Small note on the formatting.
format c: /q
The /q (that's "Quickformat"😉 will not work, unless the drive is already formatted. As it is not formatted after FDISK-ing it, you will simply have to format c: without the /q switch.
What /q does is in essence overwrite the file-information tables with 0's - it can't do that unless the drive is properly formatted beforehand.
