What ever you do back up that eSupport folder to another location.
Sounds like your beyond recovery so Clean install is your best way out. but have that eSupport folder ready to install drivers as you'll need it just about as soon as you get windows installed and running.
Once you get it running again get Macrium Reflect Free and create Images, next time you run into issues you just restore the most recient image before the issues started. It will save you from any windows issues in about 10 to 20 minutes
