Converting Legacy Boot to UEFI Windows 10 template

If you've got a DaDesktop machine that you'd like to use a GPU or other pass-through with, you'll need to convert it to UEFI boot first.

We still recommend using win10-template-v53 or later, but if you reckon it's more worthwhile to do the upgrade yourself, here are the steps:

  1. Enable defrag service
  2. Create boot files on C drive
  3. Set C disk as active
  4. Convert the system to UEFI
  5. Modify kvm config to support UEFI
  6. Fix DaDesktop BIOS boot option
  7. Upgrade virtio-win drivers
  8. Disable defrag service
  9. Optional: move partition in front of system partition to support automatic disk resizing
     

1. Enable Defrag service

  1. Run cmd as administrator
  2. Run:
    sc config defragsvc start= demand

2. Make C: disk bootable

  1. In an administrator Command Prompt, run:

    bcdboot.exe c:\windows /s c:

3. Set C: disk as Active

  1. Run Disk Management
  2. Right-click on the C: partition
  3. Set Active
     

4. Convert the system to UEFI

  1. In an administrator Command Prompt, run:
   mbr2gpt.exe /concver /allowFullOS

 

5. Modify kvm config to support UEFI

  1. SSH into the ddnode
  2. Make sure you run the command as root

  3. Copy OVMF_VARS.fd and qemu.conf from a template that supports UEFI boot, e.g.:

    cp /var/lib/kvm/win10-template-v51/OVMF_VARS.fd /var/lib/kvm/yourimagename/
    cp /var/lib/kvm/win10-template-v51/qemu.conf /var/lib/kvm/yourimagename/

6. Fix DaDesktop BIOS boot option

  1. Stop and start the machine using the dd4t.dadesktop.com GUI or API
  2. The system will boot into the UEFI Shell
  3. Type: "exit"
  4. Goto BootManagement TODO: FINISH IT
  5. F10 to save
  6. Exit BIOS
     

7. Upgrade Virt-io drivers

Some templates may have an outdated version of the VGA driver, which can cause issues such as being unable to change the resolution. To fix this:

  1. On your desktop, download the new version of the drivers: https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/archive-virtio/virtio-win-0.1.240-1/virtio-win-0.1.240.iso
  2. Install: TODO exact file name
  3. Reboot
     

8. Disable DEFRAG Service

  1. Run cmd as an administrator
  2. Execute:
    sc config defragsvc start= disabled

 

9. Optional: move partition in front of system partition to support automatic disk resizing

 

  1.  Boot system in Rescue mode
  2.  Use gparted to move partition in front of system partition
  3.  Reboot

10. Install Idd drivers

  1. https://github.com/ge9/IddSampleDriver
  2. Download it from here: https://github.com/ge9/IddSampleDriver/releases
  3. Extract on c:\ (otherwise it will not work
  4. Install certificate (as root)
  5. Install the driver (right clikc on .inf file and Install)
