Running Win 7 x64 without BC on a MBP SR. I had already partitioned my hard drive to set up a test/recovery partition, so Boot Camp refused to play. The problem with the x64 release is that it won't boot properly on Mac hardware without some additional jiggery pokery, which I found
on this blog. You will need access to Windows to burn the iso, though.
As for drivers, they all installed absolutely fine using the x64 setup.exe file within the Boot Camp drivers folder. Make sure you install the latest drivers from Nvidia directly. My Windows score shot up after I did that. Windows update found some newer drivers - wireless and bluetooth I remember amongst others.
I used to own a DELL and in Vista, switching from the Balanced power plan to the battery-saver would dim the display, clock the cpu down (i.e. SpeedStep) and turn Aero off. That doesn't happen on the MBP and I'm not sure wether this is a driver limitation or a Windows 7-specific behavior.
Oh, and I'm running 64-bit.
Mine does. Something is borked on yours, it seems.
I tried for 4 hours yesterday to get Win7 RTM x64 installed on my iMac, but had problems and needed to blow away my initial BootCamp and re-install the 32 bit version.
Biggest issues were that the MacHAL and KeyAgent drivers weren't signed, so 64 bit won't let them install. This meant Bootcamp control panel wouldn't let me select which drive I wanted to boot with, meaning I couldn't boot back into OS X. I had to boot to the leopard DVD and use the utilities menu to get back to the OS X boot drive.
No need for any of this. There is a workaround for unsigned drivers, by force installing these and signing them with a downloadable utility before rebooting to stop Windows removing these on the the next boot. I wouldn't recommend it if you are not sure whether the drivers are likely to screw up your install or not.
As for selecting the default boot drive, you can use fdisk in Mac OSX or diskpart in Windows to do this.
Windows is easier:
Run command prompt in administrator mode and enter
diskpart
at the > prompt enter
select disk 0.
It will confirm that hard disk 0 has been selected. Now enter
list partition
This should list all partitions on your hard drive. The first partition is your hidden EFI partition, which is 200MB. The rest are your visible partitions. You will need to identify your OSX partition based on size. Note the partition number. Enter
select partition x, where x is your partition number.
Diskpart will confirm your OSX partition has been selected. Now enter
active. This will set your OSX as the default boot partition. Enter
exit and reboot.
