MultiBoot USB
This is a collection of GRUB scripts that allows to create a bootable pendrive (USB dongle, flash stick) supporting a number of different OS images. Simply copy ISO files under `/iso-imgs`. Both UEFI and Legacy BIOS boot modes can be enabled simultaneously.
In this boot CD are the most popular and useful tools anyone would ever need. The best of the free software, the best of the commercial software, and it all fits on one CD-R that’s readable by any computer worth booting on. Not everything can read a DVD, and USB booting is hit and miss at best.
