HP Laptop won't boot into Windows 7
I turned my laptop off with a hard button press while it was trying to hibernate and now it won't boot up into Windows 7 (x64). I get a blue screen with the following information:
UNMOUNTABLE_BOOT_VOLUME
Stop Code 0x000000ED
I have also tried booting up in safe mode but it hangs on the classpnp.sys.
Can somebody provide a solution?

This error indicates exactly what it says - the boot volume couldn't be mounted. This may be due to file system corruption, a problem with the bootloader pointing at the incorrect partition, a problem with the physical connection to the drive, or even a problem with the drive itself mechanically.
My guess in this situation would be that your timing of the power down was lousy and your Windows partition has some problems. See if you can run a chkdsk on it and maybe if you're lucky it'll be able to fix it for you.
ShinraiI had a similar problem once. My laptop lost power while it was starting up, and it lost the file system. As Shinrai said, chkdsk may be able to fix it, but if not, there are many programs you can use to recover a hard drive. I can't remember which one I used, but they all do about the same thing. They look through the data on the hard drive for patterns, and use that to figure out where files are. All of your data is most likely still there, Windows just can't find it.
To run chkdsk on your system, you have a couple options. If you have a Windows disc, you can boot into that. Otherwise, download RC.ISO from this page and burn it to a CD. Note that this is not the same as burning a data file, you need to make sure you're burning the ISO as an image.
Once you have one of those, put it in the computer and boot from the disc. To do this, keep an eye on the bottom of the screen as it boots. Early in the boot, it will display [key] for boot options (On my HP computer, [key] is F9). Choose Boot Device, and select your CD drive. Once it boots, you will be able to choose Recover Console. You may need to log in at this point.
At the Recovery Console prompt, type in chkdsk /r. Let the chkdsk run uninterrupted until it completes. If it gives any errors, let us know. Once it finishes, type exit, and then press Enter to leave the Recovery Console and restart your computer.
SaintWackoI am sorry for the inconvenience that is causing you but unfortunately, you corrupted your master boot record. if you have a windows 7 DVD, not a restore disk you can try to repair it by running a system check disk here are some links to help you out.
