MSI z370-A Pro boot issue
Problem:MSI motherboard specifically MSI z370-A Pro model board has issue booting diskless due to driver issue. By default, Microsoft installs drivers which is what users use when they upload image. The driver provided by Microsoft is not good for diskless booting and thus make the client stuck at Windows logo.
a. You have to install NIC drivers from Realtek site and do not use Microsoft installed drivers.
b. When you install CCBoot Client in the OS before uploading image, do not click "Yes" button when it asks to optimize Windows.
