The Gandalf WinPE ISO Gandalf's Win10PE x86 Redstone-11-07-2016_x64.iso cannot be easily booted using Easy2Boot (or any similar system).
This is because the filename used by Gandalf contains spaces and there is a bug in the MountPEMedia.exe utility used by WinBuilder PE's - they will not load the .ISO file as the Y: drive if it uses a .ini file and the .iso file contains spaces in the filename.

Note:
If you use E2B v1.90+, then Gandalf and other WinBuilder-based WinPE ISOs will just work! Simply ensure that there are no spaces in the filename and that the file extension is .iso (not .isodefault).
