My Dell Optiplex 755 BIOS/CMOS battery went flat and windows refused to boot as a result,so after i wrestled with the machine i found a solution to the BIOS reset and windows reboot issue.

Disclaimer:
This solution applies to Dell Optiplex machines,only change the settings in the BIOS if the battery has failed and at your own risk to your data.
