Setup1.x on Mac with El Capitan/WIndows 10 (BIOS/MBR issue)

[johnmoore64]

Computer: Mac Pro Desktop (Cylinder) with 12-core Xeon, 64GB Ram, internal AMD FirePro D700 Dual, 1 TB SSD.

eGPU: eVGA Nvidio 980 TI, AkiTio Thunder 2, 300W power supply, riser, etc.

 

Running latest El Capitan and installed Windows 10 via Bootcamp prior. Works perfectly in Mac/El Capitan. Windows 10 giving Code 12 for the 980 TI.

 

Purchased @Tech Inferno Fan Setup1.3  (Sorry to hear about the accident Nando4  ). Instructions clearly say needs partition to be MBR/BIOS and I have GPT/UEFI. Also says set BIOS to CSM/Legacy. Decided might be a good opportunity to clean house, so instead of mucking with things I backed up all my data, wiped the drive and did a clean install of El Capitan. During the install it asked me what type of partition. I tried to select MBR, but it told me it could not install El Capitan on an MBR partition, so I'm stuck at GPT again.

 

Questions:

• Can El Capitan install on an MBR partition on a Mac?
• I'm not familiar with any way to get into Mac BIOS to change mode to CSM/Legacy - is that possible?
• If El Capitan and Windows 10 will both work, what's the best method to convert partition?
• Is there a more preferred way to install Windows 10 for dual boot vs using Boot Camp?
• Should I be using an earlier version of either OS to make this work, or have both been tested with Setup 1.3?

 

Thank you for reading! I have a shiny new Vive just sitting here collecting dust, and a powerful PC with underpowered video. Sad day.
