recovery/setup partition without wiping secondary drive?

[Tanqueray]

Hi, I've been googling for a long time and have read alot of info, but have yet to find anyone trying to do what I'm trying

I'd like to make an unattend that creates 2 partitions on 1 disk

the first partition is the OS / system disk

the secondary partition is the "recovery/patches/software installs" disk

I can understand the initial creation of the partitions and that's fine

but what i've done is created a winre.wim image that instead of running the recovery environment, runs the setup.exe as we'll be copying the cd contents to this secondary partition. when we tried to run the recovery environment there was too many issues trying to find drivers for some oddball reason, so we figured may as well run the setup again as we know that has no problems with drivers. We use many computer types, so we are not injecting and constantly updating a driver database into the image, trying to minimize the upkeep workload.

now my issue is this, is there a way, using the same wim file/unattend, to be able to install vista on a machine, which then copies its own installation files to the newly created secondary partition, to then be able to press F8 (winre.wim) when the OS is acting up and be able to wipe that first partition without wiping that secondary drive that has all the latest and greatest patches/software

This way, if a user is out in the boonies somewhere and his pc decides it's had enough, a user can hit F8 to reinstall his machine from the secondary drive, and already have all his patches/software ready for reinstallation.

Is there a way to set a condition that if a 2nd partition exists,only format the first partition and not the second one?
