Take a look here:
Hard Drive Size Capacities Calculator
500 = 465.66.
This is what I used: MB to MiB and GB to GiB conversions « Mythical Noppatech
Same thing? Maybe I got GB and GiB mixed round though?
So partitions of 465.6 GB (or GiB not sure) for Windows 7 and 232.8 GB (or GiB not sure) for the pre-installed Windows 8

Partition 3 - Primary - Where Windows is to be installed to.
It is imperative that these 3 partitions remain in the exact order as they are
