I've got a laptop here that came with a Windows 8 installation. What I did: Removed the harddisk, put in an SSD, and now I've (unsuccessfully) tried to install Debian. I've used all the default options of the Graphical Installer and chose not to force UEFI. However, it doesn't boot, but hangs in PXE trying to start via IPV4.
Now, I'm revisiting the installer and wondering: If I choose "force UEFI", does that only affect the installation on the SSD?
Can I swap back the harddisk and will my Windows 8 installation automagically work, or will "force UEFI" do other things I don't know about that will make it impossible to swap back my harddisk at a later time?
