This guide assumes you have Proxmox already setup and configured. This follows their best practices to host a Windows 2022 Virtual Machine. https://pve.proxmox.com/wiki/Windows_2022_guest_best_practices

Step 1. Download ISO and VirtIO Driver

Download the Windows Server 2022 ISO from the Microsoft website. This version of windows is available for 180 days. This fits my needs, if you require longer, purchase a license.
Download the Windows VirtIO drivers.

Upload the Server ISO to Proxmox Storage. Click local (pve) → ISO images -> Select the ISO file -> Press Upload.

Repeat the previous step for the VirtIO Driver ISO.
Click ‘Create VM’ at the top right of Proxmox. Provide a VM ID, name and select the Server ISO image from the OS tab. Select Windows as the guest OS.

Under System, enable the “Qemu Agent”. Select the relevant EFI and TPM storage.
Under Disks, change the Bus/Driver to SCSI and select your relevant storage. Under CPU, increase the cores to 2+. Under memory, increase or leave the MiB set. Depending on your use case. Confirm and save.
Under Network, select the VirtIO (paravirtualised).
Once created, click into it and view the Hardware details. Add a new CD/DVD drive and select the VirtIO drivers.

Right-click VM, Select Start, open virtual machine and wait for boot to complete (If you get a BdsDxe: failed to load Boot0001 error, press esc as soon as the VM boots).
Follow the installer steps until the installation type selection. Press Custom (advanced).
Click ‘Load Driver’ -> Browse to the CD drive where the VirtIO driver was mounted, select folder “viosci/2k22/amd64”, select “Redhat VirtIO SCSI pass-through controller”, click next to install.
Choose the drive and continue the steps.
Change administrator password when prompted.
