Hi, Thank you Samson.
Cloning is the main message in your solution. Cloning of c: drive with initial programs, is the best choice, because one need not install the OS again with initial programs. And i think the registry entries are also copied if you clone. Nice solution. Eventhough, the problem is over, i thought that this is related litem in booting, so, continued with this thread instead of new one.
Anyway, as you said, i will raise a new thread on it shortly. Thanks Shane, boggins, samson and lot others who have given the ideas on how to solve the problem. Shane has given the idea that OS is independent of mother board drivers. A sound thought and solution to my problem that i could retrieve. Thanks all
