PlayStation 2 Slim detects my DVD as PlayStation 2 disc

I recently bought a Sony PlayStation 2 game console (model-no SCPH-75004, DVD-player version 3.11E. I want to install FreeMcBoot, but when I insert a burned FreeDVDBoot DVD-disc into my PlayStation 2, it detects my DVD as a PlayStation 2 disc. When I hard-reset the PS2, the DVD spins but there is black screen. I finalized the disc, but the black screen occurs again.
