    Ok so I have 2 hard drives on my Mac Pro (1,1) OS X on a 320GB and an empty 250GB. I wanted to install Windows 7 on the empty 250GB so I made a bootable USB with my MacBook Pro (as it is not supported to make one on a Mac Pro). I installed refit to boot from the USB and it shows up as a bootable device but I just get this error:

    Starting Legacy Loader
    Using load options from 'USB'
    Error: Not Found returned from legacy folder
    Error: Not Found from LocateDevicePath
    Error: Not Found from LocateDevicePath
    Error: Not Found from LocateDevicePath
    Error: Not Found from LocateDevicePath
    Error: Not Found from LocateDevicePath
    Error: Not Found from LocateDevicePath
    Error: Not Found from LocateDevicePath

    Error: Not Found from LocateDevicePath
    Error: Not Found from LocateDevicePath
    Error: Not Found from LocateDevicePath
    Error: Load Error while (re)opening our installation volume

    The firmware refused to boot from the selected volume. Note that external
    hard drives are not well-supported by Apple's firmware for lehacy OS booting.

    * Hit any key to continue *


    After that, the computer freezes (I can't continue by pressing a key) and I have to restart.
    Any Thoughts?
    Cheers,

    I could be way off base here, but I thought Win 7 didn't support booting from an external drive. I thought you needed 8.1 for external boot support.

    Again, just relying solely on what others have told me, I could be totally wrong on this.

    I thought of that until Bootcamp gave me the USB option for Windows 7 specifically. (attached photo)

    I read that to mean you can use USB as a media/driver installer drive, not a bootable OS drive. There again, I may be wrong, I've not tried it myself.

    After I created the USB it just said it was done, not giving me the option to install, but Ill definitely look into making it bootable.

    Ok so I did research, and turns out that should be bootable. I was looking at a guide to making a bootable windows usb on Mac, and the instructions are exactly what I did.

    I will. I thought it had to have UEFI support to boot a USB on the Mac. I rarely use windows for anything and have it on VM at the moment.

    Thats how I have it, but with 4GB ram total, its very limited. I only use it for a few programs but it would be nice to actually run it.

    You can't use a bootable usb from your Macbook Pro to boot your Mac Pro. The computer isn't just adding windows to the flash drive, instead it's also adding all the supporting boot drivers required to boot and install for your current hardware setup in your case the Mac Pro. In order to install windows on the Mac you need to run it from the CD or change the bootcamp files to make your Mac Pro create the usb bootable stick on its own.

    A quick google search found this video. This is the correct way to make a bootable usb. Once you do this it should boot fine.

    On the Mac you can basically take a disc out of any Mac & boot it on another Mac. However Windows is very picky about hardware & won't install the necessary drivers for another configuration if those drivers aren't necessary for your current configuration. It's a pain in the arse & makes backups & cloning discs problematic on Windows.

    cMP will only boot OS X from USB. anything else (DOS/Linux/Windows) only starts if it's on a disc or harddrive connected to one of the internal S-ATA ports.

    edit:
    you could try to boot the machine with Plop Boot Manager and then hop to the USB stick from there ->

    newer Macs will start non-OS X operating systems from USB, too.

    edit #2
    on MacPro1,1 an unmodified Windows 7 64bit DVD will not start. see here:

    This is true with discs, but with USB drives it's not and I'm not exactly sure why I just know from experience that It just won't work with windows: however it does with OS X for some reason.

    I actually tried the exact same method as the op but with different computers last year. On my MacBook Pro (had cd drive) in created USB from my 2013 iMac (no usb). It booted with errors similar to the op. I tried many different ways and they all failed.

    So then I found a way to edit the bootcamp file in my MacBook Pro and once that was done I was able to boot and install windows 7. I'm sure their could be other ways to get it to work, but this method was far the easiest and allowed me to install windows right away.

    Honestly since you have a CD rom already on the Mac Pro I'd just install it from the cd drive it's much easier. It's actually how I installed windows rently on my Mac Pro.
