BIOS Update [Latitude E6430] Fails to Run / Install
After seeming to recall that I needed to step up to A11 on an E6430, I updated the unit in question from A03 > A07, without issue. However, when I went to bump it up to A09 (in preparation for A11), the process ran, but then only rebooted. I tried it again...same result. Thinking that I was missing something, I ran A11. The result was the same!? Each attempt would process without question / complaint, only to then reboot the system. :emotion-12:
I then attempted to reset the BIOS to the factory defaults. I noted a change...but it didn't appear to have reset everything!? :emotion-40:
SOLUTION: Pop the cover, disconnect the CMOS battery for about 10 minutes, and then reapply the update(s).

I also believe that whenever the TrustedInstaller user account takes ownership of the entire C:\ drive, certain applications fail to execute. Changing the ownership to the Administrators group, and pushing the permissions all the way down the tree, the BIOS installer finally worked as expected. I presume it was unable to write to the hard drive during the installation, and therefore failed.
I can only confirm that after changing the ownership and permissions of my hard drive, the BIOS installers worked.
