Unetbootin doesn't recognize ntfs format in Linux (Kali/Debian)

That worked for me. Format your USB as FAT32 in GParted Open UNetbootin and get it as far as the stage where it brings up the USB partition to install to e.g. /dev/sdb1 - Don't install the ISO, though Leaving UNetbootin open as is, reopen GParted Format the USB in GParted as NTFS If GParted doesn't automatically add the "boot" flag, add it yourself Now, go back to UNetbootin, which you've left open in the meantime, and click OK Doing so, UNetbootin will think you are using a FAT32 partition and will let you use NTFS format. EDIT: at this point UNetbootin complained the USB device was unmounted. Keeping UNetbootin open I ran sudo mount /dev/sdb1 /mnt. Then I hit "OK" on the still-open UNetbootin. It wrote the USB image to the USB.

The following works around the problem quite well for me. Maybe it just needs better documentation on the unetbootin man page?

For Example:

   unetbootin installtype=USB targetdrive=/dev/sdd1

  

   mount /dev/sdd1 /mnt
