How?

Just change the “boot mode” back to what it was.

I did this in bios.

You may need to run grub-install again.

(or use the install-grub script)

First you probably need to gain functionality … such as by using live media (like a USB).

In fact theres an arch forum thread from yesterday with the same symptoms…

(though note your path may be different, such as /boot/efi)

PS.

Appears to be a product of ‘efi losing its linux record for some reason’.

I can only go with what you tell here.

If you changed something - and then changed it back to what it was - there should be no reason for you to ask about a change, because there effectively was none.

When I boot to live Manjaro ISO and press detect efi bootloader I have 2 options

(hd1,gpt1)/efi/Manjaro/grubx64.exi
(hd1,gpt1)/efi/boot/bootx64.efi

It’s seem I booted a windows10 usb flash drive by mistake. Can I delete the second one. Thank you.

In the live media I booted here.

PS.

Just Reinstall and Update Grub seems to solve the issue.
Thanks again.
