After having tried everything simple, I've arrived at the following scenario:
A blank SSD (internal) to work on.
An externally running Mac OS installation to do all the work from (and later clone back).
Goal: SSD: | Mac OS | Windows 8 |
Since the other variants all failed, I'm installing with Parallels on a physical volume, i.e. a Windows partition created with diskutil (as Boot Camp would do it).
This goes through fine, but now I just can't find any way to actually boot this volume.
I tried dd'ing the PhysicalMbr.hds to the disk, I tried gptsyncing GPT and MBR, but actually I don't know what the final hybrid GPT/MBR should look like and how to achieve it.
Since I have all the freedom to work on this disk with no data to loose there, it's really "just" a matter of writing the proper boot record. Yet, I don't know any further on how to get it right.
A solution would be greatly appreciated!
EDIT
I settled and solved it in hardware, meaning I took out the HD and put the SuperDrive back in for installation. This took so much less time then all this trying around to get the boot record right. The disadvantage is that the boot disk (SSD) has to be where the hard disk was, so it's now in the mechanically better slot, whereas the spinning hard drive is where the super drive used to be. It will only boot windows like that, but I put in some rubber and it's totally fine. Thermally, it's even better then before since the HD doesn't receive all the heat from the CPU.
Also, I settled for Windows 7 since I couldn't get the Boot Camp drivers to install for Windows 8, despite that I tried all the tricks one can readily find.
TL;DR: Going for an officially supported configuration by putting back in the SuperDrive and using Windows 7 is probably the fastest (and time-wise most predictable) way to install Windows on these MacBooks with HD+SSD.
