Ventoy

Ventoy is a multi-iso USB booting tool. It allows a user to simply copy an ISO to the directory and boot from it without wiping the entire USB disk.

Sometimes, we want to initialize cloud-init for the ISO file (for example, to perform headless instllation). We can reserve a small partition for user-data:

sudo ventoy -i /dev/sdX -r 128
