Put in the Windows 7 DVD into the drive and click repair installation. Then again click Repair boot

^ yes bro , Now it has come ( I have already updated the thread )
But could u guess what was the cause for that ??

See if this might have been the cause of the problem -
0xc000000e error on fresh win7 install - Tech Support Forum

At first, when I saw that screen on my machine, I was scared, and I went through the "Repair your computer" option. Wited for 10 minutes, but it was too slow, so I restarted the machine, & guess what it worked! No error message again!!
Now whenever I see that screen, I just restart manually. After restart, it works flawlessly.

Don't know the reason though.
