Cannot make my Bootcamp disk valid for W8 install after formating in win setup, what is wrong?
Also i dont get the option to choose partion size before BC boots the first time...
Mac Pro OSX 10.11.3 - Windows 8.1 on DVD
Mac Pro, OS X El Capitan (10.11.3)
Bay # 2
Would it matter as long as it boots up and enter setup menu?
How about using a usb docking with my 3.5 drive and use my MBP for setting it up, and then putting it back in my MP, will that work?

The important part is whether or not the Windows Installer can see this disk in Bay 2. In Windows Installer, if you scroll vertically in list of available disks, are all connected disks available?

Installing Windows is a pain on external disks. Unless absolutely necessary, this option should be the option of last resort.
Yes, all connected disks are available, or in this case, just one when i unplug the OSX disk also, but the disk also shows a partion on 200mb, is that normal? EFI?
Btw, i never see EFI disk when i enter bootmode, why?
The EFI partition is normal on GPT disks as used on Macs. If you have only the designated Windows disk and boot from DVD, do you see the disk?
No, theres no EFI disk showing when i boot up.
Is it possible to post a screen shot of what you see?
If you physically remove the SSD, leaving only the designated Windows drive in Bay 2, and then select the Windows DVD icon, does the installer start? If yes, what are the available disks in the Windows Installer? It would be good to see the Windows Installer screen in this configuration which may need another photograph.
If you want to remove your image, you can use the camera at an angle to the screen pointing away from yourself. 😉
Installer start if only designated drive and win dvd is connected yes.
Heres all the setup screens.
There are two drives available when only win dvd and designated drive is plugged in, the drive 0.
(Didnt want to get down under my desktop and open it and disconnect again now, but it looks like that when only one is connected 😉 )
Sorry about the orientation here, dont know what happened after upload
You have two different issues.
1. Windows on your specific Mac can be installed using legacy BIOS/MBR only. EFI Boot may not work properly. You have a designated disk which is larger than 2TB, which a BIOS/MBR installation does not support.
2. Your disk is currently GPT-only.
You have two choices.
Create a FAT partition in the first 2TB of the disk and install Windows and leave the remainder as HFS+, or, create a FAT partition larger than 1TB which will limit the MBR to less than 2TB and it will create a MBR as necessary when partitioned with FAT and then you can click on Format for the designated partition and let the installer convert it to NTFS and install Windows.
The partitioning can be done for both options using Disk Utility or Terminal diskutil commands.
Ill try now.
Can i use ExFAT also?
Yes, either should work.
Hmm, now im confused, when i try to partition the disk, i cannot change part size before i choose OSX journal and the FAT, but after part finish and it says successful, then its still back to 3 TB with no partition 😕
If this is meant to be used only for Windows, then create two partitions, the first one should FAT/exFAT of 2TB or less, leave the remainder as JHFS+.
Windows only yes, but JHFS+, what is that?
And why doesnt partition work?
GPT Error: Windows cannot be installed to this disk
