I then rebooted the server using the Microsoft Server 2019 USB drive and when I got to the "Where do you want to install Windows?" screen I still couldn't see the RAID drive and neither could DiskPart.

So I created a GPT partition on the drive and formatted it in NTFS. Using Gparted I could access the RAID drive which was unallocated. So I rebooted the server using a live Ubuntu USB stick. If I then cancel the installation and select Repair your computer and access DiskPart through the command prompt the RAID disk is not listed, only drive 0 (the USB drive). Using the USB stick the server boots into the Windows Server 2019 install screens until I get to the "Where do you want to install Windows?" screen and the RAID drive is not listed as drive 1. Following the Rufus instructions I went into the server BIOS and disabled secure boot. I downloaded the latest version of Server 2019 and used Rufus to install it to a USB drive, in GPT, UEFI (non CSM) and NTFS mode.

I have two 3Gb Seagate Ironwolf drives for the other two slots but haven't installed them yet. Configuration (RBSU)System OptionsUSB OptionsRemovable Flash Media Boot. The server has 4 drive bays and I have populated the first 2 drives bays with Crucial 250Gb SSDs and set them up with the Dynamic Smart Array B140i RAID utility as RAID 1. From the System Utilities screen, select System ConfigurationBIOS/Platform. One of my schools has recently purchased a refurbished HP Proliant M元0 Gen 9 server on which I have so far totally failed to install Microsoft Server 2019.
