How to cancel XP installation setup which got stuck at "Installing Devices"

Hi,
My system got stuck at "Installing Devices" while doing reinstallation of windows XP.

Please help me how can I cancel the setup and come back to the main blue screen which comes when the installation CD is inserted into the CD drive.

Desperately looking forward for somebody's help.

Thanks,
Kiran.

You can simply remove the installation disk from your CD drive, restart the computer and insert CD. Change BIOS settings to boot from CD and start the process again. It is just simple.
