To debug this, I would like to see the results from:
- from your existing system, run 'efibootmgr -v' and paste the output.
- boot to the installer
- from a terminal, run 'efibootmgr -v' and paste the output.
- remove the USB stick.
- reboot.
- if your boot options come up, reboot again until you reproduce the bug.
- insert the USB stick and reboot.
- if at all possible, boot the USB stick without adding the stick to the firmware's boot options. I.e., if the grub on the USB stick comes up automatically, boot it; if you have an option to boot from a file *without* doing 'add boot option', do that.
- once booted, get the output of 'efibootmgr -v' again.
