Systems Deployment

Ok so my situ is i work for large gaming company and in previous deployments\rollouts of xp we used to have the harddrive partitioned in 2.
1 - XP
2 - recovery partition (Automated, created with ping software)
We created this setup as the users need to be able to hit the recovery partition on boot to have a clean install of xp after finishing there game testing.

Now that Windows 7 has come along i need to have a setup on 1 harddrive as:
1 - xp
2 - Windows 7
3 - recovery

or

1 - xp
2 - recovery
3 - Windows 7
4 - recovery2

I have managed to do the sys prep & image of both os's and get the option of
1 - xp
2 - Windows 7
3 - recovery

on boot up. But i cannot seem to get the recovery partition to be automated or contain both os's with out screwing up the mbr.
I need to have a automated (no disc to be inserted) recovery partition as there are thousands of users and would take up too much time for the IT department.
Even if I could get it to recover from the network that would be good??
I have spent weeks trawling the net\forums but to no avail. [&o]
Can anyone advise please?
Thanks in advance.

system specs vary .
