I am trying to create my first unattended installation file for Windows 8.1 Pro from MEDIA. I am trying to create 4 partitions with the following aspects:

Part 1 = 350 MB for the needed microsoft files.

Part 2 = 60 GB for Win 8

Part 3 = 40 GB for data

Part 4 = What ever disk space is left for data.

Here is my file so far....
