My purpose is to save/restore Clonezilla images to/from 16 GB drive.
Because images are weighty, I needed something else than FAT(32).
My choice was NTFS so I could access images from Windows machines without additional difficulties.So here I am, trying to write Clonezilla image to an NTFS USB-drive, and I fail on both Windows and Ubuntu, for example RUFUS says that Clonezilla's image is incompatible with NTFS partition type and suggests FAT32, and Unetbootin just won't list a mounted USB drive which is in NTFS as a usable (to write on).
So I used mkusb which is a nice GUI above dd command.
The result was a blank (unpartitioned) space and a 3 MB partition.Even though the space is "unpartitoned" (see selected line on picture) 
the USB drive is still bootable (no idea why dd'ing an .iso has such an effect)
So I created a 15 GB NTFS partition on the leftovers of USB and successfully stored some Windows's partition image to this freshly made part of USB drive.
Now, when I try mounting the NTFS part of USB drive as /home/partimag (default source directory for image saving/restoring), it asks for force mount in GUI (which has no effect), and honestly tells that "Resource sdb is busy" in console.
However all the same works if Clonezilla is booted from a separate USB/CD
My questions:First. Is it even possible to make Clonezilla boot AND restore images from same USB drive?Second: Are my problems related to the fact I'm using a not-so-good dd method (I feel like sdb becomes fully busy because that bootable 200MB part with Clonezilla in the beginning of drive isn't recognized as a partition which just makes mount lock ALL the USB drive partitions)? Or I missed something else?
P.S. this may be a stupid question, but is there a way to dd the 200mb Clonezilla image to only sdb1? I mean, maybe that would make Clonezilla normally mount the NTFS part of USB drive?
