Dell m4600 - Changing the detection order of the SSD and SATA disks

I have a dell M4600 laptop, with a 750gb sata disk as well as a 128gb SSD.

I want to use the 128GB sata disk as the 1st disk in the system (so windows will go on it without bleeting), and the 750gb disk for redhat.

The factory configuration seems to be the 750gb disk as the 1st detected disk, and the 128gb as the second.

I've taken it apart, and been through all of the Dell manuals I can find in the hope of being able to just switch slots (it seemed to make sense to me anyway).

None of the manuals seem to mention the SSD, and I certainly can't seem to locate it.

Is what i'm trying to do even possible ?

Any help would be appreciated.

Cheers
