RAW host disk access VMDK file C:\Disk2.vmdk created successfully. You need to change the information highlighted in red above to suit you. The output is as follows, which means success. In the above command, I will create a virtual disk stored in C:\Disk2.vmdk for the physical disk 2. Run Command Prompt ( Run as Administrator) and run the following command: "%programfiles%\Oracle\VirtualBox\VBoxManage" internalcommands createrawvmdk -filename " C:\Disk2.vmdk" -rawdisk \\.\PhysicalDrive2 Here, I will use the G: drive where I installed the AIO Boot. On Windows, you can use Disk Management to view all the disks on your computer. To create a virtual disk from a physical disk, you first need to determine which physical disk you want to use. Ignore this step if you use the Virtual Machine USB Boot, which will automatically create this file. To boot the USB in VirtualBox, we will create a virtual disk pointing to the physical disk and then attach it to the virtual machine. VirtualBox does not currently support 32-bit UEFI boot, you can boot USB in VMware Workstation instead.

This software will automatically create a virtual disk from the physical disk you want, then attach it to the virtual machine. The data written to this disk from the virtual machine will be saved, but the disk will be locked and you can not use it from the real machine. Currently, this software only supports Windows, you can not use it on Linux and macOS. To overcome this problem, you can use the Virtual Machine USB Boot.

Make sure there is enough free space on the disk and that the disk is working properly.

You may try to correct the error and resume the virtual machine execution. I was unable to copy the file too large, my virtual machine was stopped with an error message: An error has occurred during virtual machine execution! The error details are shown below.

However, the data written to this disk from the virtual machine will be lost. This allows you to keep using the disk on the real machine. You can create a virtual disk, it will point to the physical disk, and then attach it to the virtual machine manually. It also supports the use of physical disks as virtual hard disks, which allows us to attach and boot physical disks in VirtualBox. So you can use it to boot the HDD, not just the USB. VirtualBox is a free and lightweight virtualization software.
