Excellent. Being able to install a fresh OS at will is one of the many fun things in Linux. Theming is another. I would advise you do a backup of anything important on Windows and just erase the entire disk and do a clean install of Linux. If you still need Windows, install Virtualbox and install Windows as a VM. Best of both worlds. I do this to enable me to print to my Canon printer because the Linux drivers don’t work ,it needs Windows to print, calibrate etc.
