hi anilkatiyar,

all windows xp installer cd's should be bootable by default.

if you need help with copying the installer cd, and making sure that the copy is bootable, then you must do the copying through programs like Nero or "InfraRecorder" InfraRecorder Portable | PortableApps.com - Portable software for USB, portable and cloud drives

please post here if this is what you need to do. goodluck
