I’m trying to override the admin password on an old Dell optiplex 3090. It’s running windows 10.
Right now I’m unable to get it to boot to a USB drive. The boot options are
Windows boot manager
Onboard ipv4
Onboard ipv6
Under add boot options it’s blank. So there’s no way to add legacy option. I turned off secure boot. And the boot from USB option is enabled.
I have tried using several bootable USB drives with no luck. The weird thing is, when I added a efi/boot/bootx64.efi directory and file on the USB drive, it did show in the BIOS, but when I booted from it nothing happened.
I used Rufus to create the USB drive
