I turned on my computer and saw the pc was taking a bit more time then usual to boot up. And after a long like 1min of trouble it directly booted into windows. I had no idea what’s going on bcuz it was expected to show the grub menu. Then i checked the UEFI menu and woah! my manjaro bootloader is gone. So, I rebooted into windows and checked the partitions but it seemed like theres no issue with the partitions. And as of my brother he didn’t have updated Windows (cuz he uses win11 and i use manjaro). So i dont really know why this happened.
How could i regenerate the bootloader?
