Il me semble oui, mais faudrait demander à Bencello je crois qu'il s'y connait pas mal sur le sujet.

rhoo, trouvé en 2 sec sur google bon daccors en anglais mais bon :
And the answer, since this post was the closest i got…
open “disk utility” (from applications | utilities)
click “scan image for restore” (from the images menu)
select your dmg file. wait.
click “restore” at the top of the main window
drag the image (the disk icon under the dmg file at the bottom of the left hand pane) to the “source” field, and your disk (the icon for your firewire disk or whatever, at the top of the left hand pane) to the “destination” field.
wait again.
restart the computer. hold down the “alt” key. the drive should appear along with your normal hard drive as a startup disk.
WARNING: most macs can’t boot from a usb disk - many can boot from firewire and scsi, all can boot from an internal drive or a cd/dvd.
that’s what i learnt today… thanks for the pointer gwhiz.
