Hello and Welcome to LinuxQuestions,
Your post is VERY hard to understand. Please do not use text speak, SMS language, 'phone' shorthand but spell out you words. It will be easier for us to understand you and you'll get an answer a lot sooner. It's also considered rude to ask for 'urgent' help, that is if I understood your 'plzz repy..early' correctly.
As an answer to your question, yes you can dual boot Windows with Linux, without a problem. Have a look at Google for various howtos and step by step guides.
Looking forward to your participation in the forums. Have fun with Linux.
