Sorry, you cannot do a clean install on this processor.
Read note 2 on this link:
Specifically: Intel Atom® Processors (code name Bay Trail) are supported for Windows® 10, 32-bit platform with the existing drivers that were delivered for Windows* 8.1.
You might try an upgrade from W8.1 32-bit to W10 32-bit. Then, use Windows to "Reset this PC", which should allow you to reset windows and allow you to remove all apps and data.
Whatever the case, backup your data before doing this.
