I'm booting from a Windows 8.1 DVD I made from the ISO on Microsoft's site. I can manage to start the installation to the HDD but at some point it reboots and begins the next phase. However, my monitor displays "Video mode not supported" and I can't see anything to continue the install! It's a pretty old monitor - an ADi 4:3 thing with a native res of 1280x1024. According to the official specs you only need a display capable of 1024x768. Any ideas folks?
