How to dual boot Windows 10 and (Kali) Linux?
I solved this issue following these steps;
-load into the Live environment of Kali, -start up the Applications->Systemtools->Administration->GParted partitioning tool from the menu
ignore the error about the gpt: this is probably why you have this problem in the first place..
-remove all partitions, then, in the menu 'Device' choose ' Create partition table and create an MS-DOS partition table.
-Create the appropriate linux partitions at the end of the disk: make sure you keep enough room at the start of the disk for the windows install.
If you're not sure about the partitions, here's good reading: http://www.howtogeek.com/howto/35676/how-to-choose-a-partition-scheme-for-your-linux-pc/
Now apply the changes in Gparted, reboot the machine into the Windows10 installation -media. Setup Windows in the free space, after that, boot into the kali -setup
Kali will now recognize the windows installation as a vista install..
You should be able to follow the setup wizard from there.
