Hi,

I formatted my RAID0 ssd's to start a fresh installation of Windows 10. I booted Windows with a USB key, and after selecting custom installation I get an "error".

"Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer's BIOS menu."

When I select the desired partition (or any other) I get this error.

"We couldn't create a new partition or locate an existing one. For more information, see the Setup log files."

Here's the weird part. When I enter bios an go through my bootable devices, there is no longer any of my SSD's or HDD. However, in the Intel Rapid Storage Technology menu, my ssd's and hdd appear. I can recreate my RAID0... So my disk are being detected and can be used, but why are they not appearing as bootable options?

I have tried using diskpart to clean, set as primary, format, assign and activate my disk (RAID0), and also activate the desired partition, yet Windows installation still will not proceed. I have tried a few solutions that I found my searching, but still no go. I also tried using a DVD copy still with no success.

My system specs.
Gigabyte Z270X Gaming 7
Intel 6700K
32GB 3200MHz OC
1080GTX
Samsung 850 Pro 256GB x2
1TB HDD

I don't know why you would make a partition to install OS to. A UEFI install would make:
◦Drive 0 Partition 1: Recovery –type Recovery;
◦Drive 0 Partition 2: System- this is an EFI partition that contains the core OS files, which are required to boot the operating system;
◦Drive 0 Partition 3: MSR- it is a partition that reserves space on each hard drive for Windows internal use;
◦Drive 0 Partition 4: Primary- this is the partition where all users data and Windows will be stored;

You would start with a disk with no partitions. You can delete all existing partitions. Windows will make the partitions it needs.

I've been running RAID0 for a while, and I have never experienced any issues. Through several formats I never had issues. However, my question is not about using RAID0, it's about the fact that non of my disk drives (SSD's/HDD) are appearing as bootable devices. This is what I'm hoping someone can help me with.

You're trying to install windows to non raid disks that were formally part of a raid partition?

No, I'm keeping them in RAID0.

What I've figured out is that if I run SATA Mode on AHCI instead of intel premuin RST my drives now appear as bootable devices. I booted Windows installation and can now install on either SSD... So now a new problem arises. Why aren't my 2 ssd's appearing as a single drive? When I originally setup my RAID0, I had to boot Legacy Raid setup, though, I cannot figure out how to get the option as available again in the Post Screen where I press CTRL+I to enter the menu...
