I have a 2010 iMac and had Mac OS High Sierra and Windows 10 having installed Windows 10 via BootCamp. I then made 3 new partitions using Disk utility and installed Ubuntu 16.04 using these partitions as EFI, root and swap. I did not touch the Bootcamp partition which is still present. Refind on the ALT menu still find Windows, but when I try to boot it I get a "Missing Operating System" message in plain white text on a black background. I have tried using a Windows install DVD to repair startup without success and also tried to re-install Windows but I get a "Too many partitions" message from the installer. Is there anything I can do make Windows boot again on this machine without losing Ubuntu? Can I edit the MBR from Ubuntu or Mac to get Windows booting again?
