Run an existing operating systems in a virtual machine.

Hi VMWare Community,

I am trying to run an existing Windows 10 installation (Windows 10 LTSC 1809 installed on disk 0 partition 5) as a virtual machine using VMWare Workstation 17 Pro (17.0.1 build-21139696). VMWare Workstation Pro is running on a separate Windows 10 LTSC 1809 OS installed on a different partition on the same disk (disk 0 partition 4).

I have found technical note: https://www.vmware.com/pdf/dualboot_tech_note.pdf which indicates this should be possible but so far I have not been able to succeed.


I have removed the drive letter associated with partition 5 using Microsoft Drive Management and rebooted to ensure it is removed.
In VMWare Workstation, I have created a new custom Virtual Machine using Custom(advanced) settings and then selecting these settings for:

Virtual machine hardware compatibility: (Workstation 17.x)
Guest Operating System Installation: I will install the operating system later
Guest operating system: Microsoft Windows
Virtual Machine Name: Windows 10 x64
Firmware type: BIOS
Processors: Number of processors 2, Number of cores per processor 1
Memory for VM: 8GB
Network type: Use network address translation
I/O Controller types: LSI Logic SAS
Virtual disk type: NVMe
Select a Disk: Use a physical disk
Select a Physical Disk: Device - PhysicalDrive0, Usage - Use individual partitions
Select Physical Disk Partitions: Partition 5 (File System: Basic Data)

When I start the virtual machine I get a Network boot message with DHCP.... and then an Operating System not found message.

I have also tried creating a new custom Virtual Machine using the same settings except for:

Firmware type: UEFI.

This brings up a Boot Manager but none of the options allow me to boot the Windows installation on the disk 0 partition 5.

Any ideas on where I am going wrong? Many thanks in advance for any assistance you can give.

Kind regards
