移除macOS，只安装Windows 10

How do I remove macOS completely from my MacBook Air 2015 and install Windows 10 only after?

I have tried formatting my drive to GPT and tried booting a Windows Installation USB however I'm stuck at the installer not being able to find any drives.

I've just succeeded in replacing OS X with Windows 10 on a late 2018 MacBook Pro with the touch bar.

NOTE: you'll need an external USB keyboard (and perhaps mouse) because MacBook's ones won't work before you install the drivers. Steps to follow:

Open the Boot Camp application on OS X and download the Boot Camp Support Software, i.e. a package containing all the Windows drivers you'll need to install and smoothly run Windows 10. You can download that package via the Action menu entry in the Boot Camp application.

Copy the content of the package to the root of a FAT32 USB pen (a 8GB pen will do the job).

Create a bootable USB Windows installer. I made it on another Windows 10 machine, but I guess it's possible to make it on OS X too.

Insert the Windows installer USB pen and reboot the MacBook Pro. Hold down the Option key until a boot menu appears. Boot from the Windows installer.

Chose the Custom installation. You'll be asked to chose the drive where to install Windows to, but you probably won't see any storage device. Hence, insert the Boot Camp drivers USB pen and press Load drivers. There, you can browse the pen and select the Apple SSD driver (I don't remember what is the exact folder you have to select, but it's not hard to find out).

Once the driver is installed, you can finally see your hard drive partitions. I deleted the OS X partition and created a new NTFS one.

Complete the installation. Once Windows is booted, run the setup.exe executable in the Boot Camp USB pen. That will install all the needed drivers (network, keyboard and touch-pad, ...).

Enjoy.
