    How to boot to a secondary partition?


    I have a second partition that I would like to install windoiws 7 pro on, but am not sure how to go about it, and once I do install it, how do I boot to it?

    So, my questions are-
    How do I install Windows 7 on this second partition
    how do I boot to it

    I know on my mac with boot camp I just hit the alt button and I have the choice of which OS to run.




    Thanks

    You can install the windows 7 to the second partition by booting from the DVD, then selecting Windows 7 on the boot menu after you have successfully installed windows 7 on dual boot.

    Do you know if you are booting via UEFI or legacy-BIOS? You can check pretty quickly by starting up "disk management" (just type that in the start screen and it'll pop up in settings as "Create and format hard disk partitions") and checking whether your hard drive is formatted as MBR or GPT. Right click your drive in the lower list (it will probably be disk 0) and click properties, then check the "Volumes" tab, it will list a "Partition style": MBR means you are booting with BIOS, GPT means you are booting with UEFI. (At least, it does in Windows).

    If it's via UEFI, Windows 7 supports booting but isn't quite as compatible so you may have to make sure things like Secure Boot are disabled.When you install Windows 7, boot from the DVD (or USB?) and select "custom installation" and you should be able to choose your second partition as an install location (select it, click next). This will set up Windows 7 as the default (and only) boot option, so if you are using UEFI you must also have a Windows 8 installation DVD or preinstall environment so you can install the Windows 8 bootmgr again.

    If you are using BIOS you can just use the windows 7 bootmgr and add a windows 8 entry to the bcd, use something like easybcd or visual bcd editor, it's fairly straightforward. If you do have to reinstall the windows 8 bootmgr, rebuild the bcd in the recovery environment (look up how to repair a damaged bcd, it's the same steps: basically cd C:\boot, attrib -s -h -r bcd, ren bcd bcd_old, bootrec /rebuildbcd, which should scan and find the Windows 7 and Windows 8 installations and add them to your boot options).

    IMHO even if you are using BIOS the windows 8 bootmgr is a little slicker so you'll probably just want to use it regardless.

    You would be much better off starting with Win7 installed on the first partition. Running Win8 core or Pro? What sort of install medium do you have for Win7? Was it an upgrade? of an OEM preinstalled machine or not? Is your Win8 preinstalled by an OEM? Was is an upgrade? Are you running UEFI? Do you have a second hard drive you could install on rather than another partition? Here are some links to get you stared on thinking about accomplishing what you want.

    The computer originally came with 7 home premium and I upgraded to 8 pro. I do have another drive but it's not completely empty and it's an external. Not sure if that matters

    Please ignore the drive comment since it is an external. Don't recall if it came any other way, but I take it that your Win7 Pro is a full-install version.
