please guide me about the technical information regarding my problem, and help me for the solution.
The error messages that you are recieving are " mbr" is Master boot record and the other "ntdr" is the NT directory, these are major files that Windows needs to load and work properly so it sounds like the Windows 7 SP1 disk is a burned or copied disk and doesn't contain these files because the disk is copied. Most likely you didn't buy the disk from a store and it's a pirated copy.
If your Windows 7 disk is a legitiment copy of Windows 7 then all you have to do is download SP1 from the Microsoft site.
