Please add a prominent warning advising users to be consistent in their usage of UEFI or CSM (BIOS) style installation when booting multiple operating systems. Whether by misconception, firmware quirks, poor media creation tools, or accident, users have been consistently reporting issues with booting their Windows installations after installing Fedora. I have observed that a significant number of these issues relate to the user "disabling UEFI" to install Fedora, then discovering that their UEFI installation of Windows no longer boots. Browse through ask.fedoraproject.org for Windows related questions, and you'll see how prevalent these issues are.
There is documentation under development to further explain the issues involved, but it would be hugely beneficial to have a simple warning to be consistent displayed when the Fedora image is downloaded. Maybe in download-splash?
Totally agree with immanetize. The issue actually occurred to me once. I had to wipe the disk and restart from scratch.
The download-splash would be the logical place to put a warning; but it doesn't seem like a place it would fit in. We can put it under the link, but it would look a bit awkward. We could also place a link to "please read me" under the download link.
What do you think? We could have a question saying "are you using an UEFI system? (are you dual-booting with Windows 8.x?)", then use jQuery to slide down a notice about being consistent with BIOS/UEFI.
I may be wrong, but isn't that a topic which should go under an Installation Guide? We don't have the Installation Guide on the websites, but we have a link, for example, to [http://docs.fedoraproject.org/en-US/Fedora/20/html/Installation_Guide/Making_USB_Media.html To install Fedora using a USB stick, follow these instructions].
IMO we provide the images and tell people what to do with them, but not how to install them on different machines, with specific configurations or other Operating Systems. These should be topics to put in the Installation Guide (and we link to it too).
People rarely read the installation guide, though. I personally think this should be put as a splash in Anaconda.
This is definitely a topic that should be addressed in the Installation Guide, and we are drafting a Multiboot Guide as well. Both of these will give detail and context. When the multiboot-guide is published, it might even be a good idea to link to it from the website as well - but that's for another day.
For the Website, a very simple admonition should be sufficient. What about a bubble with something like:
"For best results using Fedora with other operating systems, be consistent. Do not disable UEFI to install Fedora if your computer is preinstalled with an operating system that uses UEFI.
Robert and I talked about this on IRC; I'm going to write an article for docs.fp.o that can be linked from the website.
Could you give us an update for this task?
https://docs.fedoraproject.org/en-US/Fedora/22/html/Multiboot_Guide/BOOT-BIOS_or_UEFI.html might cover the relevant points. I'll probably have it updated for F23 by GA.
Wow I totally missed this. I think it's all fine now, if we can do anything feel free to reopen it on pagure.
