On your Windows 7 PC or virtual machine of Windows 7. Making our USB Drive a bootable Windows 7 installation driveġ. We now have our Macbook Air and OS X Boot Camp prepped for our Windows 7 install. Once it finishes partitioning (probably will take about 5 minutes), it will ask you if you want to start Windows Installation or Quit and Install Later. Once your ready, click on the Partition button. Again, remember we limited and need about 10GB for Windows 7 itself. I personally only used 30GB for my Windows 7 installation since I will only be using it for VPN and some remote apps that have Windows only clients. Once the files are downloaded, we will be at the partitioning screen.
Next, it will ask us if we want to download the Windows support software, be sure to check it since we will need these files later for getting our mac hardware working in Windows 7 and click Continue and it will download the files. Notice how Boot Camp warns that you need an external cd/dvd drive not us! We will be doing two things here, partitioning our harddrive and also downloading the dmg file of our Boot Camp Windows files. Next, we will boot back into OS X Snow Leopard and run the Boot Camp Assistant. Once installed, be sure to reboot your Macbook Air twice the menu will not show up until after the second reboot (trust me, i noticed this first hand and after one more reboot could boot to my usb drive).ġ.

Hope this helps point you guys in the right direction.Using a windows 7 dvd, windows 7 pc and a usb drive, you can install Windows 7 on your Macbook Air.
I've upgraded my own firmware before because Apple provides Firmware updates directly on their website along with SMC updates.

Someone mentioned that Apple is the only entity that can upgrade your firmware and this is not true. Why? Because they can boot from their network server and directly load firmware and OS X without any USBs and Disks. For example: because an installer for some MBP doesnt work for iMac) and when the USB doesnt show up the quickest solution is to take it to the Apple store. I ALWAYS use my special Recovery Disk Assitant USB drive I created (and I only use this one because different model macs have different builds and when it downloads the new OS X from the apple server it automatically chooses the correct osx build for your mac. Even some of the newer models (especially 2009-2010). I've work on various macs and I have noticed that some of the intel-based macs sometimes will recognize the bootable USB drive and some will not.

I can assure you that my usb port is functioning correctly (at least during Mac OS X run time). Is it possible that my model is too old such that it doesn't allow booting from USB during boot time? Is it possible that older ROMS do not check for USB drives during boot time (hence explaining why my usb doesn't light up)? I thought my ISO is not bootable so I tried another windows 7 ISO and the results remain the same. Normally the usb stick will light up when inserted into this usb port. Strangely, I noticed that my USB stick does not light up when I unplugged it and reinserted it when my mac is in the boot menu. I tried removing the USB stick while I am still in that menu and plugging it back to see if that will fix the problem. I only see my normal boot partition and a recover partition. Somehow, my usb stick doesn't show up in the boot menu. I pressed option during boot to go into the boot menu. I plugged in my usb and restarted my laptop. I went through bootcamp's "Install or remove Windows 7" option and partitioned 21GB from my harddisk for my windows partition (it's named "BOOTCAMP", MS-DOS (FAT)). I created a windows usb with bootcamp assistant, "Create a Windows 7 or later version install disk" with a windows 7 ISO image.
