FWIW, I’ve put some effort into explaining how a dual boot of Windows 10 and Fedora Atomic (read Silverblue/Kinoite/Sericea etc) can be achieved. While it’s far from exhaustive, it should be fine as long as your specific installation of Fedora Atomic doesn’t require special attention (which happens sometimes with owners of an Nvidia GPU*). After Fedora Atomic is successfully installed, proceed with following the instructions found on the following parts of uBlue’s documentation: here, here and finally pick whichever uBlue image you’d like to install from this list; specific instructions are found directly underneath the text boxes for each individual image, but ensure you’re installing the one with the correct Fedora version (37/38/39/stable/latest etc (which are accessed via tabs)). If you can’t decide on which version you’d like to install, then just go for 39.
