Now my computer is all messed up. I can't install, uninstall, can't open some buttons when asked to select, can't download. It's awful. I really think my installer has been deleted. Is it possible to reinstall Windows 8 over the 8.1
Save whatever important data that is on the c: Drive. You will need to perform a re-install of Win 8 which means all data on the c: Drive will be deleted.
