UPDATE: This is for a Mac Pro (Mid-2010) MacPro5,1 with the latest firmware, 6-core 3.46 Intel Xeon, 32GB 1333 Mhz DDR3 memory.
I tried the instructions on this post: Triple Boot: “Missing operating system” on Windows 7 partition after Ubuntu installation on my Mac Pro and I’m getting the following at the end of the gdisk commands:
Warning! Main partition table overlaps the first partition by 26 blocks! Try reducing the partition table size by 104 entries. (Use the ‘s’ item on teh experts’ menu.) Aborting write of teh new partition table.
Any suggestions?
I was able to boot into Windows 10 just fine a few weeks ago. I’m not sure what happened in the interim. The only fixpacks I’ve done were on the Windows 10 side. Nothing on the Mac (High Sierra) side.
The Windows disk is a 1 TB SSD with 320GB used for Windows 10 and the other 680GB used for an Apple HFS+ disk.

. Some of these command may require SIP to be disabled. What is the model/year of your Mac? Do you know if Windows is installed to BIOS or EFI boot?
