I have a 16GB SD card with 10%FAT32 90%EXT4. I want to get a single disk image file that would contain all of the disc contents. How can I create a disk image of such a disc on Windows 10?

  • You cannot create an ISO image (colloquially: CD/DVD image) from an SD card, for obvious reasons. Perhaps, you should ask about your actual aim.

  • @DanielB Are you sure about that? Nov 3, 2016 at 15:50
  • @infamoustrey Yes. Though there is no difference in file structure (both are raw images), the term “ISO image” refers to an image of/for an optical disc. SD cards obviously aren’t optical media.

  • @DanielB Though the nomenclature might be correct, one could build an iso from any file structure could they not? Including that of an SD card? Nov 3, 2016 at 16:41

Linux dd.

dd if=/dev/sdX# of=/home/duckqueen/Desktop/usbimage.iso

    The question asks specifically about Win 10, so you might want to add a sentence about doing this with a Live DVD session on a Win 10 machine (including mounting a persistent drive).

  • Given that the card has an ext partition, and the asker knows as much, it can be taken that he/she/it has at least a glancing knowledge of Superior OS'. I thought stating all that would be redundant, and if they were going to pursue my answer a 40 second search would put them right. I don't know how or why "persistence" comes into it.

    It is unclear from the answer if /dev/sdX# means disk or partition... I mean if you'd wrote /dev/sdX it would be 100% that you meant disk, but why bother with additional #? From the context I think you meant disk...

You could use a tool like ImgBurn, it will read a usb to an iso and also write it back.


Perhaps you may find in the Control panel a tool "file history" there on the bottom left by "see also" go to "System Image Backup" and "create a system image" it should create an iso-file.

If you need a backup you could also use backup tools with gui for windows.

Or try the solution above with ImgBurn or CdBurnerXp.

E.g. Aomei this or Paragon this or Acronis.
