but without a mount point

sda6 should have been the Home partition and sda5 should have been the Boot partition but the mount points seem to have been lost and now everything but Swap has gone into the root partition sda8 (the Home folder also seems to be within sda8).

How do I go about getting sda6 used as the Home partition and sda5 as Boot
