Got me a 2011 iMac where the previos owner installed Win10. Works great and until I dont do the upgrade to an SSD I use it as such. But sometimes I need to hook it up as external monitor. As far as I know this does not work with Windows. (Or does a Target Display Mode driver for Win exist?)
So I want to install MacOS (High Sierra I think) but in a manner that Win10 remains and is still bootable.
Any instructions?
