Anyway, I already told you to post a photo of it. Unfortunately you ignored it several times. This will have been the last time I asked.
I have no idea how to post a photograph on this forum.
Will the following help?
====

Note the two '>'s in front of the Boot Order entries.
On the actual screen, these are little blue triangles.
I can change the order of the lines, (and see the changes back after reboot etc),
but I can't remove or move these >'s in front of the two lines indicated.
If I move the lines up, the perps move with them.
Also, I can't disable the UEFI order, and the help-text explicitly says the UEFI order will take precedence over the Lecagy Boot Order.
Disabling indiviual options is also not possible.
