The short of it is that I was encountering this error: "Windows cannot be installed on this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only installed on GPT disks" and so after trying loads of things I figured I need to install using a disc but as I removed my optical drive and have it externally this won't be possible... I have heard mentioned that putting my SSD in a PC with an optical drive would then allow me to install it, bypassing the EFI issue. Would this work? I already have a 100GB NTFS partition ready. So in theory could pop in the SSD - just boot the windows install disk and install Windows onto the SSD? Does anyone know whether this would work and how I would go about it? Thanks in advance!
