Créer une image ISO
From CD/DVD/HDD :
$ dd if=/dev/sr0 of=~/Image.iso bs=1M conv=noerror status=progress (1) (2) (3) (4)| 1 | /dev/sr0 for CD/DVD /dev/hdXX for storages |
| 2 | bs=1M : buffer size 1 Mo instead of 512 octets (speed up transfert reducing beacons), more info here : dd buffer size |
| 3 | conv=noerror : continue over Input/Output errors |
| 4 | status=progress : to follow the operation (only errors and summary are shown by default) |
From files and folders :
$ genisoimage -udf -allow-limited-size -r -J -V "ISO Title" -o /foo/barGet it back to a bootable USB stick :
$ sudo dd if=~/Debian.iso of=/dev/sdb bs=1M status=progress; sync (1)| 1 | sync to wait until the image is entirely copied on the USB key |
Or even simpler :
$ sudo cp ~/Debian.iso /dev/sdb ; sync (1)| 1 | sync to wait until the image is entirely copied on the USB key |
