Installing Windows 7 Ultimate on Lion/Bootcamp 4/Mac Pro (before 2008)

What is helpful

Did you burn the DVD or not? 32 bit or 64-bit?

Your Mac Pro 1,1 has trouble booting a Windows 7 64-bit DVD

2GB is 'undernourished' for Mac OS as well, minimal.

Windows 32-bit would also ony support 1.9GB RAM, catch-22 to get 64-bit installed

It is pre-2008.

Load Windows into a VM like VirtualBox, to reburn a DVD that boots.

Why install Windows? it is going to take work.

Still...

Retail Ultimate comes with 32 and 64-bit media on DVD

Burning an ISO will fail if you dn't burn at slowest speed

your Mac would run better with 4 x 1GB or 2 x 2GB plus 2 x 1GB

Given the RAM and having hopefully ATI 5770 1GB VRAM you will be thrashing pagefile from too little memory

And you need to save the DVD to disk, modify it with Imgburn from within a running copy of Windows - so you may need to use VirtualBox as an intermediary step.

Windows 7 64-bit requires UEFI, which means Mac Pro 3,1 Early 2008.

That is what Microsoft supports for UEFI and GPT on 64-bit OS, www.uefi.org group, Intel, Apple and other partners.

And the ROM yu have is 32-bit and too small for that. UEFI didnt' exist until two years after the MacPro line debut.

So the easy way: install Wndows on a PC to get it started, don't update, then insert drive into Mac Pro and continue from there. That is the easy route.

You actually should, with 64-bit DVD, get an error message:

Select CD ROM 1 or 2

I had Windows 7 evaluation copy, on my computer, which was expiring. Bought the Windows 7 Home premium and put the disk in the CD-Rom drive, and started my computer. Got the "Select CD-Rom Boot Type" prompt with the options "1" and "2", with no descriptions for either one. I entered the number '1' and my computer started with the evaluation copy (tried '2' as well). Finally, I started the computer again and entered the number '3'. Installation process for my Windows 7 home premium started.

Someone put this help tip and it should be useful, but does require Windows, and it is easy to install Windows from ISO or DVD into a VM whereas native install fails.

Again, you only need Apple drivers, not Boot Camp Assistant to partition etc and you do need to put the Windows drive in bay #1 or #2 while removing all other drives (external as well).

Try typing "3" though if you get the "Select CD" prompt first, seems Microsoft has for years had an issue with their loader is not ISO9660-compliant.

And if it was my Mac, I'd download Windows 8 Preview on the 29th (well, wait a couple days for the server to catch up as it will probably get million downloads a day). Unless you have access to Windows 7 through work or MSDN.

You only need to buy System Builder Windows 7 64-bit Pro - Pro to use both processors in your system.

And normally installing 32-bit version is a piece of cake. and from in there you can install 64-bit in another partition on same hard drive without having to boot off DVD.

I think you created the DVD with Disk Utility and that is why it doesn't work. No?
