Windows+Manjaro dual installation - Grub boot to black screen

Until not long ago my dual Windows+Manjaro installation worked fine.
Since yesterday Windows boot fine from Grub but Manjaro boots to black screen from Grub.

I tried, based on these instructions i found in one of the internet sites, to reboot manually but it failed:

grub> set root=(hdX,X)
grub> linux /boot/vmlinuz-XXXXXXXXX root=/dev/sdXX
grub> initrd /boot/initrd.XXXXXXXXXXX
grub> boot

The error message i got was:

> בלוק ציטוט
mount: /new_root: no filesystem type specified

(i tried to add images or links but the this forum won’t allow)

Since i have very low understanding in Linux and cases like these i would like to see if someone can offer easy solution.
I have already created Live USB and i read something about chroot command but i’m not sure i understand everything.

That kernel is EOL … switch to 5.4 or 5.8
Have you checked this?

Not sure how i should check it?
All i have installed is Linux 5.8.

I guess this is the kernel of the live ISO… :wink:

Then is an old ISO … :wink:

regardless … chroot your system and try to fix it so you can boot it.

I’ll try read and understand what was offered before.
[How To] Save your Manjaro installation when it breaks.

I managed to get into my Manjaro installation through typing:
manjaro-chroot -a
From Live USB.
I also used a command to update grub and all other packages:
sudo pacman -Syyu

But still when i exit Live USB and load Manjaro without Live USB, Grub still doesn’t boot Manjaro.

Something is missing.
Help will be appreciated

You could try to restore the bootloader as described here:
https://wiki.manjaro.org/index.php?title=GRUB/Restore_the_GRUB_Bootloader

If you have any question in detail, just let us know.

I would like to…but it contains alot of technical data that i’m not familiar with.
I’ll try to see what i can do…but i’m not hopeful.

Maybe this can help - i typed this command and this is the output i got:
