[SOLVED] Unbootable RAID 0 in BIOS

[Humprey]

Hello,
Recently I decided to upgrade my old computer. I bought MSI Z490-PRO motherboard , intel core i5 10400F processor, 16GB RAM. I used my old graphic ASUS GTX 660, and two WD Black 500 GB harddrives, which I set as RAID0. Everything worked well. Later by accident I set wrong frequency, system didn't boot and I had to reset BIOS. Motherboard booted but RAID volume with Windows didn't. RAID volume was still as existing in BIOS, but i could not set it as bootable in boot order. I tried other two disks, update BIOS - it didn't help.

I replaced motherboard by Gigabyte Z590 Gaming X, but problem is same. I can create new RAID volume in BIOS, but I can't set it as bootable in boot order. Interesting is that hard drives are correctly identified in bios, and if I set disks as AHCI, everything is alright. I use CSM mode, due to old graphic card.

What is wrong ?
Thanks for any advice.

I would use WDC's Data Lifeguard Diagnostics to erase/write zeros to both drives. That's the best way to completely return the disks to as-new

Why the RAID 0?

In the context of all this hardware swapping, you're doing a fresh OS install, correct?

I tried erase disks with this program. It didn't help.

I can't install OS. During installation process, RAID 0 volume isn't accessible. Windows sees created volume, but doesn't allow to use it.

Error message is: "Windows cannot be installed on 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."
