    How to Run Docker on a Windows 10 Hyper-V Virtual Machine


    You want to have an environment with Docker for development and testing  without interfering your stable machine.


    You have enabled Hyper-V, created a virtual machine and install Windows 10 to the virtual machine.
    When installing Docker in the virtual machine, Docker requires that the Nested Virtualization feature must be enabled for the virtual machine.
    You open PowerShell, execute below command in the virtual machine:

    Get-ComputerInfo -property "HyperV*"

    You find that find that the HyperVRequirementVirtualizationFirmwareEnabled feature is not available.


    1. Download this PowerShell script. The main interesting command in this script is the command below that enables Nested Virtualization for a virtual machine.

    On the host machine execute below command:

    Set-VMProcessor -VMName $vmName -ExposeVirtualizationExtensions $true

    2. Open PowerShell as Administrator and execute 2 commands below.

    Set-ExecutionPolicy -ExecutionPolicy "Unrestricted"
    .\Enable-NestedVm.ps1 "Windows 10 Dev"
    "Windows 10 Dev" is the virtual machine name without quotes.

    3. Install Docker. Restart the virtual machine.

    4. Install any additional software if needed, restart the virtual machine again.

    5. Open a Command Prompt and test Docker installation.

    docker pull hello-world && docker run hello-world
    Rerun the command if you get an issue in the first run.



    How to Install a Fresh Windows Booted from UEFI Secure Boot using a Bootable USB


    Most of Windows machines are delivered with a limited Windows version and unnecessary preinstalled software.

    You want to format the hard drive and install a fresh Windows that can be booted from UEFI secure boot to improve machine performance and stability.


    You need to have a 8Gb USB stick and an ISO file of Windows 10, version 21H2 or Windows 11, version 23H2.


    Step 1: Backup your machine and create an USB recovery by entering “Create a recovery drive” text to the search box on the task bar and follow the instructions.

    Step 2: Create a bootable USB with Windows installation files.

    If you plan to install Windows 11 then you can use Windows 11 Installation Assistant to create a bootable USB (click Download Now link below Create Windows 11 Installation Media section), and skip the commands below.

    If you plan to install Windows 10 then you can use the commands below to create a bootable USB.

    • Right click Windows logo, click Command Prompt (Admin).
    • Enter diskpart.exe, press Enter.
      DISKPART> list disk
      DISKPART> select disk 1 -- the USB disk should be selected, the number may be different in your machine.
      DISKPART> clean
      DISKPART> create partition primary size=1024
      DISKPART> select partition 1
      DISKPART> active
      DISKPART> format quick fs=fat32
      DISKPART> assign
      DISKPART> create partition primary
      DISKPART> select partition 2
      DISKPART> format quick fs=ntfs
      DISKPART> assign
      DISKPART> exit
    • Double click on the Windows ISO file to create a virtual drive.
      xcopy f:\sources\boot.wim d:\sources\ /s /e
      f: the virtual drive and 
      d: the USB fat32 partition.
      We copy only the f:\sources\boot.wim file to d:\sources\.
      robocopy f:\ d:\ /IS /S /XD sources
      f: the virtual drive and 
      d: the USB fat32 partition.
      We copy everything from f:\ to d:\ except the sources folder.
      xcopy f:* e:\ /s /e 
      f: the virtual drive and 
      e: the USB ntfs partition.

    Step 3: Install Windows.

    1. Plug the USB to a machine.
    2. For a Dell laptop, power on the machine, press F12 until a one-time boot up menu appears. Select the option to boot the machine from the USB. (You may need to access BIOS to select the UEFI option for Boot Sequence, and select the AHCI option for SATA operation).
    3. For a Sony VAIO laptop, power off the machine, then press the Assist button to enter VAIOCare. Select the option to boot the machine from the USB. (You may need to access BIOS to enable the option to boot the machine from an USB).
    4. For a ThinkPad laptop, power on the machine, press F12 until a one-time boot up menu appears. Select the option to boot the machine from the USB. Alternatively go to Settings > Update & Security > Recovery, click the Restart now button under the Advanced setup section and follow the instructions to boot the machine from a USB.
    5. Follow the instructions to install Windows. Set Windows partition size to 614516Mb for DellPrecision if you want to have 600Gb C drive, or 262260Mb for DellXPS if you want to have a 255Gb C drive, or 819815Mb for ThinkPad if you want to have a 800Gb C drive.
    6. You can delete all the partitions, including MRP (Microsoft Reserved Partition – this is just a reserved partition for Windows later use if needed), ESP (EFI System Partition – this is where UEFI firmware files are stored to boot Windows), WINRETOOLS (Windows Recovery Environment (WinRE) Tools – this is where files for repairing or recovering Windows are stored), and PBR image (this is where original the manufacture Windows installation file  are stored) because you already created an USB recovery in the Step 1.

    Step 4: Configure Windows for Developer’s needs.

    1. Change Computer Name, turn off System Restore, enable Remote Desktop,
    2. Change Time Zone.
    3. Add Wireless LAN Service feature for Windows Server 2019.
