What means ISO file booting
ISO file booting – explained briefly
ISO file booting means starting a computer directly from an ISO image without relying on an installed operating system. The ISO is treated as a bootable drive, similar to a physical DVD or USB stick.
Instead of loading an existing OS, the system immediately starts the installer, recovery or live environment contained in the ISO file.
What happens when an ISO file is booted?
During ISO booting, the BIOS or UEFI accesses a bootable medium. If the ISO contains a valid bootloader, it is executed and the included system starts.
- The ISO is detected as a virtual CD/DVD drive (ODD)
- The bootloader inside the ISO is executed
- An installer or live system starts without an installed OS
Common use cases for bootable ISO files
Bootable ISO files are used whenever a system must be started independently of the existing operating system:
- Operating system installation (Windows, Linux, server systems)
- Rescue and recovery environments
- Antivirus and forensic tools
- Diagnostic and maintenance systems
Booting an ISO via USB stick or via hardware?
Traditionally, ISO files are written to USB sticks to make them bootable. This requires recreating the boot media whenever the ISO changes.
Hardware-based ISO booting, as implemented by IODD devices, works differently: the ISO is emulated directly as a virtual drive and can be selected at any time without rewriting the storage medium.
- USB stick: Must be recreated for each ISO, error-prone
- IODD: Select ISO and boot instantly, reusable
Booting ISO files with IODD devices
IODD devices are specifically designed to boot ISO files using hardware-based emulation. You select the desired ISO directly on the device, and the computer detects it at startup as a real bootable optical drive.
This allows multiple ISO files to be stored and used flexibly, without additional software or reformatting.
Which IODD products are suitable for ISO booting?
1) Mobile ISO booting with integrated SSD: iodd Mini PRO
The iodd Mini PRO features an integrated SSD and modern USB-C connectivity. It is ideal for storing and booting multiple bootable ISO files on the go.
2) Professional ISO booting in a 2.5" enclosure: IODD ST400
The IODD ST400 is a 2.5" SSD/HDD enclosure that reliably emulates ISO files as a virtual bootable ODD. It is well suited for professional IT environments and service scenarios.
3) Secure ISO booting with write protection: IODD ST300
The IODD ST300 is ideal when bootable ISO files need to be used securely with write protection. It is commonly deployed in support, maintenance and recovery scenarios.
