    I reinstalled OSX to a new drive. When I did it I lost the bootability of my Windows drive (SATA SSD).

    I have Windows 10 installed on a separate drive. It was installed without bootcamp. After the OS X reinstall the Windows drive no longer appears in the boot menu so I can't boot to it. The drive appears in OS X Finder and it has the files intact.

    Any idea how I can make it bootable again without reinstalling?

    This is what I get with diskutil list

    Code:
    /dev/disk0 (internal, physical):
       #:                       TYPE NAME                    SIZE       IDENTIFIER
       0:      GUID_partition_scheme                        *256.1 GB   disk0

    Wow, I had no idea that switching between EFI bootable and Legacy bootable was that easy.

    Thanks. Do you expect it to help? (as it's not free)
