Hi! Thanks in advance for your help. Basically, I use a fairly old MacBook, who's screen no longer functions at all. I therefore currently use an external monitor as my primary display, and keep the lid of my Mac closed. However, I would like to create a Windows partition on my MacBook, an I think that when you try and boot up from another partition on your hard disk, the Mac automatically uses the MacBook display rather than the external one. Is there any possibility to make the Mac think that the external display IS the primary, laptop screen, so that the laptop screen is no longer used? Thanks!
