Step by step – how to boot from iso file in Virtual Box.
Before we configure from where we would like to boot, we must have the machine ready:
Click Settings, go to Storage Option. Its empty as of now.
Select IDE Primary Master, from Choose Virtual Optical Disk File, browse the iso file. It will display like below.
Select the iso file and you will see iso image has been selected.
Click OK and Start the VM.
Hope it helps…
