    Hello everyone, I just got Windows 7 64 bit on my Mac Pro 1,1. I used oscdimg to modify the ISO and activated it using my product key. I am downloading Windows 10 right now. I would like to get my Mac Pro 1,1 up to Windows 10. Once I do the upgrade, will I have the 64 bit version? And will it work with my Mac Pro?

    I appreciate any response I get!!

    Hi there, thanks for your reply!
    My computer has an 32 bit EFI, so I used oscdimg to make it so I can use all my RAM. If I upgrade to Windows 10, I'll have 64 bit Windows 10 and it'll boot properly? I'll be able to use all my RAM?

    Sorry for asking again, I want to make sure you and the others understand my situation. :)

    Yes and yes, assuming you are upgrading from 64bit w7 or doing a fresh w10 install.

    Can someone suggest a guide to do a FRESH install of Windows 10 64-bit on MacPro1,1 using bootcamp, WITHOUT first installing Windows 7? I can't find any reliable info. I presume that I have to edit the boot to enable 64-bit so the boot CD will not hang on booting MacPro1,1's 32-bit EFI.

    Please help!

    Create partition using bootcamp or something, then restart computer with windows 10 disk and load from disk then install on the partition you created.
