Custom Symantec System Recovery 2013 Disks

I'm using SSR 2013 SP2 trying to create a custom system recovery disk (64-bit) with an Intel C600+ AHCI driver for a new HP Z440 workstation.

The WinPE version is 6.3.9600 which is Windows 8.1 and i have added the driver using "Create Custom Recovery Disk".

I added The Intel C600+/C220+ AHCI driver version 4.1.0.1046. When I boot with the custom recovery disk I cant see any hard drives.

Does this have anything to do with the fact the workstation is UEFI and a GPT based disk for the operating system?
