all servers come with DVD drives anymore. There are so many more options for installing operating systems like booting from flash drives or booting from the network that many system administrators don’t bother with DVDs. That said, if you want to install from a DVD, you need to ensure that you have a DVD drive. The drive can be internal or external.

      UEFI-based firmware

      Unified Extensible Firmware Interface (UEFI) has replaced the traditional legacy Basic Input/Output System (BIOS) at this point. I highly recommend that you choose UEFI rather than BIOS. It’ll be required if you want to use some of the advanced features like secure boot.

      Trusted Platform Module

      The majority of motherboards come with a Trusted Platform Module (TPM) chip nowadays. If you plan on doing disk encryption with BitLocker, this is a must-have item.

      Monitor

      It goes without saying that you need to be able to see what’s going on with your server when you’re installing your operating system. Windows Server 2022 requires a Super Video Graphics Array (SVGA) connection with a minimum of 1024 x 768 screen resolution. You can accomplish this by attaching a physical monitor to the server or by viewing the video stream through a KVM.

KVMs allow you to use one keyboard, monitor (video, in the acronym), and mouse to administer multiple servers. The older KVMs required you to be physically on site to use the keyboard, monitor, and mouse. Modern KVMs allow you to administer your servers remotely through a web service, and they provide similar functionality to what you would get if you physically plugged in a keyboard, monitor, and mouse to your server.

      Keyboard and mouse

      You can connect a keyboard and mouse directly to the server during imaging or you can present them to the system via a KVM. Either way, you need a keyboard and a mouse of some kind to interact with the system.

Performing a Clean Install

      Clean installs are my preferred way to go. By performing a clean install, you’re far less likely to run into issues caused by bad drivers, corrupted system files, or misconfigurations. In this section, I walk you through how to do a clean install of Windows Server 2022.

In this section, I assume that you’ve already booted to whatever media you’re going to use for the installation (DVD, flash drive, and so on), and you’re on the starting installation screen for Windows Server 2022. If you’ve done this, you should see a screen that looks like Figure 3-2. From this screen, follow these steps:

      FIGURE 3-2: The first installation screen for Windows Server 2022.

      1 Select the appropriate settings for your locality and click Next.In my example, I’ve chosen the following:Language to Install: English (United States)Time and Currency Format: English (United States)Keyboard or Input Method: USAfter you click Next, the screen shown in Figure 3-3 appears.FIGURE 3-3: The Windows Server 2022 Install Now button.

      2 Click Install Now.

      3 On the next screen, choose which version of the operating system you want to install and click Next.The default selection is for Windows Server 2022 Standard (shown in Figure 3-4). If you prefer, you can select Windows Server 2022 Standard (Desktop Experience), Windows Server 2022 Datacenter, or Windows Server 2022 Datacenter (Desktop Experience).

      4 On the next screen, check the I Accept the License Terms box and click Next.

      5 On the next screen, choose Custom.The other option is for upgrade installations.FIGURE 3-4: Choosing your desired edition and experience of Windows Server 2022.

      6 On the next screen, select the partition on which you want to install Windows and click Next.In Figure 3-5, you can see that this is Drive 0.Windows Server 2022 begins installation and restarts after it’s finished. That’s when the real fun begins!

Upgrading Windows

When considering an upgrade install, you need to ensure that the version of the operating system you’re starting with is able to be upgraded to Windows Server 2022. Table 3-1 tells you which operating systems you can upgrade from and which edition of Windows Server 2022 you can upgrade to.

      

As a general rule, you can update to the newest Windows Server operating system directly as long as you’re within the last two major releases.

TABLE 3-1 Windows Server 2022 Upgrade Compatibility Matrix

If you’re running this edition …	You can upgrade to these editions …
Windows Server 2016 Standard	Windows Server 2022 Standard or Datacenter
Windows Server 2016 Datacenter	Windows Server 2022 Datacenter
Windows Server 2019 Standard	Windows Server 2022 Standard or Datacenter
Windows Server 2019 Datacenter	Windows Server 2022 Datacenter

      You also need to check with your application vendors to ensure that the applications on the server are compatible with Windows Server 2022. If they aren’t, then you may need to upgrade your applications before you upgrade the server operating system.

      

There is no direct upgrade path from Windows Server operating systems that are older than Windows Server 2016. If you’re migrating from an older server, start with a clean installation. If you can’t use a clean installation, you’ll need to upgrade to either Windows Server 2016 or Windows Server 2019 to be able to upgrade to Windows Server 2022.

      After you’ve verified that you’re on a compatible version, you can begin the upgrade install. For this example, I’ll start with a Windows Server 2019 Standard installation and upgrade it to Windows Server 2022 Standard. Follow these steps:

      1 Log in as the administrator on the system that you want to upgrade.

      2 Insert
