Googling around for Hiren's Boot CD can't hurt either, as it can do. Said restore disk should allow you to access system restore, even if you're system absolutely won't boot anymore. One more thing, I do believe you can make a basic restore disk for just this sort of thing. If your smart enough to know what "Secure Booting" is, you'll probably be able to figure the rest out.

However, simply getting to the screen is probably the most compicated part. We’ve packed a ton of powerful features into one cleanup suite.

Avast Cleanup is an extremely effective bloatware removal tool and so much more. Please note that once you get into your UEFI settings, you're pretty much on your own, as there's no guarantee that your UEFI config screen will look anything like the one pictured. Remove bloatware, including unnecessary start-up programs and background processes, and watch your PC run just like new. This guide will use a tool called Bloatbox and run scripts using PowerShell. From there, it shouldn't be too difficult to disable Secure Booting altogether (and good riddance)! However, you'll still need to use UEFI without Secure Booting (as opposed to "legacy" BIOS settings), to run Windows 8. In this follow up video, I will show you how to remove bloatware from a windows 10 pc with an alternative tool. If not, assuming can make your system usable enought to dig deep into your Metro settings, you should be able to boot into your UEFI config screen. If you pay close attention, you just might (depending on your computer) find that you can enter into your UEFI settings during startup, see HERE.
