I installed Windows 7 (Build 6801) on my MacBook “Core 2 Duo” 2.0 13″ (Black) with 3GB RAM.
To manage the boot menu for my Vista and Leopard partitions, I use rEFIt instead of Boot Camp. After I made a backup disk image of the Vista partition, I booted the Windows 7 DVD, reformatted the Vista partition and began the installation. It went a lot faster than the Vista install.
The Boot Camp drivers from the Leopard DVD installed without any problems in Windows 7 – the Apple Built-in Bluetooth, the Apple Built-in iSight, the Apple Trackpad Enabler, the Apple Keyboard, the Apple IR Receiver, the Atheros AR5008X Wireless Network Adapter, the Marvell Yukon 88E8053 PCI-E Gigabit Ethernet Controller, the SigmaTel High Definition Audio Codec and the Boot Camp Control Panel. Windows 7 installed the Mobile Intel(R) 945 Express Chipset Family (Prerelease WDDM 1.0 Driver) for the display adapter.
I used Randy’s SharpKeys 2.1.1 (a registry hack) to remap the Apple enter key (on the bottom row) to a forward delete key so I don’t have to hold down the fn key and delete for that function. I also mapped F8 to Prtscr – another Windows key that’s missing on the MacBook keyboard.
Thankfully, my two year old MacBook still feels responsive in Windows 7 (and in Vista). I’ve never had any major problems with Vista, and so far, Windows 7 seems to be an improvement.
