Mark partition bootable [Bootcamp]

Hello all,

I have just upgraded my hard drive in my Mac Book Pro. After upgrading, I reinstalled SN (clean install).

On my previous drive was a bootcamp partition, so I mounted it using an external SATA enclosure, and made a image of it using disk utility.

On my new drive I created a new partition matching the exact size of my previous one, and loaded the image onto it (again using disk utility).

This partition boots fine within Parallels and works exactly as before, however I cannot boot into Windows XP exclusively as when I hold the option key down at startup the partition is not listed. I am assuming this is because the partition is not marked as bootable.

How can I mark it, so I can boot into windows?

Kind Regards

Here is my df -h output:
