Can't access Manjaro on boot

Good day. Earlier, I uninstalled Windows 11 by deleting its partition table and it worked. However, everytime I boot and enter boot manager via F12, I still see Windows 11 at the options. When I booted to kali linux, it said that Windows was booting at /dev/nvme0n1p2, which at first I found suspicious because that’s the boot partition that I set for Manjaro when I installed the OS. But I deleted it anyways. And now, I can’t boot to Manjaro. The Windows 11 option no longer show at boot manager, but so does Manjaro. I can still access the files though via PopOS, and none of it are corrupted. What should I do?

EDIT: Oh I forgot to add. I’m using PopOS now while I still can’t access Manjaro

I would use the Manjaro USB stick to boot into Manjaro and then reinstall Grub.

Nice idea. I’ll try doing that

This, basically, but a bit different, according to me.

I’d say:

  1. Boot into Manjaro live ISO environment.
  2. Open a terminal, and chroot into your installation:
manjaro-chroot -a
  1. Reinstall grub
pamac reinstall grub grub-theme-manjaro

There might be other steps in between that I’m not aware of. So be careful.

When done, exit the chroot environment and reboot to see if it worked.

exit
reboot

Also, see GRUB/Restore the GRUB Bootloader - Manjaro
