Boot Manager Error 0xc000000f

I am using HP laptop. I was using windows 7 operating system. But for some kind of problems i thought to run a set up in my laptop. As i heard from some people that Windows 8 is better than windows 7, so tried to install windows 8. During installation i did format to my installation drive (C: drive) and start windows 8 installation. After running 51% it got stuck so i restart my laptop. But then the installation never start again. It can not be able to boot. I have tried lots of process to pair but nothing works for me. Its showing following error message every time whenever try to reinstall with windows 7, xp or 8 disk.

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: The boot selection failed because a required device is inaccessible.

What I should i do now. Please help me out.

Do you want to reinstall Win8 or Windows 7?
