Security Center update causing no boot in windows / resolution

Problem and a resolution in case anyone else encounters this problem.

Security Center notified me this morning that it had updated and required a reboot.  I proceeded and at the point it should be booting to my primary disk, it would just hang with a blinking DOS cursor.

After spending a few hours trying to repair the issue, I went into my BIOS setting to find that it had somehow rearranged my disk boot order.

I was not ammused.  Anyway, hope this helps somebody.

Re: Security Center update causing no boot in windows / resolution

Tony's response is correct. McAfee Security applications do not write to CMOS data locations.

I dug around the web and the two applications that I came up with that could write to the BIOS setting locations would include BIOS firmware flashing application and  over clocking applications. Both of these applications are main board specific applications due to the unique nature of this data.

I seem to recall some mother board's  allowing one to change the boot order dynamically for just the one session by pressing the drive letter while the system boots. I couldn't find documentation for this on the web though.

Thinking about this now, there is one possible explanation that I have witnessed over time. When the CMOS battery gets weak data may be lost and or corrupt. In the past you would notice that the clocks times was wrong and or your hard drive  setting were wrong. With online time servers and auto-detection for hard drives these indicators are no longer present. If the system is a few years old this is possible.

Kriz's request for more information could help isolate this issue. Could determine that make and model of the computer and or mother board, any hardware vendor system utilities installed along with the OS versions and post them.

Re: Security Center update causing no boot in windows / resolution

I totally agree with your assessment, but this was the only change made the system before reboot.  Also, I didn't perfom any keystrokes that would cause the boot order to change (if that is a BIOS feature on my system).

The PC is a Dell Studio XPS 8100 with an Intel H57 running Windows 7 x64 Home Premium.  Internet connection is cable.

Security Center is v11.6, build 11.6.435

Dat version is 6870
