====== Install Windows as Proxmox Virtual Machine ======
I have yet to install Windows on Proxmox from the scratch... I converted the existing Unraid VM to Proxmox. The below steps outline that process and I hope to update this page with instructions for a fresh install. If not, do it on Unraid and then follow the below :D. If you are attempting to install a fresh copy, use the below Proxmox Settings and then upload the iso and go from there... should be straight forward.

===== Proxmox Settings =====
  * OS
    * Do not use any media (we will move over out existing vdisk
    * Type: Microsoft Windows
    * Version: 11/2022/2025
  * System
    * Graphic card: VMware compatible (we will add GPU passthrough later)
    * Machine: q35 9.0 (not sure why on OSX it was latest but on windows it's 9.0 (which was the latest at the time)
    * BIOS: OVMF (UEFI)
    * EFI Storage: local-lvm
    * Pre-Enroll keys: CHECKED
    * SCSI Controller: VirtIO SCSI single
    * Qemu Agent: CHECKED
    * Add TPM: CHECKED (also on local-lvm)
  * Disks
    * Just create a small blank disk, we are going to erase and replace with already built disk
  * CPU
    * Sockets: 1
    * Cores: 8
    * Type: host
  * Memory
    * 16384
    * Ballooning Device: CHECKED
  * Network
    * Bridge: vmbr0
    * Model: Intel E1000
  * Confirm
    * Don't start vm after creation
    * Finish

===== Passthrough some stuff =====
  * Wait to do the GPU until the end (or try it now, I dunno. I did the GPU after successful boot and since it was the primary GPU I did some extra stuff below)
  * Datacenter -> Node name -> VM
  * Click Hardware
    * Click Add
    * PCI Device
    * Raw Device
    * Device: Select the Device you want to add based on its address
    * All Functions: CHECKED
    * Click OK
  * I did this for USB

===== Move virtual disk over =====
  * Erase old disk
    * Go to Datacenter -> node name -> windows vm
    * Click on Hardware
    * Select hard disk to remove
    * click Detach
    * click Remove
  * Import new disk
    * move the new disk to a location that proxmox can see it (see adding share in the install proxmox section)
    * ssh into proxmox or open a shell (Datacenter -> node name, then click >_ Shell
    * go to the folder of that new disk (cd /mnt/pve/unraid/ for example)
    * rename the image to a .raw file
    * type the import command: <code>qm importdisk 202 vdisk1.raw local-lvm --format raw</code>
      * where 202 is the vm id and local-lvm is the location.
    * after complete go to the vm -> hardware and double click on the unused disk and click Add
    * go to Options -> Boot Order and set the bood order to the top.

===== GPU Passthrough =====
  * Since this GPU is in the primary slot grabbed by Proxmox I did two things that i'm not sure which fixed it
    * 1: blacklist the drivers
      * <code>echo "blacklist amdgpu" >> /etc/modprobe.d/blacklist.conf
echo "blacklist radeon" >> /etc/modprobe.d/blacklist.conf</code>
      * link: https://pve.proxmox.com/wiki/PCI_Passthrough
    * 2: check the PCI-Express check box below when adding the card 
  * Datacenter -> Node name -> VM
  * Click Hardware
    * Click Add
    * PCI Device
    * Raw Device
    * Device: Select the Device you want to add based on its address
    * All Functions: CHECKED
    * Primary GPU: CHECKED
    * PCI-Express: CHECKED (in advanced features)
    * Click OK
