Remove Mac OS X and install Windows?

I'd like to run a new 11.6" MacBook Air exclusively on Windows 7 without wasting any 'space' on the Mac OS. Is there a SIMPLE way to install Win 7 and completely erase Mac OS?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

I believe it's possible with Boot Camp. I used Google with your question and a LOT of stuff came up. You might want to read up about that. – user3463 Nov 22 '10 at 16:33

Yes, attach a CDROM drive, boot from MacOS (hold down the C key while the device boots). When The install routine starts, select your language and go to disk utilities at the top of the screen.

Select the partition on the left, and erase it. Restart the computer with Win7 in the Rom drive. Install Win7 remembering to delete the largest partition on the disk (the old HFS+ partition created by OS X), and put a new NTFS one on it.

Complete the install of Win7. Congratulations, downgrade complete. ;)

I believe that you had a typo in there (the downgrade part). I think you meant upgrade. Good directions though! +1 :D – David Nov 22 '10 at 16:37
Riiiiiiiight :) – Everett Nov 22 '10 at 16:38
Thanks Everett! If only everyone communicated as clearly as you do... Any suggestions as to how I should partition the 160 GB hard drive? – Eshel Nov 22 '10 at 17:17
Harrymc does have a point. On one hand, it's not a bad idea to have a backup OS. However, in order for this to be useful, you have to have the content of your HD readable by the OS. This means formatting FAT32. You won't be able to store files above 4GB. You can't format ExFAT on an internal drive and have Win7 recognize it. If you format NTFS (Win7 likes this) then you have to add software to OS X to make it compatible. There is a security risk to be addressed for having a "backdoor" OS on a system too. – Everett Nov 22 '10 at 17:46
Ouch, this is way over my pay grade. Bottom line, in case of trouble, can I simply boot the Mac OS from the USB device which is included in the original package from Apple? At the risk, of course, of losing all Win 7 data, which will be backed up anyway. – Eshel Nov 22 '10 at 18:09
