[SOLVED] Manjaro new installation Black screen - no boot no grub

Maybe grub configuration file hasn’t been created automatically. Chroot again and execute this:

sudo grub-mkconfig -o /boot/grub/grub.cfg

I did that too. Still no success.

Why did you update system using usb? Was manjaro not booting after the fresh install?

yep exactly. It wasn’t booting at all after new install. I thought if I update it will be fixed. So I chrooted to do that. Still didnt work.

Then if I am right, you installed bootloader in the USB drive rather than your own hard risk. Completely remove grub from your system first, including the folders in /boot/grub. Then install again and update grub. Besides provide me the output of sudo update-grub.

here’s the output

/dev/sdb1

Is manjaro installed in sdb? If not then grub is not properly installed. If not sure, execute this:
lsblk

i don’tknow how things changed here. When i restarted my computer USB became /dev/sda. But I had installed manjaro in /dev/sda.

Now it seems Manjaro is in /dev/sdb

I would recommend a fresh install at this point. You can recover from the problem but this has changed your partition scheme name. When in manjaro installer in partition section there is a bootloader option. Select hard drive and this will be solved.

Just restarted computer and the scheme is back to sda1. So weird.
Also i reinstalled twice using hardrive as bootloader.

dev/sda1

sudo pacman-mirrors -g

sudo update-grub

Then check where your partition is by

findmnt /

Remember, this is on actual OS, not on livecd.

hi everyone, zenleaf:grinning:

have you tried to reinstall the Manjaro to your USB drive? … bcoz that same problem happened to me when i tried to install the Manjaro.

it turned out that i didnt install Manjaro correctly with the RUFUS (iso to usb drive) on my Win10, before i reinstall the Manjaro system to specific partitions. i plugged out the USB while probably some files werent copied well.

good luck. :slight_smile::thumbsup:

So good news! I solved the issue :slight_smile:

Definitely a partitioning issue. I used the live installer and manually partitioned the disk into /boot and /swap and /
after which everything worked.

When I installed all previous times I used the erase disk option in the live installer which seemed to cause the problem.

Thanks for assisting me was really helpful. Owe you guys each a coffee/beer :wink:
