Easy2boot is a utility that allows you to flash a USB with multiple bootable images. This gives you the option of always carrying a variety of OSes / tools for all sorts of different scenarios (debugging using a Rescue image / gparted live, install Ubuntu / Windows 10 etc. images)
Here are the contents of a E2B USB stick that I tend to carry with me and use on a regular basis.
Setting up - Adding a Linux ISO
- Download from here: https://www.fosshub.com/Easy2Boot.html
- Extract the Easy2Boot Linux archive - run the docs/linux_utils/fmt.sh script to format the USB device
- Make sure you select the right drive. Bash script doesn’t look very well written and by default it picked my internal drive!
- Copy your .iso files to MAINMENU or LINUX
- Rename the .iso to .isodefault
- Defrag the USB device:
Try to use the same scripts for formatting / defragging that you used during the initial USB flashing. There are compabilitity issues between the different versions of the tool. If you don’t have the original downloaded zip / contents anymore, it might be worth it reflashing the USB and copying over the images to the newly created partition instead.
