Hi everyone,
I have a notebook and it has the Windows 7 starter installed in German language(which I don't understand it at all), and i would like to install XP in it, but i can't because it says that there was an error...can somebody tell me how to install XP??

Do you want to Dual Boot? Dual Boot Installation with Windows 7 and XP

Boot the XP CD and attempt to install to partition desired, if it errors post back the exact wording of the error.

no, i want to remove windows 7 and install XP

Notebook or netbook?
What is the make & model?

It's notebook Acer Aspire one D257

Acer Aspire one D257 is Netbook. No CD/DVD Drive.
First check for all the Win XP drivers for your hardware, on Acer website.

theog is right. You will probably have a hard time finding the drivers. If you find them, install them on a USB stick and get them from there during the XP installation.
