Cannot Boot to USB on Dell Desktop

[chunter]

Computer: Dell optiplex 3090
Operating System: windows 10

I’m trying to boot to a USB drive but I don’t see the option on my Dell optiplex 3090. I turned off secure boot, enable boot from usb is on. I have tried creating several different bootable usb drives on several different usb sticks. The only boot options I see are :
Windows Boot Manager
Onboard IPv4
OnboardIPv6

Under the add boot options, its blank, there’s no legacy boot option. One weird thing is, on my bootable USB drive, when I add a efi/boot/bootx64.efi directory and file, it will show up on the bios as a bootable drive, but when i select it, it doesn’t work.

What are you trying from the usb windows, Linux etc.
Are you using a version 2.0 or 1.0 as the boot usb

[PeterOz]

The only boot options I see are :

Is this from the F12 boot menu?

I’m running pcunlocker enterprise edition on the USB. I created it using Rufus and the pcunlocker enterprise edition iso

[chunter]

Is this from the F12 boot menu?

Correct. F12 takes me to BIOS UEFI boot options and
Other options:
BIOS setup
BIOS flash update
Etc

The only option under uefi boot is
Windows boot manager
Onboard nic ipv4
Onboard nic ipv6

Here is f12 and the BIOS setup

[PeterOz]

If you plug in the usb first, then power on and in bios add boot option.

I’ve tried different USB sticks in different slots plugged in before I turned it on but it still doesn’t show up. Ultimately, I’m trying to overwrite the old admin password. I’ve used Rufus and iso2disc to make the USB. I’ve used both mbr and gpt

[PeterOz]

the old admin password

Do you know the old password?

Do you know the old password?

No.

Should this be closed?

Until @veeg or jmarket determine if Rule #13 applies here, I ask if you have tried that bootable USB stick in another PC to see if indeed it has been made bootable and is detected as such in another PC.

No good blaming the Dell just yet if it turns out the stick isn’t what you think.

[jmarket]

For now, this is not a violation of rule #13 but will be amended to include passwords.

This thread can remain open

No. We got some old computers from work that they were giving away and I’m going to use them as media servers. But these PCs were never reformatted

USB Configuration Allows you to enable or disable the integrated USB controller for:
● Enable USB Boot Support
● Enable Front USB Ports

You may have to save and exit.
Go back to bios
can you now see boot from usb and enable
