It's output will be used to detect bootable binaries on them and create new boot entries.

Adding boot menu entry for UEFI Firmware Settings ...
First: Backup any valuable data.
Hope, my second solution works, as one of the last postings tells “solved”.
The parts for Manjaro linux should be in /boot/grub/grub.cfg
Chainloading of ONE system is required AFAIK.
(One system is the Big Boss - the other the humble slave)
and so on…
the /boot/efi/ of manjaro must be used - finaly even Windoofs uses this location
if started from Manjaro by chainloading (that is the normal way).
Do not format existing /boot/efi/ partition - “use” is the correct thing… nvme0n1p8 is your master.
Thanks.2nd option of automatic partition worked.
ON BIOS UEFI menu i can see fedora entry along side manjaro. By changing boot order i can boot in to fedora.
But manjaro grub menu still not displaying fedora entry don’t know why.
And but from fedora grub menu i can see manjaro , windows . But manjaro is not booting from fedora stuck on black screen.
Anyway i just want to boot and test os on small partition. not using this for regular usage
