It was showing 64-bit operating systems as one of those options in VirtualBox but you don’t know why there are only 32-bit versions listed below. There are two issues here. You either have Hyper-V turned on, or have Intel Virtualization Technology disabled in BIOS. If you have one of those settings configured as mentioned, this is the reason.

• Oracle Virtualbox Windows 10 32 Bit Download

• Click Here: Download Windows 32 Bit ISO. Click Here: Download Windows 64 Bit ISO. Step 2: Download and Install Virtualbox. Download the latest version of Oracle VM VirtualBox which is the free virtualization tool that helps you run Windows 10 on your device. Oracle VM Virtualbox is a free open source software. Go through the entire installation.
• How to Install Oracle VM VirtualBox on Windows 10 If the issue is with your Computer or a Laptop you should try using Restoro which can scan the repositories and replace corrupt and missing files. This works in most cases, where the issue is originated due to a system corruption.
• 4 Type a name (ex: Windows 10 build 10166) you want for the Windows 10 virtual machine, select Microsoft Windows for the type, and select Windows 10 (32-bit) or Window 10 (64-bit) for what version of Windows 10 you are installing in VirtualBox, and click/tap on Next. (see screenshots below) 5 Select the amount of memory (ex: 4 MB or 4096 KB) in.

How-to convert a (UEFI-based) Windows 10 physical installation into an Oracle VirtualBox guest.

You will need Windows 10 installation .iso to complete this guide. Don't forget to make sure you are licensed properly as well.

5 Steps total

Step 1: Create a VHDX/VHD

You will need to run (as administrator) SysInternal's Disk2vhd on the computer you are converting
Download Disk2vhd from https://docs.microsoft.com/en-us/sysinternals/downloads/disk2vhd

Simply select where you want to save the file to and click 'Create'

Step 2: Convert VHDX to VDI

On the computer you have Oracle VirtualBox installed run the following command in Powershell (as administrator). You will need to run this command from the directory that VirtualBox is installed to i.e. C:Program FilesOracleVirtualBox

./VBoxManage clonehd .vhdx .vdi --format VDI

Step 3: Create a Virtualbox VM

Create a New VM from within VirtualBox Manager and choose 'Use an existing virtual disk file' which points to your newly created VDI file.

After it is created open Settings for the VM.

Under System > Motherboard make sure only Hard Disk and Optical is selected, Optical is at the top of the boot order and 'Enable EFI (special OSes only)' is ticked.

Under Storage, point the optical drive to the Windows 10 installation ISO.

Configure the rest as you please.

Step 4: Boot VM to Optical Media

Once you have booted to the installation media and it is asking for 'Language to install,' etc, press Shift+F10. This will open a command prompt.

In the command prompt run 'diskpart'

Enter the command: 'list vol'

This will list off the volumes and should show Volume 3 as a RAW FS. You will need to format this EFI partition. Use the following commands

'sel vol 3'
'format quick fs=fat32 label='System'

If you enter 'list vol' again you will see the changes made.

Exit diskpart by entering command 'exit'

Run the command 'bcdboot C:Windows' which will add the required boot records.

Step 5: Restart VM to Disk

You can now close out of the installation media and restart. On restart make sure you don't boot from the Optical drive again and it should boot into Windows as expected.

You have now converted your physical Windows 10 UEFI device to an Oracle VirtualBox VM.

Below I have added a reference to doing this in Hyper-V, which is part of what I followed to create the above guide. I have also added a reference to licensing requirements as suggested by a comment.

  Make sure it's licensed properly when you do this.

  I was just about to write my own tutorial on this same subject. We still have some Fire Control Panels that MUST talk to a Win XP for programming and nothing else. I have been converting a Win XP dual boot to a VHD for use in Oracle VM for this issue. Great write up.

  Just read the licensing post. I didn't realize that Chris spoke Chinese. I assume the licensing info was written in Chinese because I couldn't make heads or tails from it.

  This is a neat guide, VMware has a free software that can do this as well.

  This was my missing step (diskpart and bcdboot) for migrating a bare metal server (Server 2012) to KVM. Volume names were different, but that was easy to re-interpret.

  I did this step by step in a lab environment and it went perfect. Good to learn for future use. Thanks!

  Nice write up. I'm assuming this is just a test machine, or maybe something being used for OS deployment/builds?

  This was originally a request from a customer because they needed to be able to access an old database for a piece of hardware they were replacing. In the end it turned out we only needed to backup the database and keep a copy. The person installing the new piece of hardware had no idea about how the software (they were supposed to be experts with) worked.

  I have Windows 10 running on VirtualBox, but it seems to be running a little slow. Any tips on how I can speed it up? I'm running Windows 7 on a dual boot MacBook Pro late 2011, with an i7 and 8GB of ram. I tried it on Workstation Pro 15, and still slow. Any help will be appreciated.

  Thank you.

  Good article. I haven't used Virtualbox in a while. I'l take another look at it.

  Feeling embarrassed... having an brain freeze...I am not seeing anything about step 4. It looks like the virtual is running, but I do not see any display, just a black screen.

  @dtrade84
  Your laptop will support 16GB of RAM. I would consider maxing it out and running the Windows 10 instance with 8GB of RAM.

  Step: 4: Boot VM to Optical Media does not work for me.
  I can't change boot to ISO
  ISO works perfectly fine, I used it to make a new W10 in VB.

  Please Help
  Best regards
