Is there a boot disk for the Xbox? I called an electronics shop that does mods and they say they no longer do mods for the xbox because its easier to just get a disk.

no boot disk was ever made for the xbox. they are bulls*iting you. Unless they are talking about the Linux exploit, but this isn't easy to do.

Or they may be talking about ps2's?

He may have been talking about the exploit, he was'nt talking about the ps2. But with the linux exploit can you play online.
