thanks for the reply, I am able to change the boot order from the BIOS menu. It works A-okay from there, I am trying to accomplish that with efibootmgr.
could you cite any link where I could read about it in details ? where the bootx64.efi file will be stored if I install it in NOT IN PORTABLE mode(?)? cuz that would help me know whether the grub is installed in portable or none portable mode.
Also, would be nice if you could provide any source where I can read about how I make my motherboard detect regular boot entries (instead of the /Efi/boot/bootx64.efi)
thanks,
As far as I am aware of, /Efi/boot/bootx64.efi is mandated by the efi spec. It could be that there is a 2nd location for the bootx64.efi file. Or that the 2nd location is mandated by the spec. I guess searching the internet for bootx64.efi will show more decesive information. And the archwiki, too. -- u34

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,
