Windows 7 - Won't boot - 0xc0000001

A user brought his laptop to me complaining that it won't boot.

The laptop is:
Dell E5500
250GB HD
2GB RAM
Windows 7

No peripherals are attached to the laptop.

The error screen is:
Windows 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 your 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: 0xc0000001

Info: An unrecoverable error has occurred.

I was able to follow your recomendations exactly. I used a Sata to USB adaptor and scanned the disc in Windows 7.

It doesn't look like it detected any errors on the drive. I've attached a screenshot of the scan results as well as the Event Viewer entry.

This morning, booting straight off the hard disk resulted in the same error: 0xc0000001

Automatic Startup Repair returned a slightly different Problem signature:

I restarted the system and I was met with the same initial error screen:

Windows Boot Manager

1. Insert your Windows installation disc and restart your computer.

Unfortunately the problem persists.

I would very much like to avoid reinstalling the OS.

Thanks for your reply.

Have you tried these steps?

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

I know you said you want to avoid doing a total re-install of the OS but the repair install is somewhere in between and it won't mess with your porgrams/files.

Yes, I've tried those steps.

The "Repair your computer" option does scan and has said it found problems which it corrects but upon restarting, I always end up back at the 0xc0000001 error screen.

I appreciate the help. I have tried both the solutions you in your last suggestion and end up having to reimage the laptop... (time constraints and all)

Thank you for your troubleshooting ideas.
