I installed linux-manjaro-xanmod-cacule-uksm from aur . I rebooted my system and was greeted with a blank screen with lasted forever.even my grub boot-loader did not appear.Hence i booted into a live disk ch-rooted into manjaro and tried to reinstall grub.It failed(i did not note down the error message). I also had kubuntu installed in my hard disk, hence i ch-rooted into kubuntu and tried to update grub.It was successful.I rebooted chose the option manjaro(on /dev/sda3) from grub menu.it did not boot.Then i tried selecting the option “advanced options for manjaro Linux” from grub menu and selected the “Manjaro Linux (Kernel: 5.11.2-1-MANJARO x64 - fallback initramfs5.11.2-1)” option.it worked(booted successfully).I tried all other options(xanmod , xanmod fallback initramfs,official kernel) only fallback initramfs of the official kernel(5.11.2-1) worked.i uninstalled xanmod and kernel 5.11 using pamac gui and manjaro kernel manager respectively.then installed the official kernel 5.9 from manjaro kernel manager.but still i am facing the same issue only " Manjaro Linux (Kernel: 5.9.16-1-MANJARO x64 - fallback initramfs)" option from grub menu boots.
sudo mkinitcpio -P
did not help.
Here’s some information about my pc
