Yesterday i installed kernel 5.9, before which 5.8 was running. After that, when i rebooted, the pc got stuck at the logo screen. So, i assume that installing 5.9 has caused me this trouble. For now, i am only able to use my live manjaro via which i have also managed to get access to the grub menu. But what should i do now? Can something be done on the grub command line? Someone please save me… I want my old files back
are you dual booting alongside windows ?
if YES then check if windows is installed in uefi OR legacy bios
if manjaro is in uefi, [presuming its the only OS installed], did you allocate /boot/efi partition in fat32 fs of about 256 MB ? if you are dual booting with windows and windows is having efi partition as /dev/sda1, you should also allocate manjaro /boot/efi poiting to that same partition. update-grub means it should be listing the kernel to boot from along with other OS [if installed and os-prober is able to identify]
post output of efibootmgr -v ## chroot environment
so solution can be found easier than just presumption
