Restoring default manufacturing settings
The difference between this action and the Restore Default System Settings option is that Restore Default Manufacturing Settings erases all UEFI variables. An OS can write UEFI variables that store such things as entries in the boot order and key database information for Secure Boot. When you Restore Default Manufacturing Settings, this information is cleared, whereas it is retained when you Restore Default System Settings.
To save a custom default configuration to use during a system restore, use User Default Options. Doing so saves settings you might otherwise lose.
Procedure
- From the System Utilities screen, select .
