If i shut down my machine it can only start after a startup repair. However, if i hibernate it starts normally. What this means therefore is that i am no longer able to install new updates successfully especially those that require a shut down for a complete successful installation. What should i do?
Startup Repair is the first of several Windows 7 System Recovery Options. Startup Repair basically Fixes certain problems, such as missing or damaged system files, which might prevent Windows from starting correctly at a given time.
From what I gather, your MBR might be damaged. Here is what I will suggest you do. Use the /fixmbr option in Bootrec.exe tool from the link below and that should do the job.
