Hi! I installed windows 10 some time ago and now i would like to uninstall/downgrade it to windows 8.1. How ever, my installation stops at 93% and it just says that the installation has failed. Nothing else. My computer is ASUS X73TK. I have created usb recovery drive and tried to install it but it just wont finish it. When i tried to install after doing the bios thing it would not let me install it anywhere. I am open to suggestions. Thank you in advance.
