This article describes the procedure for performing a bare metal restore with a Generation 2 Hyper-V virtual machine.


If you are restoring a Gen 2 Hyper-V VM, a VHDX image export is the recommended restore method. Attempt a VHDX export before doing a bare metal restore. If you are unsure whether you should create a VHD or VHDX Image Export, refer to this Microsoft article (external link) for OS compatibility.

1. On, select and download the appropriate ISO (12.04 or 16.04).

2. Attach the Datto Utilities ISO to a virtual CD drive containing the desired Generation 2 Hyper-V VM template.

3. Create virtual disks for each backed up disk. Datto recommends sizing each virtual disk to be at least 10% greater than its used space.

4. Configure the VM to boot from the CD virtual drive that contains the Datto Utilities ISO.

5. Boot the VM, then proceed to the Network Configuration section of the USB Bare Metal Restore: Booting the target machine from USB article, and follow all subsequent steps presented.

If the VM fails to boot with Secure Boot enabled:

1. In VM Settings, select Security, uncheck Enable Secure Boot, then reboot the VM.
