sounds like you may have downloaded the wrong iso; ones with DE in the name will default to German, ones with EN in the name will default to English. See the downloading faq for more details. There is a cheat code to force a language, but there is a small catch, there is an = in the code, and the = is in a different place on the German keyboard layout, so it may take a little effort to find it. Can be done though.

any ideas ?
I though that was well covered in the faq, so I didn't retype the info here. There is one prompt during the boot. You can type the desired code or codes there. I like to type F2 at this point, it stops the automatic countdown if you do nothing, and shows some helpful information. You can then put together whatever cheat code string you want.
