On a Linux system, you can use the cp command to write an image to a USB flash drive:
sudo cp <file> <device> Alternatively, you can use dd : sudo dd if=<file> of=<device> bs=16M status=progress oflag=sync First, use lsblk to identify your USB device. Make sure that /dev/sdX refers to the whole device, not to a partition such as /dev/sdX1. Then run one of the commands above, replacing <device> with the device name (for example, /dev/sdX): sudo dd if=debian-live.iso of=/dev/sdX bs=16M status=progress oflag=sync Please avoid UNetbootin, Ventoy, and other third-party tools, even if they are generally considered safe.
