USB-SD Creator made a no booteable USB Raspberry Pi 3

  • I too, am a beginner, but I tried something that worked. Sometimes windows programs with an exe extension don't work because the path is too long. I moved LibreELEC.USB-SD.Creator.Win32.exe and LibreELEC-RPi4.arm-9.1.001.img.gz to the root directory, C: . Then, the program completed.
