I dual booted my HP laptop with Ubuntu today and everything was working fine. Later I booted into Windows 11 and restarted the laptop and the grub no longer shows up. So I checked the UEFI boot order and only windows was in it. There was no Ubuntu. I tried reinstalling Ubuntu but the same issue came back. Then I ran boot repair from a live usb and it showed a locked NVram issue which I have no idea about. I have included boot-repair summary below.
