Hello Friends! I did this and was able to boot my newly created Debian 11 live USB but was stuck in a black terminal-like screen where it says, I/O error, etc.
Using GParted, I created an MS-DOS partition table and formatted the USB stick in fat32. Then I used these commands sudo cp debian-live-11.0.0-amd64-standard.iso /dev/sdb sync All seemed fine until I booted the live USB and got the error message as stated above. Thank you for your time.
