Dual boot with Ubuntu and windows suddenly stopped working

[kalpana]

Hi, I had installed Ubuntu 22.04 alongside windows 11 which was working fine for few months. After a system restart after power issues, the grub options don't show up. I am unable to boot ubuntu now.
Here is the boot repair url

The uefi secure boot is turned off and I have disabled fast startup on windows 11 now. Please help recover the Ubuntu installation. I have unbacked up android studio projects in it. Thanks

I went ahead with the recommended repair and it reported error NVram locked. Here is the new url
