Getting the “No Bootable Medium Found” Error in Virtualbox?

Virtualbox is a great application that allows you to run different operating systems on your computer. You can have Windows on your computer as the primary OS while having the option to run different operating systems on Virtualbox. The benefit of using Virtualbox is that you don’t need to partition your hard disk manually. Virtualbox does all the necessary settings by itself. 

Nevertheless, there isn’t to say that Virtualbox users don’t encounter errors. An error message that you may receive is “No bootable medium found”. 

The error in question is pretty common and is related to Virtualbox only. There are different reasons why users get this error message, but each can be solved easily. 

If you were on the receiving end of the “No bootable medium found” error in VirtualBox, then fear not, as this guide will help you get rid of it. We will guide you step-by-step on how to troubleshoot the error and resolve the problem with ease.

As stated earlier, there are various reasons why a user might get this error. We shall discuss the most prominent reasons for this error along with methods to resolve it.

So buckle up and let’s begin!

Reason 1: Incorrect Bootable Disk Created.

Virtualbox requires an ISO file or a CD/DVD to boot an OS from. An ISO file is a disk image file that contains all the data of an optical disk (CD or DVD). Complete operating systems can be converted into an ISO file, and that file can be used by Virtualbox for booting. Similarly, CD/DVD can also be used to store an operating system and for booting purposes.

The error occurs if the ISO file being used is corrupted. In the case of a CD/DVD, if they were being burnt as a data disc without selecting the “Bootable Disc” option, then they can not be used to boot an OS. 

To check that you are facing the above-mentioned problems or not, you can do the following:

  1. Burn another data disc and create it as a Bootable Disc. After burning, start your virtual machine. If it works, your data disc was not a bootable disc.
  2. Create another ISO file and use it to boot your OS on Virtualbox. If your machine works and you don’t receive the error, your ISO file was corrupted.

If your operating system works just fine after following either of the steps, then be at ease as you’ve resolved the issue while understanding the error. If this doesn’t solve the problem, however, we shall move on to troubleshoot for the next reason.

Reason 2: Virtual Optical Drive is Empty or Doesn’t Exist.

Virtualbox as the name suggests is a virtual computer. Just as a computer has CD/DVD drives, Virtualbox comes with its virtual optical drive. This is where the user has to either attach the ISO file or select a host drive containing the bootable CD/DVD. 

You can come across these two situations when you either fail to create an optical drive for the OS you are trying to run or fail to load any resources in the optical drive after creating it. But need not worry, both can be easily rectified. 

Follow these steps for successfully creating an optical drive and attaching relative resources: 

  1. Open the Virtualbox application.
  2. Right-click on the machine you want to modify and select Settings.
  3. Next, go to the Storage option and select the relevant storage device.

After successfully executing these steps, you should be able to make your virtual machine work. In case this doesn’t work either, you can search and apply fixes for the reason mentioned below.

Reason 3: Incorrect Boot Order.

Selecting an incorrect boot order is another reason that you may receive the error message. This happens when the virtual drive where the OS is situated is selected as a boot device, and the virtual hard disk is not selected as a bootable medium. 

This can also happen when the drive containing the OS is selected in a lower boot order position. If you have done this, it can easily be corrected, and you can then use your virtual machine as it should work.

Follow these steps:

  1. Open the Virtualbox application.
  2. Right-click on the machine you want to modify and select Settings.
  3. Next, click on the System option.
  4. Select the Boot Order as shown in the image below.
