Can't upgrade to latest build

[ULOP3Z]

Hello I've been trying to update to the latest build for some time now, I'm currently on 9926. The update downloads fine and it also goes through the process of installation fine, up until it's time to restart the computer for the final step, that's where the problem begins. It gets stuck on a boot up loop, it loads to the windows logo and says preparing automatic repair and restarts the computer again and again with the "preparing automatic repair" message please help. I made an installation disc for 9926 so that's how I'm able to reset the computer but I've also made one for the latest build but I still get the same boot up loop problem. If anyone has a solution to this please help, I really want to be on the latest build and I'm worried that I won't even be able to install the official release

If you already try to install through an ISO of the last build, I suggests you make a clean installation.
