Thank you for your answer, but no luck, I did not managed not to have the error. So I try a reinstall rebuilding the VLM completely, and the error did not go away. So, I reinstalled again, without LVM and then it was OK. I wont have time to check again for the solution to the error as I have to give back the machine. Too bad, because I did not learn from this one. Thank you again. Thierry -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?

Grrrrrub2 again!!
Hi, I did a new squeeze install on a desktop with dual boot, and install grub 2. System boot fine in debian, but $W was not present. No problem, I had this problem before and a simple update-grub solved it. But this time I got an error message: usr sbin grub-probe error cannot find a device for / (is /dev mounted) I am 'googling for about 10 hours now, but no luck. I purged and reinstall grub, still got the error, then performed a : grub-install /dev/sdb which went OK, but still update-grub gave the error. here is /boot/grub/device.map: (hd0) /dev/hda (hd1) /dev/sda (hd2) /dev/sdb hd0 must be the dvd drive, hd1 the HD with $W, hd2 the HD with squeeze on. It is split this way: dev/sb1 /boot dev/sdb1 a LVM df -k gives /dev/dm-0 / /dev/sdb1 /boot /dev/dm-5 /home /dev/dm-4 /tmp /dev/dm-1 /usr /dev/dm-2 /var Any tips, links welcome Thierry -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
