I would like to create a disk image of a dual boot system (Ubuntu, Windows 11). Ubuntu is on /dev/sda1 and Windows 11 on /dev/sdb1

How can I accomplish the task with the dd command? I tried sudo dd if=/dev/sda if=/dev/sdb of=dualboot.img bs=64K conv=noerror,sync. However after two seconds the clone option stops leaving behind a image size of 4096 bytes.

    dd does not support multiple if=. You shouldn't use noerror,sync either. Since you have two separate drives, why not backup them separately? Commented Mar 23, 2024 at 18:32

    You should not use dd as a backup tool. It also copies empty space, so both takes a lot longer & makes larger files. Use Windows tools for Windows. I prefer not to back up Ubuntu system (root), but use rsync to backup /home, some settings in / and list of installed apps to make it easy to restore. And I do that to multiple drives at different times. discussion of alternatives/strategy backups ubuntuforums.org/showthread.php?t=2465713 & help.ubuntu.com/community/BackupYourSystem Commented Mar 23, 2024 at 18:42
  • I would use Clonezilla for that task. Commented Mar 23, 2024 at 19:09
