Using a Mikrotik router to boot and install Windows

Lately I've been using Mikrotik routers because they're cheap, powerful, and fast. Most of them have either a USB or MicroSD slot, so you can add enough space to store network boot images right on the router.

I got most of the tips needed from these two articles, and combined them into this step by step guide:

	#define GET_CAN_EXPAND "sudo raspi-config nonint get_can_expand"
	#define EXPAND_FS "sudo raspi-config nonint do_expand_rootfs"
	#define GET_HOSTNAME "sudo raspi-config nonint get_hostname"
	#define SET_HOSTNAME "sudo raspi-config nonint do_hostname %s"
	#define GET_BOOT_CLI "sudo raspi-config nonint get_boot_cli"
	#define GET_AUTOLOGIN "sudo raspi-config nonint get_autologin"
