"How do I completely remove mac os x on my macbook air and rather have my macbook windows based?"
DO NOT remove or erase the Mac OS X partition while booted to the Windows install DVD. The result would be that the drive would be changed to MBR partition scheme. It should remain GPT. Most versions of Windows cannot boot to GPT, but the hybrid partition created by Boot Camp Assistant takes care of that.
Here are the steps....
– Get a thumb drive and use Disk Utility to format it "MS-DOS" (FAT-32).
– Open Boot Camp Assistant.
– Follow the steps to download the "Windows support software" to the thumb drive.
– Unmount and unplug the thumb drive.
– Continue with Boot Camp Assistant to create the hybrid MBR partition called "BOOT CAMP".
– Insert the Windows DVD and lick the "Restart" button in the Boot Camp Assistant window.
– When it is done with all the copying files stuff that Windows installers do, select the "BOOT CAMP" partition and format it NTFS. DO NOT select the Mac partition for any reason.
– Install Windows.
– After a couple of restarts (Yes, Windows is still junky about installing), complete the setup of Windows.
– Insert the thumb drive and wait.
– When Windows asks if you really want to open the Boot Camp Setup, click "Yes".
– Install the Windows support software.
– For Mac OS X version 10.6.8 or older, boot to the OS X install DVD (could be marked "Disc 1").
– For OS X version 10.7 or later, boot to Recovery HD (Hold command and R keys during restart).
– Open Disk Utility and select the Mac OS X startup volume, select the "Erase" tab, select a format, and click the Erase button.
The format you select depends on whether you plan to install Mac read-write software in Windows or not. For Mac read-write software, such as Mac Drive or HFS+ For Windows (20 bucks), leave the format Mac OS Extended (journaled). Otherwise, choose MS-DOS. NOTE: This will result in poor efficiency for that partition. For much better efficiency, connect by Firewire or Thunderbolt to another Mac that has third-party NTFS software installed (read-write to NTFS), boot the Windows-Mac to target disk mode, and use Disk Utility to format the Windows-Mac's Mac partition as NTFS.
You can learn to use OS X in about 45 minutes if you have an open mind. The vast majority of PC switchers end up sticking with OS X and liking it.
