How to create a diskimage of an SD card with partitions having different filesystems?

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. – Daniel B – 2016-10-31T19:24:22.240

@DanielB Are you sure about that? – infamoustrey – 2016-11-03T15:50:21.430

@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. – Daniel B – 2016-11-03T16:02:04.003

@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? – infamoustrey – 2016-11-03T16:41:33.800

@infamoustrey: Yes, if you see it like that, it's certainly possible. My impression was that the OP wanted a disk image (which he called ISO image) straight from the SD card. Unfortunately, no clarification was given. – Daniel B – 2016-11-03T17:01:38.893

1The 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). – fixer1234 – 2016-10-31T18:05:50.697

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. – user657451 – 2016-11-01T04:59:30.657

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... – 71GA – 2017-09-10T09:53:16.143

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.
