To use any of these key combinations, press and hold the keys immediately after pressing the power button to turn on your Mac, or after your Mac begins to restart. Keep holding until the described behavior occurs.
To start your Mac using your NetBoot image: Restart your Mac while holding down the Option key. Holding down the Option key reveals all the drives, including. Use the arrow keys to select your NetBoot image. Press the return key. You should now see an Apple logo with a spinning globe beneath it. You should be able to see the boot menu of Mac, choose the 'Windows' one. Now you should be able to see the boot menu of Clonezilla live. Choose 'Network boot via iPXE', and if your network device is supported by iPXE, you should be able to PXE boot it now. MACs do not use 'exactly' PXE; they use a similar environment called Boot Server Discovery Protocol (BSDP). The OS X Server includes a system tool called NetBoot. A NetBoot client uses BSDP to dynamically acquire resources that enable it to boot a suitable operating system. Starting with the release of macOS Lion in 2011, Macs have offered a Recovery. Start the PC into PXE network boot mode (not sure if that's what it is called) The PC will find the hosted files and allow you to install the OS (or anything of your liking) onto that computer.
- Command (⌘)-R: Start up from the built-in macOS Recovery system. Or use Option-Command-R or Shift-Option-Command-R to start up from macOS Recovery over the Internet. macOS Recovery installs different versions of macOS, depending on the key combination you use while starting up. If your Mac is using a firmware password, you're prompted to enter the password.
- Option (⌥) or Alt: Start up to Startup Manager, which allows you to choose other available startup disks or volumes. If your Mac is using a firmware password, you're prompted to enter the password.
- Option-Command-P-R:Reset NVRAM or PRAM. If your Mac is using a firmware password, it ignores this key combination or starts up from macOS Recovery.
- Shift (⇧): Start up in safe mode. Disabled when using a firmware password.
- D: Start up to the Apple Diagnostics utility. Or use Option-Dto start up to this utility over the Internet. Disabled when using a firmware password.

If a key combination doesn't work
If a key combination doesn't work at startup, one of these these solutions might help:
Network Boot Server Mac
- Be sure to press and hold all keys in the combination together, not one at a time.
- Shut down your Mac. Then press the power button to turn on your Mac. Then press and hold the keys as your Mac starts up.
- Wait a few seconds before pressing the keys, to give your Mac more time to recognize the keyboard as it starts up. Some keyboards have a light that flashes briefly at startup, indicating that the keyboard is recognized and ready for use.
- If you're using a wireless keyboard, plug it into your Mac, if possible. Or use your built-in keyboard or a wired keyboard. If you're using a keyboard made for a PC, such as a keyboard with a Windows logo, try a keyboard made for Mac.
- If you're using Boot Camp to start up from Microsoft Windows, set Startup Disk preferences to start up from macOS instead. Then shut down or restart and try again.
Remember that some key combinations are disabled when your Mac is using a firmware password.
