i am using lenovo G580.4GB RAM,i5 processor500GB hard disc.windows 7

i am unable to start windows.when i start,it shows windows loading files....later it shows automatic startup recovery options... i used all the options(cmd,restore,system image,memory options) in that category.no suspicious programs found...but i am unable to start my windows..previously i didn't restore my system...later i tried to restore it. it shows restore was successful.later it shows windows drive as E instead of C. if I i format it,will i lost all E drive data? or its restore point is only in E drive.
can you please suggest me a solution.. without formatting the system how can I start up...
