Installing Win7 64-bit on RAID 10 Array

Apart from pulling the little hair I have left out, I'm having some real issues when trying to install Win7 64-bit on my RAID 10 array.

My motherboard is an ASUS P8Z77-V Deluxe and I have 4 x 2TB Seagate Barracuda drives. On booting up, I have gone into the Intel Rapid Storage BIOS utility and have created a single RAID10 array using the 4 disks.

I then booted up from the Windows 7 install DVD (UEFI compliant) and performed a custom install. When it asks where I would like to install Win7 it shows me just a single 3.8TB disk. At this point I then selected "Load Driver" and browsed to a USB stick where I have the Intel RAID drivers and loaded those up.

I then press (Shift)+F10 and type Diskpart at the command prompt. Select Disk0 and then type Clean before typing Convert GPT.

I then selected "New" and told the system to use the full available amount of space to which I then end up with 3 partitions, one being 100Mb, the other 2TB and a 3rd for 1.7TB.

If I continue to install Windows 7 on the 2TB primary partition, then on completion in the Windows Disk Manager, it reports that I have a C: drive of 2TB and an unallocated partition of 1.7TB (approx.) that is then totally unusable.

I'm obviously failing to do something right here, but can't figure out what it is... Having spent 2 and half days solid on this without any success, any solutions would be greatly appreciated.

Many thanks.

UPDATE:

I'm not sure why I recieved an email saying that my thread had been removed and asked that I complied with Rules of Conduct and guidelines for posting. Well I thought I had seeing there was nothing in the post that is offensive or inaccurate? Talk about confusing.....

How to fix, I don't know. The 100MB partition is your boot loader. The 2TB partition is the largest partition Windows can access on basic drive. Windows can address larger drives but they need to be created as GPT (Graphic Partition Table) drives. The only way I know to do this is from within a Windows installation. Whether Windows can be installed on a GPT drive, I also don't know.
