As I have bot seen any real topics about this, I figured that I would post my experience with the new windows 7 beta on my aluminum macbook 2.0ghz, in bootcamp. Process is simple if you sign up for the beta, just download the 32 or 64 bit versions of Windows 7 beta, build 7000, and burn the iso to a single layer dvd using Disk Utility. Forget what apple says about 64bit windows OS's and the macbook, as you can follow one simple step to enable the boot camp assistant to install the 64bit macbook drivers. After burning the w7 dvd, open boot camp, and follow the instructions as you would with Xp or Vista. The installer works the same as vista, so no surprises there. Immediately after Windows 7 installs, insert your OEM leopard OS disk and run the setup file that you are prompted if you are using the 32 bit Beta. If you are running the 64 bit beta, then follow this simple step: In the Windows 7 Start Menu Type “cmd”, then right-click on the program that appears and choose “Run As Administrator”. Then enter; D: cd "Boot Camp\Drivers\Apple" msiexec /i BootCamp64.msi This will bypass the apple lame-brain that says that the new fully capable Macbook cannot run a windows 64 bit OS. (not true) Once the boot camp assistant installs all the drivers for your system, then you are up and ready to go. All components seem to work fine, with no driver issues, and no yellow flags in the device manager. Running Windows 7 on my Macbook with the 2.0 processor and 2gb of ram on a 32gb partition, is extremely smooth and responsive. I can attest to the fact that this OS is faster than vista, even after all my programs have been loaded. I really believe after playing with the beta that MS is on the right track with this, as i have had no compatibility issues. Of course my right click option on my glass track pad does not function, just as it was broken in vista. I really believe that this is an apple driver issue. Just thought I would share my experience.
