I have a large USB drive that I would like to use to multi-boot several Windows products. The way my project seems to differ from every other thing I have found on Google is that I want it to work seamlessly with Secure boot enabled, and I'm not trying to boot Linux.
I have four items that I want to boot: Windows 8 x86 and x64 installation discs, and WinPE 4.0 x86 and x64. Later, I might wish to add Windows 7 and WinPE 3.0, but that isn't necessary at this point.
The problem that I have is that I am unable to choose the item that I wish to boot, because there is no boot selection dialog that I can find anywhere. I am able to create the USB with multiple .wim files in the sources folder, and I have even been able to use BCDEdit to modify BCD for multiple OS entries - but none of them ever show up!
How can I fix this problem? From a single USB drive, I wish to be able to install Windows 8 or boot from a PE.
