I want to use Linux on my Machine but now i am Using Windows Xp, Please any one can tell me how can i use it or if i install it on my Machine will i loose my all data in Hard Disk. Please Guide me.
If you download Ubuntu Linux you can install it as a "dual Boot" computer. I will leave Windows where it is and add itself to the end of you hard drive. The next time you turn on the PC it will ask you which operating System you want to start.
Google Ubuntu for more info. Good luck with Linux.
