Unable to enable Secure Boot on Dell G5 SE 5505
I am trying to enable Secure Boot on a Dell G5 SE 5505. When I open "Select Secure Mode" it only gives me the option of "Audit Mode". The BIOS also lists as the Secure Boot Mode currently being in "Audit Mode". I've tried restoring BIOS defaults, resetting CMOS, reflashing the BIOS to the current version, reinstall Windows, and changing quick boot mode. I've also tried changing the registery key in ""HKEY_LOCAL_MACHINE>SYSTEM>Setup>Status" for Audit Mode.
Here's an image of what I am seeing in the BIOS:
Does anybody have any idea on how to enable Secure Boot on a Dell G5 SE 5505 and exit Audit Mode?

reboot
look into the bios

now you can highlight
Secure Boot an set it to
Then Save and exit !!
reboot
look into bios it shows:
Secured Boot Database < installed and locked
Secure boot status
secured boot mode
user customized security < no

That doesn’t have anything to do with the BIOS and Secure Boot. What that link is for is deploying Windows images in an enterprise environment.

Any luck @givemeflac I am also stuck with the same issue. Once I switched to "audit" then other option are gone. I even tried reverting to older BIOS but also didn't helped.

I haven't gotten secure boot to work again yet either. I also tried re-flashing the BIOS as well and that didn't work either. The BIOS recovery mode doesn't work to reenable secure boot as well.
I'd suggest asking over at the DellG5SE subreddit. They've been pretty good at coming up with solutions to fix Dell's mistakes with this laptop: DellG5SE (reddit.com)

@Aufsteller
As I said, mine is set to Legacy so I can't test it.
But from what you posted it seems to be Locked/Disabled. "Delete All Keys"
Sorry but I'm not sure what your next step should be???
Regards,
U2

I set the Option
reset all keys
and do a reset
the option
delete all keys
i do not changed to enable! I thought reset is better and more secure than delete....

I can confirm that this works. Secure Boot is now enabled again. Thank goodness I’ll be able to install Windows 11 when it comes out now!
