Examples how write an iso to your USB via CLI, prior to installing a new OS to your computer. Use lsblk to ensure your target is sdX1, all examples reflect my twin disk set up, if for example you have a latop, 9 times out of 10 it will be sdb1, unless it uses a modern NVME SSD, which /dev/nvme0n1p
the USB is sda1, BUT check...!
Also check the actual name of the iso, for example the Debian Netinstall used is out of date, as are other list examples as they usually include a date or version number.
