I have an Asus P8Z77-V Pro. I have five 2TB disks connected to the Z77 SATA ports. I have them configured in a RAID5 array. This yields 8 TB usable.
I want to install Windows 7 to this disk. I want to have a single C drive with ~8TB usable.
Any time I boot in UEFI, I can't see the RAID disk. Is that normal/expected?
If I boot BIOS and I load the Intel storage drivers during install, the Windows 7 setup will see the RAID array and install to it, but it labels the array with MBR (not GPT) and therefore won't allow a C drive over 2TB.
How do I get Windows 7 to install using GPT to the full 8TB partition?
It not clear, did you load the Intel RST driver during install when booted in UEFI? You still need to do this, even in UEFI mode.
If even after loading drivers you don't see the RAID array in disk list, check that in MB Setup menu array is present in boot order list
