I have a problem in grub or boot

Hi!

Instead of GNU appearing, its just running Manjaro. I mean no GNU interface. I reinstalled GNU from this instruction (GRUB/Restore the GRUB Bootloader - Manjaro )

sblk -o PATH,PTTYPE,PARTTYPE,FSTYPE,PARTTYPENAME

What did I do wrong?

Probably nothing (apart from the typo in your first command as posted here, which I guess isn’t the case with what you actually used!)

Could you post the output of cat /etc/default/grub please? That will show if the GRUB menu is hidden by default.

By the way, the “Generating grub configuration file” warning and error can be ignored.

This is assuming your Manjaro is booting normally apart from not showing the menu?

Really sorry for this history, but i just reinstall manjaro. Yes, manjaro normally started, but without grub menu.

Now all ok.

Just asking … did you run a system upgrade right after installing? This would likely have included a newer kernel and enabled GRUB menu visibility.
