Found that selectively removing individual keys had no effect on ability to boot from USB Device with BionicDog64.iso.
(Although at least the USB Drive is seen by the bios, it will not boot the .iso.)

(Bootable USB BionicDog64.iso was created with unetbootin, on LM18.3.
Same Bootable USB BionicDog64.iso was confirmed to work on Dell Inspiron 32bit.)

After all the KEYS were removed, a new menu selection appeared allowing me to restore the KEYS without the 'USB Drive with stored KEYS'.
So maybe the KEYS are not deleted, just disabled, athough this is not indicated in the BIOS.

After KEYS were restored, thus restoring the parameter: Secure Boot <enabled>,
I tried adding admin and user passwords in BIOS.
(This was suggested as a solution to toggle off Secure Boot <enabled>.)
This had no effect on the state of Secure Boot <enabled>.

That's as much as I can do until someone else has more experience with this BIOS, and communicates a solution.
At this point, any Puppy's are excluded from running on this 64 bit laptop.

Edit: If deleting keys, just save keys out to empty USB device beforehand anyway, just in case.
I think there is a difference between deleting keys individually, and 'Deleting all keys to enter Setup Mode'.
The latter I think, allows you to re-instate all keys from the BIOS only, the former requires you to import keys from a USB device.

The Bootable USB Drive however IS seen in the BIOS, just will not boot even when selected as the preferred boot media.

Does it do anything at all?
You do what?
You see what?

Specifically what you see could be a clue?

In my other laptops, all 32 bit, I have 2 methods of booting an OS from a USB Device.

method 1

1. Start computer, enter BIOS, (F2).
2. Set boot order for USB first boot.
3. Save changes (F10)
4. Shutdown computer.
5. Plug in USB with bootable OS
6. Restart computer.
7. BIOS finds and boots OS from USB.
Order is important.

method 2

1. Plug in USB with bootable OS
2. Enter BIOS (F2).
3. Navigate to Boot Override function.
4. Select USB device in the list.
5. Click on USB device.
6. BIOS automatically quits and boots from bootable USB drive.
Order is important.

In *this* 64 bit computer, neither of these methods works.
In this computer...

1.Plug In USB with bootable OS
2. Disable keys to make Secure Boot inactive.
3. Search for USB device in Boot Order screen and Boot Override screen.
If USB is not present, Reboot computer, enter BIOS (F2) now with Secure Boot disabled.
4 In BIOS, go to Boot Order screen, set USB device as first in the boot order (bios_boot_order.jpg).
6. Go to Boot Override screen, select the USB device and click (bios_boot_override.jpg).
7. BIOS blinks and returns same page, has not done anything and goes nowhere.
8 Leave USB plugged in, reboot computer, computer boots OS on HD, but not USB device.

I KNOW that the USB selection says 'UEFI : Imation_classic...'
I dont know if UEFI is simply a name attached to the USB bus, or a set function of the BIOS.
There is no toggle to change UEFI to OTHER or OFF other than Secure Boot, which people suggest enables/disables UEFI.
(I think I'm understanding that last part correctly).
It's been several hours, many days, lots of searching, reading.

Save this setup in the bios before going any deeper.
Secure boot needs to be already disabled when it boots.

Reboot computer and access bios setup.
Now change the boot device order so the USB is first.
Save bios setup.
Reboot.

Also see if you can access a boot device selection screen by pressing F8 or maybe F12 just as it boots.
This keeps from having to change boot device order in the bios.

If still having problems.
What bios is it?
What is computers make and model?

Secure boot is just a feature of the UEFI bios.
The other parts of the UEFI bios are still working.

Quote:
Secure Boot works like a security gate. Code with valid credentials gets through the gate and executes. However, Secure Boot blocks at the gate and rejects a code that has bad credentials, or no credential.

Most all Puppies do not have the needed credentials, so Puppy gets blocked if, secure boot is enabled.

Here is the bios details as requested.
Computer make/model is indicated in the name of this thread.

If someone later can communicate worked instructions for this bios, then I might try again.
Meantime, this laptop will stay on LM xfce, or MX linux.

I've just looked into this thread for the first time. It looks like a nightmare! WTF!!

In my laptop, Lenovo Ideapad 510, turning off secure boot is just one click. I've done it once, never turned it on again.

I always have legacy boot support turned on for booting Puppy from usb. I don't think I've managed uefi boot from usb even if the usb was prepared for it. My bios doesn't recognise the Puppy 'uefi' setup as such. But I do not try very hard. Uefi and secure boot are quite useless annoyances anyway, just needed to boot recent windows. I set usb up with grub4dos for legacy boot, the 'old way'.

Looking at the pictures of your bios, I notice that you have fast boot on and CSM off. Shouldn't it be the other way around.
Maybe this info from Barry is usefull: http://bkhome.org/linux/prepare-your-computer-for-booting-linux.html
