It sounds like you are facing some issues with disk configurations after a failed Windows upgrade attempt and subsequent reset of your RAID disks. To resolve the problem where Windows sees all three disks as system disks, you can follow these steps: 1. Disconnect Non-Essential Drives: - First, disconnect all drives except the one where you want to install Windows. This includes the RAID disks and any other non-essential drives like the two SATA disks and the USB drive. 2. Boot from Windows Installation Media: - Insert the Windows installation media (DVD or USB) and boot from it. You may need to access the BIOS/UEFI settings to set the boot priority to the installation media. 3. Start the Installation Process: - Begin the Windows installation process. When prompted to select a disk for installation, you should only see the single disk that is connected at this point. 4. Partition and Format the Drive: - During the installation, you will reach a step where you need to select a partition to install Windows. You can delete the existing partitions on the single disk, create a new one, and format it. 5. Complete the Installation: - Proceed with the installation on the single disk. Windows should install without issues since only one disk is connected and selected for installation. 6. Reconnect Other Drives: - After Windows is successfully installed on the single disk, you can reconnect the other drives one by one. Ensure that the RAID configuration is properly set up and recognized by the system. 7. Check Disk Management: - Once all drives are connected, you can open Disk Management in Windows to verify that all disks are recognized correctly. You can create partitions or assign drive letters as needed. By following these steps, you should be able to install Windows on the single disk without interference from other disks being detected as system disks. This process ensures that Windows recognizes the correct disk for installation and allows you to configure the system accordingly.
