I have been running Windows 7 RC x86 (the 32-bit version) in Bootcamp for several months now. It’s worked well, but I really didn’t like that it couldn’t see the full 6GB of RAM in my MacBook Pro (Late 2007).
Snow Leopard comes with new Bootcamp drivers that support 64-bit Windows and adds a new file system driver to allow you to read your OS X files while in Windows. So I decided it was time to upgrade.
I quickly learned that I would need to to a complete reinstall. Microsoft doesn’t let you do an in-place install from a 32-bit version of Windows to a 64-bit version. Understandable. I don’t use the Windows setup for anything mission-critical, so it was not a big deal for me to wipe it.
Unfortunately, I could not get the Windows 7 x64 DVD to boot. After restarting and choosing the Windows DVD at the boot screen, the screen would blank out and just display “Select CD-ROM Boot Type” and refuse to continue.
After a little research I found out that I wasn’t alone and that someone had figured out a fix: the DVD needed to be tweaked a bit to work on the MacBook Pro I have. Apparently this MacBook Pro does not fully support 64-bit Windows. Here are the steps I used (from Sergio McFly‘s blog):
(Note that you’ll need to do this from a Windows machine. I did it from a Windows Vista VM in VMware Fusion.)
- Create 3 folders c:\efi-iso, c:\efi-exe and c:\efi-dvd
- Download oscdimg.exe and put into c:\efi-exe
- Unzip the Windows 7 ISO to c:\efi-dvd (7zip works great for this)
- Open a Command window
- Type: cd c\:efi-exe
- Type: oscdimg -n -m -bc:\efi-dvd\boot\etfsboot.com c:\efi-dvd c:\efi-iso\win7x64.iso
You’ll now have a new iso file in c:\efi-iso. Burn this iso to a DVD (I used Toast back in OS X).
This new DVD will boot just fine. From it you can install Windows 7 on your MacBook Pro.
But it doesn’t end there! You’ll want to install the new Snow Leopard drivers, so after everything has finished, insert your Snow Leopard DVD. This is where I ran into another problem. I could not run the Setup. It would tell me that “this model Macintosh does not support 64-bit drivers”.
Again, after a little research, I found the solution. The trick is to run the Snow Leopard Driver installer in compatibility mode:
- On the BootCamp CD open “Drivers/Apple”
- Right click on “BootCamp64.msi” -> Properties
- Go To “Compability” Tab, under “Compability Mode” check the box and select “Previous Versions of Windows”
- Now doubleclick on the “BootCamp64.msi” and install normally
After doing this, the drivers all installed and everything seems to be working great.

Thanks, I think this should work I just have been having trouble understanding what you mean by unzip the iso. Do you simply mean extract the contents? Could I do this with UltraISO or should I use a zip software such as winzip or 7-zip?
Thanks, I’m a little confused.
Yes, “unzip the ISO” means “extract its contents”. 7zip works fine to do this (and is freee). I haven’t tried UltraISO.
Nevermind, got it to work, THANKS!!!
Hey, I’ve run into another problem and trying to find a solution. Wondering if maybe you could help me out. I can’t find my Snow Leopard disc but I’ve made an image of it anyway. I’ve made it bootable from my external drive, but the problem is when I plug it into windows it won’t recognize it. So I can’t install the drivers.I’m about to install the trial version of MacDrive and go that route. Any better suggestions?
Oh, and I forgot to mention I’m not able to burn the image back onto a disc for some reason, it keeps failing.
Ok, so MacDrive didn’t work, it just allowed me to view the contents of the disc, but for some reason I couldn’t locate Bootcamp folder, nor the setup.exe file… Anyway, I ended up finding the Bootcamp drivers on torrent here http://thepiratebay.org/torrent/5054638/Bootcamp_Driver_3.0_for_Windows_32bit__amp__64bit_%28from_Snow_Leopard.
Success!!! Finally, after all that searching
. Although, I had to do something a little different once I burned the drivers to a disk. I’m running on a Macbook, so I can’t right click the .msi without the Bootcamp drivers. I had to use “shift+F10″ (which is the keyboard shortcut for right clicking). Everything else went as planned!
Hope this helps someone else!!
I have a Mac Pro 8 core 3.0ghz, I have windows 7 ultimate that runs in fusion 3.0 but I would like to use boot camp. When I try to install Windows to a dedicated internal drive I get almost all the way through the installation and after a few restarts I get a very quick blue screen, so fast I cannot read what it says. It then restarts again and gives me the option to run in safe mode. If i try safe mode I get a message that says Windows cannot finish installation in safe mode and then restarts. If I try normal mode, very fast blue screen and reboot. Any Ideas? I am going to follow the above to try 64 bit
Thanks a lot for this. Worked like a charm in my iMac. Windows 7 runs great!
I LOVE YOU!!!! Thank you so much it really helped B)
