Finally. It works. Both OSs on laptop, I can boot to either. Both are stable but I'm not happy with the sloppy boot process that gets me there.
On every boot I initially get the GRUB loader, which is fine, that's what I want. From there I can boot into Ubuntu. At that point it also recognizes Windows 8 and provides an option to boot to it but that doesn't work. Instead I have to select the Windows UEFI choice and that will then lead me to the Windows MBR -- a double boot process so to speak. From there I am presented with the choice of Windows or Ubuntu, but Ubuntu isn't recognized, so I can only boot into Windows once I'm gone that far into the process.
I installed both OSs with UEFI and Secure Boot enabled but ultimately the only way I did get it to work though is by disabling Secure Boot in the BIOS. It's enabled by default on all new Windows 8 laptops/desktops. Certainly it has a potential of discouraging a less-than-technical person from ploughing ahead with the process beyond an initial attempt. It feels like yet another barrier to slow down innovation while raising the bar on protectionism higher.
Conclusion -- I'm not happy with the sloppy process to get there. Back to the drawing board. I'm going to wipe it all clean and start over from scratch yet again.
