I  have installed Virtual Box and now I'm trying to set up a new virtual  machine let's try to start the new machine that we have just created.

This is the exact error that we are going to fix today it says fatal no boot-able medium found system halted.

Fix 1:

Now  let's get into the solution part, all you need either a real operating  system disk or ISO file of the operating system that you want to run in  your guest virtual machine.

If you have real OS disk insert the same and restart the virtual machine this should straightaway fix your issue.

Fix 2:

If you have already downloaded then your ISO file will present in your download folder.

If you don't have,You can download the operating system ISO file from the official website.

For Example you can see in the image below, i have downloaded file from Ubunto Official site.

Once downloaded, open Virtual Box go to settings and select storage on screen.

I could see my virtual hard disk with the machine name that I have given initially.

But  it is empty and here I have my real optical disk which is also empty  both of these are empty in my case and that is exactly the reason why I  get this error.

If you don't see any optical disk over here select  controller and tap on the little icon on top right corner to add  optical drive and select leave empty and use this empty disk for further  steps.

Select  the optical disk at the right hand side, tap on this disk icon and  choose a disk file which is nothing but the ISO file that we have  already downloaded.

Ensure there is only one optical disc and it is mounted with the ISO file go to system under boot order.

Ensure optical disk has been selected and it is on top of the order now try to start the system.

We  are now no more getting the error "no boot-able medium found" and you  can continue and complete the rest of the OS installation process as you  do in your real PC.

Once installation process completes you can  unmount or remove the ISO file from optical disk and change the boot  order to start from hard disk.

From now on for all your subsequent boots your virtual machine will pick the install guest OS from your virtual hard disk.
