Ubuntu VirtualBox No Bootable Medium Found System Halted: A Common Issue with a Simple Solution

Are you frustrated with the 'No bootable medium found! System halted' error message when trying to run your Ubuntu virtual machine (VM) on VirtualBox? You're not alone. This issue is more common than you think, and in this article, we'll explore the causes and provide a simple solution to get your VM up and running.

Firstly, it's essential to understand that VirtualBox VMs default to using a Legacy BIOS environment. If you've set up your VM to boot in UEFI mode but haven't explicitly changed this setting, it can cause compatibility issues with your operating system.

To resolve the 'No bootable medium found! System halted' error, you need to ensure that your VM is set up to boot in UEFI mode. Here's a step-by-step guide to help you achieve this:

1. Launch VirtualBox and navigate to the settings of your Ubuntu VM.

2. Click on the 'System' tab and then select 'Motherboard.'

3. In the 'Boot Order' section, ensure that the 'UEFI Firmware Settings' option is enabled.

4. Save your changes and restart your VM.

If you've already tried running Fix Boot Problems when your Rescue Media was booted in Legacy BIOS mode, it's likely that you'll need to re-run this process after switching to UEFI mode. This will allow the necessary fixes to be applied to your Windows environment.

Additionally, if you're experiencing issues with getting your VM to boot into the Rescue Media ISO, you may want to try running ReDeploy. This tool can help resolve any problems with your VM's boot configuration.

In conclusion, the 'No bootable medium found! System halted' error is often caused by VirtualBox VMs defaulting to Legacy BIOS mode. By following these simple steps and ensuring that your VM is set up to boot in UEFI mode, you should be able to resolve this issue and get your Ubuntu virtual machine running smoothly.
