    I've installed Windows 8.1 to my Macbook Pro 15 mid 2012 via legacy mode, all went ok. It was installed to disk1s1 (HDD in optical bay), my OS X 10.11 sits in my SSD (disk0) on the main bay.

    Disk1s2 is a data partition.

    I can see the Windows drive if I press alt during EFI boot, but when I try to boot it, says:
    My HDD is MBR and my SSD is GPT.

    Code:
    /dev/disk0 (internal, physical):
       #:                       TYPE NAME                    SIZE       IDENTIFIER
       0:      GUID_partition_scheme                        *250.1 GB   disk0
       1:                        EFI EFI                     209.7 MB   disk0s1
       2:          Apple_CoreStorage Macintosh SSD           249.2 GB   disk0s2
       3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3
    /dev/disk1 (internal, physical):
       #:                       TYPE NAME                    SIZE       IDENTIFIER
       0:     FDisk_partition_scheme                        *500.1 GB   disk1
       1:               Windows_NTFS Untitled                128.0 GB   disk1s1
       2:                  Apple_HFS FCBD                    372.1 GB   disk1s2
    /dev/disk2 (internal, virtual):
       #:                       TYPE NAME                    SIZE       IDENTIFIER
       0:                  Apple_HFS Macintosh SSD          +248.8 GB   disk2
    
    If I remove my SSD, Windows boots normally and I can work all day.

    How to boot with both drives connected?
