Using dd

dd is a command-line utility available on Linux and macOS for creating bootable USB drives.

Steps:

1. Open a terminal.

2. Run the following command:

   sudo dd if=MiniOS.iso of=/dev/sdX bs=4M status=progress
   

   Replace /dev/sdX with the correct USB drive identifier.

3. Wait for the process to complete.
