When updating the BIOS version on your Dell Optiplex, Latitude or Precision system, a user may report they receive an error stating the BIOS version cannot load.
Depending on the BIOS version already installed on your system, you may have to install a specific version first before installing the latest version.

This is due to some BIOS revisions having key dependencies that must be installed first so later versions can load correctly.
Please refer to the table below to check which BIOS version needs to be installed prior to you installing the latest revision.
