Hi, I'm trying to build a new computer and I'm running into an issue where I'm not able to enable RAID 0 with two Samsung 750 SSD as boot drive.
I'm using the Asrock Extreme7+ motherboard and a 6700K CPU with 16gb RAM (2 x 8).
When I start the windows installation (Win 10 64bit), it does recognize the Raid 0 drive with full capacity (around 500gb, the two 750 are 250gb each).
But it says I can not install Windows on that drive.

I also tried to download the IRST drivers into a USB and used that, but no luck.

I'm not sure if it makes a difference, but I had installed windows in one of this drives, and I didn't format it before I created the Raid array, I'm assuming it would clear it up anyway.

Thanks, any help would be greatly appreciated.

I found the answer to my problem on this thread:

I basically disabled CSM, then during the installation, on the step you need to select the partition you want to install, I performed the following steps:

Hit Shift + F10 then, run the following commands:
diskpart
list disk
select disk x (x beeing the drive you are installing to)
clean
convert gpt
exit
exit

That's it.
Once I refresh, I was able to select it for installing.
