New Manjaro install (dual boot) gives "can't find UUID" error

@Wibol I guess you meant on the Live USB Manjaro

lsblk -f gives me

nvme0n1p1 vfat      FAT32            ESP              C2F3-279A

However the file opened by the command cat /etc/fstab has only one partition :

# <file system>           <dir>   <type>     <options>      <dump>  <pass>
/dev/mapper/root-image    /       auto       defaults       0       0

I think that is not what I’m supposed to get, because when I browse manually with Dolphin to the new partition created, the file I find in run/media/manjaro/b64993c0-(...)/etc/fstab/ is different :

# <file system>      <mount point>   <type>     <options>          <dump>  <pass>
UUID=C2F3-279A       /boot/efi       vfat       umask=0077         0       2
UUID=b64993c0-(...)  /               ext4       defaults,noatime   0       1

So I think that’s the file I you were talking about, and the UUIDs seem to be good, right ?


@stephane sudo manjaro-chroot -a returns

grub-probe: error: cannot find a GRUB drive for /dev/sda1. Check your device.map.
grub-probe: error: cannot find a GRUB drive for /dev/sda1. Check your device.map.

I assume that this device.map issue is also what makes cat /etc/fstab returns the wrong file…
