MAC installation Win10 appears the solution to the problem of "on efi system, windows can only be installed to gpt partition"

Question:

These two days, I helped my colleague install WIN10 dual system on a MAC BOOK AIR (2015). When selecting the system partition, the prompt "Windows can only be installed to the gpt partition on efi system" appeared. I found many ways on the Internet but failed to solve it. Later, using a netizen's method, successfully completed the installation.

Solution:

1. Use bootcamp to adjust the win10 installation partition in MAC OS.

2, erase the new partition with disk tools, the partition format is selected as mac log type (remember! I've taken many detours here!

3. Restart the computer and press the option key to select the U disk or CD (create the WIN10 installation U disk or CD in advance) to start.

4. Enter installation, delete this disk when selecting disk, and then create this disk!

5, and then follow the prompts to install it.
