In order to install Server 2019 Standard, first you have to download the server standard 2019 ISO file and create a bootable flash drive or burn it on a dual layer DVD.

It took a while to create a bootable flash drive and after I finally was able to create it, when I was trying to boot from it I was unsuccessful. So I had to find a workaround.

I took a USB flash drive with a bootable Windows 10 installation and boot the server from it and in the same time I connected the other USB flash drive that had the files to install windows server 2019 Standard. After booting from the first flash drive, I opened the command prompt and navigated to my drive that had the installation files for the Server OS and run the install.exe file.

The next problem that I run into was that the install didn't recognize my drives that were setup in RAID 1. I had to download the file SAS_RAID_DRIVER_WS2019_S140_5.5.2-0008_A00_ZPE.exe and extract it. I moved the files to one of the flash drives and installed the RAID drivers on the server.

Afterwards it was just the standard OS install steps.
