Restoring Windows 8 to factory state, without deleting secondary

Hi ya'll.

I have a 3-months old Dell laptop, which I need to do a factory reset for, using the recovery partition.
Since I don't have an external hdd available, in order to backup everything I needed (roughly 95 GB), I shrunk my C drive by 100 gig and created a secondary partition, and just moved my files there.

Now, if I remember correctly, unlike windows disc-installation, it won't let me choose which drive to format and install the new OS on, it'll just delete everything and restore it to the state it was in when I first got it.


Since both drives are on the same HDD, will it actually be deleted? (the secondary drive).
If yes, what can I do to "tell it" not to touch that drive?


System:

Inspiron 15 3537
I5-4200U
6GB DDR3
1TB 5400RPM
AMD RADEON(TM) HD 8670M 2GB DDR3


Thanks!
