Issue with grub-mkconfig in a raw image

[Stéphane Hoc]

Hello,

I'm trying to install and configure GRUB with chroot in a raw image and I don't 
know what is wrong:

grub-mkconfig -o /boot/grub/grub.cfg
Generating grub configuration file ...
/usr/sbin/grub-probe: error: failed to get canonical path of `/mnt/image.raw'.
No path or device is specified.
Usage: grub-probe [OPTION...] [OPTION]... [PATH|DEVICE]
Try 'grub-probe --help' or 'grub-probe --usage' for more information.

Regards,

S.H.
