Windows 10 so uname does not work there
Rawrite32.exe MAY overwrite a Windows 10 (ver 1607) partition on the second usage if no target (DVD or USB) exists on the host. In my case I lost a hibernation partition which was easily recovered. My system is an Intel NUC D54250WYKH with a 256G main SSD and a 30G hibernation SSD. I was using rawrite32 to create a Fedora 25 iso.
0. Take steps to allow recovery of your Windows 10 machine.
1. Download rawrite32.exe, Windows version.
2. Plug in a USB drive and run rawrite32 to write an image to it.
3. Eject the USB drive.
4. Exit rawrite32.exe.
5. Start rawrite32.exe WITHOUT and USB drive (or any DVD), i.e., there is 'nowhere' for an iso to be written. Rawrite32.exe seems to 'remember' the USB from the previous use.
6. Write an iso.
7. Recover your Windows 10 if necessary.
Not fix. Mitigation is to ensure that a USB drive is plugged in before writing.

This could be a Windows issue.
