Windows can be added to each copy of Grub; there may or may not be a way to add other copies/types of Linux, I don't know, but it doesn't happen automatically
Usually you can. The tricky part is that I was effectively installing two copies of the same OS in parallel, which an automated installer can't really do in the same place without name/reference conflicts
The consensus of Ublue / Red Hat / OS installer / general OS development people here regarding a lot of things I have done was "nobody ever does that, I have no idea"
When I asked about the possibility or methods to install things certain ways, it was because my personal situation warranted the attempt and risk, but the response was not "there is a risk and we provide no warranty or guarantee of success"
The stance y'all adopted of being solidly and somewhat aggressively against same-drive dual booting under any and all circumstances instead of emphatically neutral and non-liable came 6-8 months later
I wonder if Cosmic will be an option for DE switching since it was designed separately from the ground up, in contrast with KDE which starts with Gnome templates and then butchers the config files
I do have a question. Is there any way I can make windows more like steamos? Such as making it so none of windows operations open and only the steam big picture mode does and then when ever you switch to desktop that's when it goes to windows?
So theoretically could I disable that and make steam os boot in big picture mode and then whenever I want to go to windows desktop I can set a "non steam game" as explorer.exe?
