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.
Ultimate Boot CD allows you to run floppy-based diagnostic tools from CDROM drives and consolidate as many diagnostic tools as possible into one bootable CD. An experimental feature also allows you to run UBCD from your USB memory stick on newer machines that supports booting from USB devices.
