New computer running Windows 7, unexpected I/O error 0xc00000e9

We have a brand new computer, only 2 days old, and all of a sudden we are getting this error upon booting up:

Windows has encountered a problem communicating with a device connected to your computer
If you continue to receive this error message contact the hardware manufacturer

Status:  0xc00000e9

Info: An unexpected I/O error has occured

All I can do is hit Enter or ESC and either key causes the computer to reboot, bringing me back to the same error screen.  I have unplugged everything from the computer except the monitor, keyboard, and mouse.  What can I do?

Hi KNPeterson,

Welcome to Microsoft Answers!

The error message - An unexpected I/O error has occurred, Status: (0Xc00000e9) is a hardware error pertaining to your computer's BIOS. Basically
it is telling you that the computer is not able to reliably communicate with the hard drive.

You may try startup repair. Startup Repair is designed to prevent a time-consuming reinstallation by diagnosing and repairing problems that
prevent Windows from booting. Introduced in Windows Vista, Startup Repair is even easier to use because Windows 7 now installs it on your
hard drive for you.

Refer the links below for more details:

I also suggest you to update the BIOS. You must get in touch with the system manufacturer to update the BIOS.

Modifying BIOS settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot
guarantee that any problems resulting from the configuring of BIOS settings can e solved. Modifications of the settings are at your own risk
