How to deal with the GPT partition when installing Win10 system

Many users who have installed the Win10 system will encounter this situation, that is, during the Win10 system installation process, the installation program prompts the system to be installed on the GPT partition. But users can't immediately convert the disk partition to GPT format, so how to avoid this problem?

In fact, the bootmgr.efi” and the folder "efi" file in the Win10 installation CD cause the forced start UEFI+GPT installation mode, and what we have to do is to avoid UEFI detection and let the system install in BIOS+MBR mode.
In fact, the method is also very simple, we just need to re-edit the Win10 ISO installation file and then burn it into a CD or write to a USB disk to install.
1, use the "UltraISO" CD image tool to open the Win10 ISO installation image;
2, after opening, delete bootmgr.efi” and folder <;efi”;

3, last Save the ISO image, then write to the U disk or burn it to a disc.
This way we use our own Win10 ISO image to install, during the installation process, the installation program will not prompt to install to the GPT partition.
