I made a rude mistake. Please someone help me 
I want to remove Ubuntu 12.04 from my dual boot /win7/ computer. Then I followed a video from the youtube. According to the video I must choose the option EasyBCD->BCD backup/repair-> Re-create/repair boot files.
But I chose EasyBCD->BCD backup/repair->reset BCD configuration without realizing.
I have tried to install again win7 by windowss installation disk. Nothing happened.
windows boot manager is keep displaying
File:\Boot\BCD
Status: 0xc0000098
Info: This windows boot configuration data file does not contain a valid OS entry.
I also continuously press F8. The result was only loud beeping sound that only stops press shutdown button.
What should I do?
