please help me :cry:

I'd guess you've burnt your cd or dvd incorrectly, instructing your software to create a bootable media, haven't you - hence the dos nonsense you're seeing. You should burn as image - please check the FAQ.

The dr_DOS prompt is usually a sign that you didn't follow the instructions in the FAQ, took an option in NERO to make the disc bootable, and now have a mucked up disc. But your statement about having some sort of prompt with Knoppix in it conflicts with that. Still, my best advice is to suggest you follow all the instructions in the Downloading FAQ.

yes It's true!!!!!

I Made a Mistake burning cd as a bootable cd.
now I correctl burned cd and everything goes OK!!!!!

I really thank you guys for your attention and support to my trouble.

thank you very very much
