You have to disable both "fast startup" and "secure boot" in order to install linux.

(I installed Ubuntu 17.10 alongside Win10 few weeks ago on my UEFI laptop.)

I gave up on dual booting on a regular basis when Windows 10, once again, turned fast startup back on with a forced update. Now I use linux for everything at home.

Windows 10 is basically malware at this point.

I agree about the malware, I often make this analogy. I was in an exam today and people went to turn on their computers to write the test, we have two hours, and Windows decides to do an update. No asking, no options. These aren't power users; these people struggle with basic computing and are trying to get through school. So the administration worked with them so they could actually write the test but come on. You don't have control of your machine with Windows and I find that inappropriate.

Never once has this been true when I've pressed someone on it. It's FUD that's been repeated for years and oft reinvigorated by people that can't be bothered to Google or change a couple UEFI settings.

It's not even true in many (most?) cases that Secure Boot must be disabled.

> Also my laptop literally cannot have linux installed on it thanks to UEFI.

Does it have "secure boot" that can't be disabled/other keys added?
