In order to create an appropriate Windows 10 partition on a Mac with High Sierra or a newer version of the OS, Windows partition table format needs to configured as **hybrid** and NOT **protective**.
---
**FIRST STEP IS TO CREATE THE PARTITION**
Create a FAT32 formatted volume labeled "BOOTCAMP" on the primary disk. If this volume already exists, then erase the contents.
---
**CHECKING THE PARTITION TABLE FORMAT OF THE WINDOWS PARTITION**
This step is optional.
It is used to view and confirm the newly created Windows partition's partition table format.
This version of OS X adds a feature called System Integrity Protection (SIP), or less formally, "rootless." This system blocks access to the **gdisk** command.
In order to allow access following needs to be done first.
1. Restart Mac
2. Press Cmd + R when you hear the starting chine to open Mac in recovery mode.
3. From the top menu select Utilities > Terminal
4. type *csrutil disable* (don't forget to switch SIP back on by typing *csrutil enable* after all is done.)
5. restart Mac into normal boot.
Now that you have the necessary permissions continue with gdisk.
GPT fdisk installation is available here:

2. GDisk user manual: http://www.rodsbooks.com/gdisk/gdisk.html
Once the GPT fdisk is installed on the Mac, execute the following command:
Terminal
```bash
sudo gdisk -l /dev/disk0
```
and the result should look something like this:
```bash
GPT fdisk (gdisk) version 1.0.1
Warning: Devices opened with shared lock will not have their
partition table automatically reloaded!
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: present
Found valid GPT with protective MBR; using GPT.
```
If you see this, remaining part of the walk-through is **required**. MBR needs to show as *hybrid* in order to install Windows 10 on a Mac running High Sierra (AFS).

You need these in place before moving forward:
1. a flash/external drive connected to the Mac.
2. Windows 10 ISO.
