Apple documents state my MacBookPro2,2 2006 Core 2 Duo 2.16 MHz will not run Windows versions newer than Vista. However, I burned a 32 bit Windows 7 ISO to a DVD, after converting the ISO to DVD/CD master in the Disk Utility. The resulting DVD worked. I tried same procedure with a 32 bit Windows 10 ISO. The Mac froze at a black screen with a message asking for a boot choice 1, 2. Why did booting from the Windows 10 DVD fail?
I understand that my Mac has a 32 bit EFI, but the processor is 64 bit. I also understand there are issues with booting from an USB flash drive, which is why I used a DVD. Are there other methods to install newer versions of Windows on my Mac?
Best Answer
You model Mac can only support only one boot method when booting from the optical drive. The 32 bit Windows 7 installer ISO provide by Microsoft can only be BIOS booted and therefore offers no problems when burn to a DVD. However, any of the Windows 10 installer ISO files provided by Microsoft can be either BIOS or UEFI booted. Using a DVD burned from one of these ISO files to boot your Mac will result in your Mac hanging as described in your question. This is true for both the 32 bit and 64 bit versions of the Windows 10 installer ISO file.
Several answers involving installing Windows 10 on your model Mac have already been posted. See the question Installing windows on a MacBook Pro 15-Inch “Core 2 Duo” without Mac OS X.
Note the following:

Install the Boot Camp Support Software (Windows Support Software). The Boot Camp Support Software is on the Snow Leopard installation DVD. The files can be accessed from Windows. Officially, only 32 bit versions of Windows can be installed on your Mac. Since I do not have your model Mac, I can not predict how difficult it will be to the adapt the software for use with a 64 bit Windows. You should consult lx07's answer for more information.
A Snow Leopard (OS X 10.6) ISO file can be downloaded from the website Mac OS X Snow Leopard Install DVD. You should verify the download by computing the SHA256 hash value. The
Get-FileHash
Power Shell cmdlet can be used to compute a SHA256 hash value. EnteringGet-FileHash
along with the path to the downloaded file in a Power Shell window should produce the following SHA256 hash value.Under Windows 10, the Boot Camp Support Software can be accessed by mounting this ISO file.

Setting BIOS Booting as the Default
If a BIOS booting Windows is the only operating system installed on a Mac, then the Mac should automatically boot to Windows. However, if BIOS booting has not be set as the default, there may be a delay before booting begins. Otherwise, the Mac Startup Manager can be used to boot Windows. Below are two methods for setting BIOS booting as the default.
Method 1: Boot from an OS X (macOS) installation DVD or USB flash drive, open a Terminal window and enter the command given below.
The version of OS X (macOS) chosen must be compatible with your Mac. The instructions for creating a Snow Leopard (OS X 10.6) installation USB flash drive can be found here.
Method 2: A successful installation of the Boot Camp Support Software (Window Support Software) will include the creation of the Boot Camp control panel for Windows.
