    Hi all,

    I am new to Macbook and I am trying to install Windows 7 on my macbook using Bootcamp. These are the steps I have taken:

    1. Created a bootable Windows 7 Installation USB using "Windows 7 USB/DVD Download Tool" (Using an ISO)
    PS: I did the above using VMware Fusion
    2. Partitioned using Boot Camp
    3. Installed rEFIt

    Now when I restart my mac and try to install Windows 7, I get a black screen with the following error:

    Non-System Disk
    Press any key to reboot.

    At this point none of the keys respond.

    Please HELP!!!

    If you're only planning on dual-booting, I don't know why you'd need rEFIt, so as a start, you could try uninstalling rEFIt and see if you can install Windows then; it could be the issue.

    Could also be a problem with booting a Windows installer from a USB drive. Should theoretically work, but I've never tried it myself, and Boot Camp does actually do something to EFI to get it to recognize a Windows install disc. If, for example, you just partition the disk and try to install Windows without ever running the Boot Camp setup, it won't work.

    Hey Thank you for the reply.

    I tried uninstalling rEFIt and still does not work.

    I also tried Boot Camp to install Windows 7 but it does not recognize my USB as bootable.

    I followed a tutorial on youtube which tells me to install it using rEFIt

    You can not install Windows from a USB or external cd drive on a Macbook Pro.
