I noticed that at every restart or start of the PC the number after the word Boot increases by one unit … I don’t understand why…

I hope the solution is not to go back to legacy and turn off uefi …
thank you for your support
P.S.: I tried to change the order with: sudo efibootmgr -o 0001, 0000, 2001, 2002
and to restart but nothing … still gives me the error indicated in the first post
