What Does “No Bootable Medium Found” Mean in VirtualBox?

Ubuntu 15

VirtualBox is a powerful tool that allows users to run multiple operating systems on a single machine. However, as with any software, you may encounter some errors. One common error is “No Bootable Medium Found.” This article will explain what this error means and how to resolve it.

Quick Answer

The "No Bootable Medium Found" error in VirtualBox means that the virtual machine is unable to locate an operating system to boot from. This error can be resolved by checking the storage settings, verifying the selected bootable medium, enabling EFI if necessary, using an existing virtual hard disk file, ensuring the virtual hard drive is properly configured, checking the boot order settings, and selecting the correct OS type and version.

Understanding the Error

The “No Bootable Medium Found” error in VirtualBox typically means that the virtual machine (VM) is unable to locate an operating system (OS) to boot from. This error usually occurs when the VM has not been configured with a bootable medium, or when the selected bootable medium is incorrect or not recognized.

Causes of the Error

There are several reasons why you might encounter this error:

  1. Incorrect Storage Settings: The VM might not have been configured with a bootable medium such as an ISO file.
  2. Wrong Bootable Medium Selected: The chosen bootable medium might not be the correct one for the OS you want to install.
  3. EFI not Enabled: If you are trying to run Windows from a Virtual Hard Disk (VHD), you may need to enable EFI (Extensible Firmware Interface) in the system motherboard settings of the VM.
  4. Incorrect Use of Virtual Hard Disk File: You might have created a new virtual hard disk instead of using an existing one.
  5. Improper Configuration of Virtual Hard Drive: If you have installed an OS onto a virtual hard drive, the VDI image of the installation might not be properly attached to the virtual machine.
  6. Incorrect Boot Order Settings: The VM might not be set to boot from the hard drive.
  7. Wrong OS Type and Version Selected: The VM might have been set up with the wrong OS type and version.

How to Resolve the Error

Here are some solutions to resolve this error:

Check the Storage Settings

Open the Virtual Machine window, navigate to the ‘Storage’ settings, and ensure that a bootable medium (such as an ISO file) is selected. Make sure the medium is correctly specified and appropriate for the desired OS.

Verify the Selected Bootable Medium

Ensure that the chosen bootable medium is the correct one for the OS you want to install. For example, if you are trying to install a 64-bit OS, ensure that the selected ISO file is for the 64-bit version of the OS.

Enable EFI

If you are trying to run Windows from a VHD, you may need to enable EFI in the system motherboard settings of the VM. To do this, navigate to the ‘System’ settings of the VM, select the ‘Motherboard’ tab, and check the ‘Enable EFI’ box.

Use an Existing Virtual Hard Disk File

When creating a new VM, select the option to use an existing virtual hard disk file. Locate the VDI file in your file system and select it. Avoid creating a new virtual hard disk if you are trying to run an existing one.

Ensure the Virtual Hard Drive is Properly Configured

If you have installed an OS onto a virtual hard drive, make sure that the VDI image of the installation is attached to either a virtual IDE or virtual SATA port in the VM’s ‘Storage’ settings.

Check the Boot Order

In the VM’s settings, navigate to ‘System’ > ‘Boot Order’ and ensure that booting from the hard drive is enabled. This ensures that the VM attempts to boot from the virtual hard drive.

Select the Correct OS Type and Version

When creating the VM, choose the appropriate OS type (e.g., Linux) and version (e.g., Ubuntu). Selecting the wrong OS type can result in the “No Bootable Medium Found” error.

Remember, VirtualBox does not come with pre-installed VM images, so you will need to provide the bootable medium or installation disk for the desired OS yourself. Consult the specific documentation or guides for your OS and VirtualBox version for more detailed instructions if needed.

Conclusion

The “No Bootable Medium Found” error in VirtualBox is a common issue that can be resolved by checking and adjusting a few settings. By ensuring that the correct bootable medium is selected, the storage settings are correct, and the VM is set up with the right OS type and version, you can successfully run your desired OS on VirtualBox.

What is VirtualBox?

VirtualBox is a software virtualization tool that allows users to run multiple operating systems on a single machine. It creates a virtual environment where you can install and run different operating systems simultaneously.

Where can I find the bootable medium or installation disk for my desired OS?

VirtualBox does not come with pre-installed VM images, so you will need to provide the bootable medium or installation disk for the desired OS yourself. You can obtain the bootable medium or installation disk from official sources, such as the OS’s website or official distribution channels. Make sure to download the appropriate version (32-bit or 64-bit) and follow any specific instructions provided by the OS’s documentation.

Can I run VirtualBox on any operating system?

Yes, VirtualBox is a cross-platform software and can be installed on various operating systems, including Windows, macOS, Linux, and Solaris. Ensure that you download the correct version of VirtualBox for your specific operating system.

Can I run multiple virtual machines simultaneously in VirtualBox?

Yes, you can run multiple virtual machines simultaneously in VirtualBox. The number of virtual machines you can run depends on the resources (CPU, memory, disk space) available on your host machine. It is important to allocate enough resources to each virtual machine to ensure smooth operation.
