In today’s digital age, installing operating systems or running live environments from ISO files has become a common practice. However, the traditional method of creating a bootable USB drive can be time-consuming and may not always be feasible. Fortunately, there are alternative methods to boot from an ISO file without using a USB drive. In this article, we will explore the various ways to achieve this, including using virtual machines, mounting ISO files as virtual drives, and utilizing specialized software.
Understanding ISO Files and Booting Process
Before diving into the methods, it’s essential to understand what ISO files are and how the booting process works. An ISO file is a disk image of an optical disc, containing all the data and file system structures. When you create a bootable USB drive, the ISO file is extracted, and the necessary boot files are configured to allow the computer to boot from the USB drive.
The booting process involves the following steps:
- The computer’s BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) firmware is loaded.
- The BIOS/UEFI searches for a bootable device, such as a hard drive, USB drive, or CD/DVD drive.
- If a bootable device is found, the BIOS/UEFI loads the boot loader, which is responsible for loading the operating system.
- The boot loader loads the operating system, and the computer boots up.
