We're having a problem booting a laptop, which I don't think is malware. At least my anti-virus scanner does not find anything, and the computer otherwise is running fine once booted. One day the laptop was left on while unplugged and the battery drained, and ever since it has not booted properly. I can never shut it down without having to go through a repair process, and so I just let it sleep instead of shutting down.
Upon booting, Windows Boot Manager says:
Windows failed to start. A recent hardware or software change might be the cause. To fix the problem: .... 3) Repair you computer.
Info: An error occurred while attempting to read the boot configuration data.
Then I insert the Windows Installation disk, and it tells me to hit any key to boot from the CD/DVD. Windows then loads the files, and the prompts to install the language and keyboard format, and then it prompts to either install Windows Vista or "Repair your computer". System recovery options says "Windows found problems with your computer's startup options"... and I click "Repair and Restart". Then it restarts and boots fine. But then next time I shut it down, it fails to reboot again.
Thank you in advance for any help with this problems.
