From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

You can leave on secure boot nowadays if you install and configure the sbctl package. It can use the Windows secure boot method, and you'll have a successful dual boot deployment.
Do I need to turn it off initially and re-enable it after?
I'm a little unsure of when secure boot becomes a problem
For a distribution like Fedora, it's usually not required to turn off secure boot. You'll know if it's needed when booting the install USB, as it'll give a "security policy" (or similar) warning.
Other things of note when dual booting are Windows "Fast Boot" and "Hibernation" features, which can put hardware in a state where it is unusable from Linux. Turning those off in Windows can fix things like your network interface not working. Windows also stores the time in a different way than Linux, if you are in a non-utc timezone, setting up NTP (automatically syncing date and time) on both Windows and Linux can help.
For me this didnt do anything. You need to reboot, and when the screen is black, force kill by pressing the power button. Lol Windows.
There also is a specific shutdown command with some parameters to force that. You can create a .bat file on your Desktop and use that to really shutdown your PC.
This is solid advice.
Only thing I would add is if you use a different OS that doesn't support secure boot during install, go ahead and disable it. After you install linux, then go through the sbctl setup, and it'll tell you when you should re-enable secure boot.
Thank you!
Thank you!
Thats what I thought. Secure boot normally needs a distro signed by damn Microsoft. This only applies for official Ubuntu spins and Fedora. Maybe some others. But the distro can create its own secureboot entry once running, and then you can enable it again.
Good to know
