Boot Windows® PE Media on a Mac® without Boot Camp®
The following methods should be used when booting a Windows® Preinstallation Environment™ or Windows® PE (WinPE) image using a WinPE USB / CDROM built with the WinPE Image Creator build tool.
USB Booting
Do not insert the Eurosoft WinPE USB Program Device before booting.
Reboot. Hold down the Alt/Option key during reboot.
Clean boot. Hold down the Alt/Option key during boot.

When the graphical boot menu appears, insert your Eurosoft USB Program device. The Apple® Mac® Start-up Manager will update as needed.
If an EFI Boot USB icon does not appear, reboot and hold down Alt/Option during reboot.
When the EFI Boot USB icon appears in the graphical boot menu, hit Enter to select it.

Proceed through the Windows PE boot and run Pc-Check Windows when Prompted.
Note:
The Mac Start-up Manager works well if you have a number of boot options from which to choose, but your Mac also recognizes a few additional start-up keys that direct it to boot immediately from a specific source. These keys include holding the C key during boot to boot directly from an inserted CD, DVD, or bootable USB drive.
