Thanks a lot! You safed me! I had an old Linux computer and got rid of the old hardware. I was able to create a virtual machine with your help. Thanks again.

Salut Marc,
D’abord, un grand merci pour tes instructions qui m’ont été très utiles.

Je viens de cloner sans aucun problème et via le réseau Fedora 27 (F27)

SOURCE: Dell Optiplex 790 (i3, 2ème génération, HDD)
CIBLE: HP Elitedesk, (i5, 4ème génération, SSD)

J’ai utilisé des clefs USB avec une Version Live de F27. Pour pouvoir me connecter d’une machine à l’autre via le réseau j’ai dû créer des mots de passe pour l’utilisateur root (SOURCE) et ajouter “-e ssh” dans la commande rsync ci-dessous :

# sur la machine SOURCE
# il n’y a par défaut pas de root password dans le système Live de Fedora
: su
: passwd

# sur la machine CIBLE (étant root et non pas liveuser !)
su
rsync -avHX -e ssh SOURCE_IP::all/mnt/slash/ /mnt/slash/

à la place de update-grub* il fallait utiliser
: grub-mkconfig -o /boot/grub/grub.cfg

* https://unix.stackexchange.com/questions/111889/how-do-i-update-grub-in-arch-linux

A ne pas oublier, il faut toujours être root et faire des BACKUP car si on se trompe …

Thank you very much!!! It worked like a charm in ubuntu studio 14.04.

Because i have /home and /var in two differents partitions in another drive, first to launch chroot command i had mounted these partitions
mount -t ext4 /dev/sdaX /mnt/slash/var #mount my /var partition type ext4
mount -t ext4 /dev/sdaX /mnt/slash/home #mount my /home partition
### and then
chroot /mnt/slash
### Install grub
grub-install /dev/sda
update-grub

Otherwise if i do not mount the /var partition when before chrooting, the command ‘update-grub’
fails.

Thanks a lot.

How to do this in a UEFI computer?

Thank you for the tutorial, really useful!
I just used it to clone a debian wheezy ( without X ) installation, and i had to do one step more to set up properly the system:
after the first boot of the cloned SO, i had ethernet and wifi cards named as eth1 and wlan1 instead of eth0 and wlan0.
That was because of the saved mac addresses in /etc/udev/rules.d/70-persistent-net.rules

so in had 2 lines about the source pc mac addr plus two lines with the cloned one:

SUBSYSTEM==”net”, ACTION==”add”, DRIVERS==”?*”, ATTR{address}==”OLDMACADDR”, ATTR{dev_id}==”0×0″, ATTR{type}==”1″, KERNEL==”eth*”, NAME=”eth0″
(same for wlan0)

SUBSYSTEM==”net”, ACTION==”add”, DRIVERS==”?*”, ATTR{address}==”NEWMACADDR”, ATTR{dev_id}==”0×0″, ATTR{type}==”1″, KERNEL==”eth*”, NAME=”eth1″
(same for wlan1)

i just had to remove the firs 2 lines, and change the seconds to eth0 and wlan0 .
hope it helps

thaks again

Andrea
