Trouble installing windows 7 on RAID in UEFI

As the title says, I'm trying to install Windows on a RAID array in uefi on my Maximus V Formula. When using legacy ROM I can install just fine but I go into CSM and change settings to UEFI only, I can build the array in the UEFI Raid driver (IRST tab in "BIOS") but the array does not show up in the boot menu and when I try to install windows (boot from UEFI DVD drive), The drive does not show up in the Windows install. The next thing I tried was to enable UEFI and legacy oprom in CSM, boot from UEFI DVD drive and install to the RAID array (probably detected by legacy oprom) and it will install. After first reboot, Windows Boot manager will show up as an option in the BIOS boot menu so I set that as first boot device and reboot. I will get to the starting windows screen and then BSOD (too quick to get codes) The last thing I tried was Changing to legacy mode and installing windows to a different drive. once installed, I initialized the Raid array as GPT and rebooted, changed csm back to UEFI only but they RAID array still doesn't show in the boot device list so I repeated the earlier process hoping that It might work because I had initialized as GPT but it still BSODs on starting windows screen. Any help or suggestions would be greatly appreciated

 

Windows 10 (64): Mirroring the boot drive

My boot drive (C is 111.79GB SSD drive. I have another SSD, but is 256GB.

I would like to mirror the boot drive to the second SSD and then make use of the remainder as a work area. Is this possible? Are there any gotcha’s or things that I should watch out for?

Can someone also please detail the steps to accomplish this? When this is done, can I boot off either partition? I believe the second location be added to the list of items to try and boot from in the BIOS. Please confirm this.

I tried mirroring but stopped when I received the following warning message………..





Don’t want to destroy something or have to re-install the OS and the applications.

My disks look like the below and would like to use disk 5 to mirror disk 2 and the remainder as a work area:

I think you were on track with your first try. Windows installer probably needs the RAID driver in order to detect it on install.
