Remove Linux / Debian / Gnome?

Hi my mother in law has got Linux on her dell and only Linux. And she has asked me to reinstall windows XP back on and take Linux off. But I ran the reinstall disk on the pc but nothing happened.

How can I get rid of Linux so i can reinstall?

Linux running the Gnome desktop and is ditributed by debian if anyone knows what that is!

Just like to add that i have tried just running the installer disc for windows xp but the computor still loads linux everytime.
I have no discs for linux as it was installed directly from the net. and the guy who put it on the dell, insisted it was better than windows (he was a linux programmer and my mother in law is not and struggles to do anything on the system.

When choosing a mini laptop (either Ausus EeePC or Dell), I have to choose either a Linux operating system or Windows XP operating system. What are the differences between the two systems, and which is better for a mini laptop that will be used for web-surfing and e-mail?

what is the best dell PC to work with linux OS ?

i want to buy a pc to act as a server , and i want it to be dell original , and the server software will be on LINUX , so i was wondering what is the best desktop pc model for dell to do this ?

I just received my new external hard-drive from Dell, and I just partitioned it so that I could put an emergency backup operating system on it to retrieve files from my computer that I haven’t backed up yet.

Can an external hard-drive boot operating systems such as Linux, Solaris, or LynxOS RTOS?

Just curious…

By the way, where can I get a copy of the OpenDarwin OS?
