I’m running on a system with dual boot with Windows 10. I can boot to windows 10 thru GRUB menu well. But it doesn’t boot when Manjaro is selected. This happened right after I updated. Prior to this, I have correct NVIDIA driver installation. What should i do?
Welcome to the forum! 
I would recommend booting up from the Manjaro install medium in live mode ─ any one of the install media will do ─ and issue the following commands in a terminal window… 
ls -l /boot/efi
ls -l /boot
Click the </> button in the toolbar of the post editor and paste the output of those two commands in between the two lines of backticks (```).

What’s exactly happening?
In addition to @Aragorn’s suggestion please enter
sudo manjaro-chroot -a
inxi -Fazy
parted -l
efibootmgr -v
Post the result here.
Then don’t forget:
exit

Thanks for the prompt help! Here’s the output

Try to reinstall the initramfs by
sudo mkinitcpio -P
when chrooted.

It just shows the logo of my motherboard and freezes. This is the output.

It’s a litle bug…
But more important: your initramfs is missing, see command above or follow @Aragorn’s set of commands.

Okay, I see the problem already: you don’t have an initramfs. Okay, here’s what to do…
Assuming that you’re still booted up in the live session, issue the following command in the terminal…
su -
Enter the live session’s root password. Now proceed with the following commands…
manjaro-chroot -a
mkinitcpio -g -k /boot/vmlinuz-5.8-x86_64
sync
exit

Try 'readlink --help' for more information.

@Wollie, should i proceed with sudo mkinitcpio -P
Hmm… If the -k option is no longer supported, then they haven’t updated the man page. 
Well, try the following then instead…
mkinitcpio -P -g
I’ve executed the commands, and got the confirmation that the image was generated successfully. The problem still persists though after reboot 
The question is how the initramfs file got lost? Have you interrupted the update process?
In that case chroot again and apply
rm -f /var/lib/pacman/sync/*
rm /var/lib/pacman/db.lck
pacman-mirrors -f && pacman -Syyu
and report what you got.

I would afterwards install the proprietary Nvida driver. When in chroot enter:
mhwd -a pci nonfree 0300
Also check if you have fully shutdown Windoze. If not, start Windoze and switch off fast boot. This could set the drive in a hibernating state affecting updates on manjaro’s site.
Hmmm. I think this might be a relevant info. Prior to updating Manjaro, I rolled back to a previous version of cuda and cudnn (v7.6 and v10.1 respectively) because of compatibility issues with tensorflow with the latest cuda and cudnn versions
Btw, here’s the output of mhwd -a pci nonfree 0300

P.S.
Yep. I have fast boot switched off. I’ve done this before already since it was affecting network connections whenever I boot to Manjaro before.
Remove cuda first. if you need this tool then you can install it afterwards.
In chroot:
pacman -Rsn cuda
on @Aragorn, this is not something new and can be fixed. The repo’s have been updated. We start to remove whatever is given behind required by as long as it’s not getting some system relevant. So, some steps might be needed.
