System options not set

[Gimhana]

When I start my HP Z420 workstation get error "system options not set" on black screen and need to fix that error.

most likely due to a failed cmos battery, replace it and enter the bios and set time/date save changes

and reboot, again enter bios and now select reset to defaults, save again and reboot

to enter bios,..... on power on, tap F10 or the ESC key repeatedly

cmos battery is a cr203 located by the second pci-e x16 slot (which ha a green tab)
