MultiOS-USB provides the functionality to work with a single USB drive that contains several ISO files. This means you can boot your computer from a USB stick and access different operating systems or software installations without the need for separate USB drives for each ISO file.

Advanced Users
MultiOS-USB is a specialized tool geared towards experienced users who require the capability to work with multiple ISO files during the process of reinstalling operating systems. This tool becomes particularly useful in scenarios where users are conducting experimentation with various software or system features across different iterations of the same operating system.

Using MultiOS-USB
Install and copy ISO files, then boot them from the USB. It will then display a list of currently supported operating systems. For Linux usage please see details here.

Addtional Image Writing Software Required
To successfully set up MultiOS-USB, you will need to use additional image writing software to write the 'image.img' file to the disk, like ImageUSB. You will then open diskmgmt.msc and right-click on the unallocated space to access the new volume's settings. Here, you can specify the new volume's size, file system, and label. Once you have configured these settings, you can proceed to unpack the files from files.zip onto the new disk. After that, copy the ISO files and use the USB to boot up your PC.

MultiOS-USB stands out due to its wide range of features. It supports both BIOS and UEFI systems, as well as secure Boot. Additionally, it is capable of loading UEFI drivers and launching various bootloaders, including EFI executables. The tool also allows booting from ISO and customizing the ISO boot menu. Notably, it supports the exFAT filesystem. As for accessing ISO files, MultiOS-USB offers the convenient feature of autodetection on a loopback function, which promptly identifies new ISO files.
