Manjaro without grub?!

I want to install Manjaro for the first time, I have now installed Linux Mint, I had 2 other distributions installed some time ago.
At “manjaro-xfce-21.2.0-211220-linux515,64 bit” the first page opens with no such device,unknom filesystem,grub device.I don’t know what to do.

Can you post

  1. fdisk -l
  2. blkid ?

You need to use Manjaro’s grub to boot Manjaro.

Somehow, I highly doubt this.
