So, for example, in the BIOS, if I select "Other OS" instead of UEFI I'm still in UEFI mode after rebooting? How does that work? Sorry, I'm a novice in this regard, I guess, despite the fact that I've put together hundreds of PCs. *edit* I've been fiddling with EBCD some more, using combinations of 2.3 and 2.4 with all three operating systems. I'm trying to replicate what were were discussing at the beginning of this post since chainloading is not an option in my case. I can access the Linux boot option on version 2.3 quite easily even in UEFI mode on Windows 7. I've reinstalled EBCD 2.4 on Win 8.1. I can boot to either o/s but not to Linux yet except directly from BIOS, which is an inconvenience. It would be very good to have all three listed in the boot manager and functional. Of course, the ideal would be the 5 second ESCAPE to LINUX option and I suggest Neosmart make some software that will do this as a matter of standard procedure. If you know how it works and if you can create it, I think it would be a very handy tool. Myself, I just stumbled upon it by accident. At first I could replicate it and I did so using my boot manager, the BIOS set to "Legacy and UEFI" / "boot Legacy first", and of course the BCD software from Neosmart. Alas, I can no longer replicate this, it seems. I'm going to keep trying though. Hitting the ESC key in Windows Boot Manager and instantly landing on one's Linux Desktop is a very gratifying feeling and certainly fitting in the literal sense of "escape".
