How to Boot Linux ISO Images Directly From Your Hard Disk Drive
Booting Linux ISO Images on your hard drive is useful for testing new versions of linux distributions without using up a CD or USB Flashdrive. It is quicker than using a Live USB Creator such as rufus, balena etcher or unetbootin.
This tutorial requires you have a Linux system installed on your hard drive example: Ubuntu. Your computer must be using the GRUB2 boot loader, which is a standard boot loader on most Linux systems.
Download the Linux ISO images files you want to use and store them on your Linux partition. GRUB2 should support most Linux systems. if you want to use them in a live environment without installing them to your hard drive, be sure to download the “live CD” versions of each Linux ISO. Many Linux-based bootable utility discs should also work.
