Windows 7: Windows failed to start! After Reformat Status: 0xc000000f

Windows failed to start! After Reformat Status: 0xc000000f

I have a Windows 7 home professional 64bit. Its a gateway NV55S17U. And when I start the system I get the following message.

Boot Manager:
Windows failed to start. A recent hardware or 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.

The error occurred after using reformatting my computer.] I did not have the recovery disc so I ordered one from Acer for the gateway. I inserted the recovery disc 1 of 3 and booted up my computer again. It did not recognize the disc and the dame boot message above appeared. I tried to change the boot order for the CD/DVD disc drive and make it the first device booted. That did not work either. All help is appreciated.

The disks Acer shipped reinstall all of the factory crapware which corrupts and interferes with better versions built into Windows 7. That's why tech enthusiasts won't run such an install but prefer to do the superior Clean Reinstall - Factory OEM Windows 7. Everything you need is in the blue link to get a perfect install, including the latest official installer with SP1.

To try to repair the existing installation work through these steps for Troubleshooting Windows 7 Failure to Start which also provides all the necessary boot disks to disinfect, repair or reinstall.

To try to force the Factory Recovery disks to boot and run you may need to boot the provided Windows 7 installation DVD or System Repair Disk to wipe the HD with Diskpart Clean Command first.
