Windows update bug... Can't install updates/Windows 10! Please help me.

So, yesterday i got the "Your windows 10 is ready for install" or something from the icon on the task bar. I then downloaded the updates in winodws update and it said that it was done downloading the updates and i needed to restart in order to start installing windows 10.. I then restarted and nothing happend.. I then went in to Windows update and saw that it said that winodws 10 update failed to download, I then tryed to reinstall the update but when i removed the update the "restart your computer to install your updates " in Winodws Update kept being there so now I cant search for updates or update anything in Windows Update... It just says when I open windows update that i need to restart..

Please help me.... I would REALLY appreciate it!
