Hello and welcome to the forum.

But you still have access to live session, right? That error would be good to know, so maybe you can share it here.
A good read about Installation Guides - Manjaro with the steps you have to take.

Yes, i just wrote the error by hand.

External command finished with errors.

Command mkinitcpio finished with exit code 1.
