Windows 7: windows boot manager

Hello

I have a windows 7 home premium 64 bit. And when i start the system i get the following message.

Boot Manager:
Windows failed to start. A recent hardware of software change might be the cause. To fix the problem:

1.Insert your Windows installation disc and restart the computer.
2.Choose your language settings, and then click "Next".
3.Click "Repair your computer."

If you do not have this disc, contact your system administrator or computer manufacturer for assistance.

Status: 0xc000000f

Info: an error occurred while attempting to read the boot configuration data

I searched the forums. But unfortunately i don have the installation disc.
Is there any other way to get through this.
Any suggestion would be appreciated.
please tell me the procedure to solve this problem,
