Ok, so I am no MacBook specialist, but someone I was talking to was complaining about the amount of time it took to install Windows 7 via Bootcamp on a MacBook via a DVD.
So I got a hold of a MacBook, my wife got one for a broadband promo, and embarked on the challenge.
1. Partition the drive using BootCamp Assistant: This step is simply to help to partition the drive so you can choose to run either OS at startup. The *ISSUE* is that bootcamp does not recognize a USB key as a viable installation path, so that shot that down. I hope that this gets fixed at some point, as I love installing my PCs via USB, its very fast.
2. Download a free tool called rEFIt: This tool essentially lets you to have better control of where the Macbook will boot from when you restart. Once you have this installed, you can then restart the machine, then as it starts back up, you can hold down the “Command” button to choose the “Install Windows from” option. This will then detect the USB as an installation media.
3. Follow the prompts of the normal Windows 7 install: That's the simple part. The installation to a usable OS took just over 15 mins.
So there you have it, installation of Windows 7 from a USB drive on to a Macbook, simple and hassle free… now!
