    i have a Mac Pro 1,1 i have mountain lion on one drive and it is the 32 bit. i have another drive that has Mavericks, YOsemite, and ElCapitan running 64Bit.
    my question, is if i boot to one of the 64 bit OSXs and use bootcamp from one of them and partition the first drive, would i be able to load Windows 10 64 bit that way?
    i have heard of many ways of doing this, but was wondering if that may work since the Boot EFI was already modified on the second hard drive.
    i have upgraded the firmware so it now reads 2,1 for the Mac Pro instead of 1,1 now

    Actually when you initial bootcamp app

    which will remind you only win 7 supported

    Precisely speaking win 7 32 bit optical

    installation was the only way.

    well i got it running,
    just an update, i got it working. i put the 4 OSX operating systems on one 1 TB hard drive. divided equal, and used carbon copy on one and Super Duper on the rest of the drives.
    then i used the old Mac Pro drive for windows. installed with that drive being the only one. installed my version of win 7 ultimate 64 bit modified, then i put the win 10 pro 64 dvd modified to do a upgrade. all it good, windows fixed the reboot problem, and now i have the anniversary version of windows 10 Pro 64 installed and running. it sees the 2 dual core and also sees the 32 gigs of ram.
    Hrutkay Mods was a big help in getting this done. he has tube videos and shows how to get this to work on the Mac Pro 1,1 and 2,1.
    i waited til after i got win 7 updated to win 10 pro, and running 64 bit, and it does show the processors.
    here is a post with my set up and screen shots after the install,
