Under Attributes, select your Live CD image and tick the 'Live CD/DVD' checkbox.

Go to 'Storage' and select the empty disk IDE controller.

Make sure that you assigned only 1 core of CPU to ReactOS VM.

You can either make a new one, or choose an existing one (if formatted it must be FAT16/FAT32). A hard drive is required for booting the system.

Add a Virtual Hard Drive, even if you wish to run from CD.

Choose the amount of RAM you wish to allocate to the Virtual Machine.

The version should be set to Windows 2003 (32bit).

Enter a name and set the type to Microsoft Windows.

The process is demonstrated using VirtualBox 4.2.14 r86644 on Windows 7 圆4, but it should be similar on other operating systems, and versions. The following instructions will guide you through the process of creating a ReactOS compatible virtual machine in VirtualBox, and mounting the Live CD. You need to use the full installation image, which is called ReactOS BootCD. Note: You can't install ReactOS from the Live CD. (Quickly access it by pressing Win+ R and typing appwiz.cpl) when attempting to start a Virtual Machine ensure both Hyper-V and Windows Sandbox are unchecked in the 'Turn Windows features on or off' section of the Add/Remove Programs control panel applet. Note: If you get the error Raw-mode is unavailable courtesy of Hyper-V. Note: If you have any trouble 'capturing' your mouse/cursor within the Ros-VM-window with VirtualBox, first go to the 'machine' tab and then select 'Disable mouse integration', then click again on the VM-session you're running to 'capture', and this time it should work. VirtualBox 6.x branch is still very buggy and unstable, causes fake regressions to be found in ReactOS. Note: VirtualBox 5.2.44 version is highly and strongly recommended.
