My UEFI behaves strange. For example:
I was in my PCs UEFI menu to show some settings to @fabby , but after this there are 2 new entries showing in efibootmgr. But i did not save anything in UEFI. I did try to boot some of the entries, went into the EFI-shell and then just exited it and booted Manjaro again with grub.
before:
efibootmgr [127]
BootCurrent: 0000
Timeout: 1 seconds
BootOrder: 0000,001A,0004,0020,001B,0021,0022,0003
Boot0000* manjaro
Boot0003* UEFI: Built-in EFI Shell
Boot0004* UEFI OS
Boot001A* UEFI OS
Boot001B* Hard Drive
Boot0020* UEFI OS
Boot0021* USB
Boot0022* UEFI: USB DISK 2.0 PMAP, Partition 1
I went into UEFI, and am back:
efibootmgr
BootCurrent: 0000
Timeout: 1 seconds
BootOrder: 0000,001A,0004,0020,0023,001B,0024,0021,0022,0003
Boot0000* manjaro
Boot0003* UEFI: Built-in EFI Shell
Boot0004* UEFI OS
Boot001A* UEFI OS
Boot001B* Hard Drive
Boot0020* UEFI OS
Boot0021* USB
Boot0022* UEFI: USB DISK 2.0 PMAP, Partition 1
Boot0023* UEFI OS
Boot0024* CD/DVD Drive
Do you notice ? now there are 2 lines added which where not there last time 
I give in, i do have a complicated setup on my machine. This is because i don’t often buy new hardware, but i do gradually upgrade part by part. Since some time i am afraid to change anything in the UEFI or boot-order because my UEFI does (for me) strange things. I do use Linux since more then 20 years, my actual Manjaro install is from 2017. Once i used lilo then grub, I had rEFInd, (but lost it) today I am with grub 2.06.
(Sorry for the spelling errors: not a native

fabby said to ask for @stephane 
I would like to:
- reinstall rEFInd (for safety)
- clean the entries in UEFI and keep only the necessary
This is not urgent, but it has to be done sometime from me (and yes i know - my pc - my responsibility)
I did reinstall rEFInd 10 minutes ago
