with the sda partition has btrfs file system
I did:
sudo grub-install --recheck /dev/sda
but i got this error:
Auto-detection of a filesystem of /dev/sda1 failed.
Try with --recheck.
If the problem persists please report this together with the output of "/usr/sbin/grub-probe --device-map="/boot/grub/device.map" --target=fs -v /boot/grub" to <email address hidden>

executing the following command line
/usr/sbin/grub-probe --device-map="/boot/grub/device.map" --target=fs -v /boot/grub

i got the error:
/usr/sbin/grub-probe : info : impossible d'ouvrir `/boot/grub/device.map'.
/usr/sbin/grub-probe : erreur : cannot find a GRUB drive for /dev/sda1. Check your device.map.
