Configuring VirtualBox for Windows 10 Installation

Before proceeding with the installation of Windows 10 in VirtualBox, it is essential to configure the virtual machine (VM) settings appropriately to ensure optimal performance and compatibility. These configurations include allocating sufficient system resources, setting up storage, and adjusting network options.

Begin by opening VirtualBox and selecting New to create a new virtual machine. Enter the name for the VM and select Microsoft Windows as the type, with Windows 10 (64-bit) as the version. This selection enables VirtualBox to apply default settings optimized for Windows 10.

Next, allocate memory (RAM) to the VM. It is recommended to assign at least 4 GB (4096 MB) of RAM to ensure smooth operation, though the exact amount depends on your host system’s capacity. Allocating too little memory will result in poor performance, while assigning too much may affect the host OS stability.

When creating the virtual hard disk, choose the VDI (VirtualBox Disk Image) format for compatibility and flexibility. Opt for a dynamically allocated disk, which grows as needed up to a predefined maximum size, saving host disk space initially. Allocate a minimum of 50 GB to accommodate Windows 10 and essential applications comfortably.

Adjust the system settings under the System tab:

  • Motherboard: Enable EFI (Extensible Firmware Interface) if you plan to use UEFI boot for Windows 10. Otherwise, leave it unchecked for legacy BIOS boot.
  • Processor: Assign at least two CPU cores to improve performance, ensuring your host CPU supports virtualization extensions (VT-x or AMD-V).
  • Acceleration: Ensure hardware virtualization features are enabled for improved speed.

Configure the Display settings to allocate sufficient video memory, typically 128 MB, and enable 3D acceleration if needed for graphical applications.

Under the Storage section, attach the Windows 10 ISO image to the virtual optical drive. This ISO will serve as the boot media during installation.

Network settings should be set to NAT by default, which allows internet access within the VM without additional configuration. For more complex networking scenarios, such as bridging the VM to the host network, select Bridged Adapter.

The following table summarizes recommended VirtualBox VM settings for Windows 10 installation:

Setting Recommended Value Notes
Operating System Type Microsoft Windows 10 (64-bit) Ensures default compatibility settings
Memory (RAM) 4096 MB (4 GB) or higher Depends on host system capacity
