    Alright folks, newbie here to parellel OSing, so bear with me. Any help will be greatly appreciated.

    Say, i have a 2011 macbook pro with lion. i bought a optic bay drive and a SSD.
    I would want to install window 7 on the new SSD and keep running mac OS on my original HD.
    This is the kick, what is the extra procedures so i can run the two OS in parallel .

    The SSD needs a partition scheme of MBR, that's all. You can do this in Disk Utility, partition tab, option button, changing from the default of GPT, to that of MBR. Then partition the disk. Or you can do this from within Windows if you haven't already partitioned the SSD. Windows 7's installer will refuse to install on GPT disks.


    In any case, in the Windows installer you need to make sure you choose the correct volume on the SSD and reformat it NTFS. Disk Utility can't format the disk NTFS.
