I read an forum entry from nearly 6 years ago about am efibootmgr bug that
Doesn't let you change the boot order on a multi OS system if you have arch
linux as the default OS. Had some users report this as well in other
forums.
Now i am facing the that problem in my system with arch ubuntu and windows.
when i change the boot order , it shows the change 'temporarily' but when i
restart it boots the default (Arch linux Grub ) and the change disappears.
I faced this issue last month and gave up on it since I couldn't find any
detailed resource on this on the net.
This list may be my last hope.
If anybody could give some direction , would be much appreciated.

Hey,
It could be a motherboard problem. Sadly I've seen more motherboards
with weird bugs in their UEFI implementation than without. You could try
to change the boot order through the motherboard firmware interface
(often called "the BIOS" even if that isn't technically correct anymore)
and see if that helps.
Another thing that may have happened is that you installed grub as
portable bootloader. It will be called `efi/boot/bootx64.efi` on the EFI
system partition if that happened. A bootloader under that name is
auto-detected by the motherboard, even if you didn't add a boot entry
for it manually. Perhaps your motherboard always favors such bootloaders
over the normal boot entries.
If this is the case, you could install grub as non-portable bootloader
by not passing `--removable` to `grub-install`, and then delete
`efi/boot/bootx64.efi`. Alternatively, you might also be able to
configure your motherboard to prefer regular boot entries before running
`bootx64.efi` from that partition.
I hope this helps,
