Usb installer

The best options for installing Live ISO's to usb on Debian today are...
1. Ventoy
2. Etcher
3. use the dd command to copy an iso-hybrid image to the stick

Ventoy

check it out at ventoy.net
Download here from sourceforge.net

To use it, install to a USB stick (will wipe it) and afterwards copy any ISO file to the 1st partition, and that's it.

The install command is like this

Ventoy2Disk.sh -i /dev/sdX  

The -L option can be used for disk label.

Etcher

Download from etcher.balena.io

dd

sudo dd if=image.iso of=/dev/sdX bs=4M status=progress oflag=sync
