Bootcamp partition not bootable?

Hello all.

I set up a macbook pro as I wanted. I used OSX one one partition, Win7 on the other, installed all the apps required on both partitions and all was working beautifully.

The problem is that I have an identical macbook pro that needs the same set up, so I ghosted the disk, and restored the ghost image to the second machine. The mac partition works great and was as expected. The Win7 partition however DOES show up in the disk util, DOES show up in the startup disk options but DOES NOT show up in the boot manager. In the disk util the partition isnt bootable, and I cant seem to get it to work!

I've tried the old '$sudo fdisk -e /dev/disk0' and flagging partition 3 and setting it to active, but thats about all I could think of.

If anybody out there has any more ideas please feel free to send them my way. I need to get that partition active and it just doesnt seem to move!

I'm a bit of a n00b to the whole MacOS terminal thing so go easy on me haha!
