Dual boot problem - XP ptn not seen.

Hi, I have an old PC I keep for testing things, development, etc. It had copies of XP on it but I wanted to install Windows 7 (and keep XP). From a boot manager point of view it seemed better to install XP first, which I did. I set up partitions (I wanted W7 first then XP) but the XP installer seemed to want to go into the first partition. So, I installed XP in the fist partition (40GB). I then copied that partition (using a utility - Acronis Disk Dir from a Hiren CD)) to another place further down the disk, then installed Windows 7 at the start of the disk. So far so good.

However, I can't seem to get the Windows 7 boot manager to see the XP partition and add it to the boot-up list (using Bootrec from the repair disk). If I boot W7 it can see the XP partition and as far as I can see things look ok, file-wise.

Any ideas how I can make the XP partition bootable and add it inot the W7 boot manager list?

Thanks for any advice, John
