boot el capitan iso virtualbox no bootable medium found

Now you must include/select this file as the virtual hard disk/ medium file as shown in the answers above. Wrong Boot Order: If the virtual hard disk is not selected as a boot device in the boot order list, or the virtual optical drive with the correct boot image contains the lower boot priority and is disabled, the error can arise. This file is also used if you actually want to install the particular OS on your PC/laptop. Empty or Missing Optical Drive: When there is no virtual optical drive inserted or a bootable ISO image or CD/DVD disk drive is missing, it can result in errors in the VirtualBox, such as the no bootable medium found error.

This file can be found on the website of the OS you want, and must be downloaded. An external file called the ISO or system image file is needed.This is the 'bootable medium ' referenced above. When you install VirtualBox, it does not automatically come with the ability to run all the listed operatings systems (as I used to think ). So I will try to answer it as simply as possible, for anyone in my position :. Primarily because Ubuntu had been installed on my PC by a friend, and I had zero experience there.

I remember it taking me a while even after reading them. Although I have accepted the answers above, I realize that from the point of view of a complete noob to linux and operating systems in general, the concept of images ,ISO files etc is still confusing.
