EasyOS is available as an ".img" file, to be written to a USB-stick or SD-card, which is then "booted up" on the PC. EasyOS is no longer available as an ".iso" file for optical media.

Optical media should be considered as deprecated. It is very slow to boot, is read-only and has very low storage capacity. The ISO file format should also be considered as deprecated. Although an ISO file can be written to a USB-stick and booted, this is not an installation, it has most of the limitations of booting from optical media.

On the other hand, an ".img" file written to a USB-drive or SD-card is a ready-to-use installation. It boots fast, and can be run indefinitely from the USB-drive, no need to do anything to the internal hard drive.

There are various free tools for writing the ".img" file to a USB-stick. For Windows, there is USB-Image-Tool. For Linux, there is EasyDD, or you can do it from a terminal using "dd".

Note, there is a multi-platform tool named Etcher, that you may use with Windows and MacOS, however Barry no longer recommends it with Linux.

If you already have EasyOS, running on a USB-stick or installed on an internal drive, it is very easy to upgrade to the latest version:
