I'm trying to create a RAID 10 on a rebuilt but I am unable to so. During the Windows 7 clean installation I run into a brick wall. I get the message "Windows cannot be installed to this disk. The computers Hardware may not support booting to this disk. Ensure the disks controller is enabled in the computers BIOS menu." I have an Asus x.99 pro sub 3.1 mono with the latest BIOS ver 3101. I have 2x 1 TB seagate hard drive and 2x Samsung 850 EV0 500GB SSD. So this is what I did step by step. I reboot and go into the UEFI select EZ tuning wizard tab then RAID . I then select easy backup then RAID 10 then save and reboot. Back in the UEFI under advance I select RAID in the Sata controller 1 mode selection then under the boot tab dvd is selected there's nothing else to select then I do a restart to install Windows 7. When I get to "where do you want to install Windows?" There is another message towards the bottom no drives were found click load driver to provide a mass storage driver for installation. I click on load driver and browse the Asus x.99 CD for the 64bit raid driver. I select the folder IRST/driver/disk/win 7/64 bit driver or iaStorAC.inf is selected and shows to be compatible with my computer. Then next and at this point I am asked where to install Windows? There's only one Disk 0 unallocated space (931.5GB to select. Towards the bottom I have an exclamation mark "Windows cannot be installed blah blah blah next is grayed out. What am I doing wrong I've been at this for days and looked around but haven't been able to figure it out. I'm in a hurry trying to meet the free Windows upgrade deadline by Thursday so any help would
