HEY, THERE IS PROBLEM OCCURING WHILE INSTALLING WINDOWS 7 TO MY LAPTOP. I HAVE FORMATTED THE ALL THREE DRIVES AND THEN DELETED THE TWO DRIVES AND NOW ONLY ONE DRIVE IS PRESENT OF 298 GB. BUT WHILE I TRY TO CREATE THE PARTITION BY PRESSING NEW NOTHING HAPPENS. THE FORMAT OPTION HAS GONE. AND WHILE I TRY TO TO INSTALL THE WINDOWS 7 IN THE SAME 298 GB DRIVE - IT SAYS -- setup was unable to use the existing partition because it does not contain the required free space.
