As soon as you mentioned the difference in screen resolution, the first thing that came to mind was that the Surface Pro 3 sounded like it was booting into BIOS / Legacy Mode rather than UEFI. But this link says that it uses UEFI. However, the Surface Pro 4 uses a different type of UEFI. Maybe that has something to do with it? https://www.microsoft.com/surface/en-us/support/warranty-service-and-recovery/how-to-use-the-bios-uefi?os=windows-10 On Saturday, March 26, 2016, Christian Nilsson <nik...@gmail.com <javascript:_e(%7B%7D,'cvml','nik...@gmail.com');>> wrote: > Hi Andres, > > On Tue, Mar 22, 2016 at 5:25 PM, Andres, Roman <roman.and...@netree.ch> > wrote: > > Hi! > > > > > > > > I have a question regarding wimboot.
