I have a macbook air, I installed windows 7, no problem.Succed, but drivers nothing, I've been looking on the internet Anyone got a solution?

Welcome to the Apple Support Communities

You have to install Boot Camp drivers in order to get the best performance and to use all the hardware.

You don't specify what Mac OS X version you use, and it's really important for us to know it because there are different ways to install Boot Camp drivers, but as you have installed Windows 7, I understand that you are running Snow Leopard or a newer version.

To get the Boot Camp drivers, first start in OS X (hold the X key while your Mac is starting). Then, open "Boot Camp Assistant", press "Continue" and tick only the option to download the Windows support software. It will be stored on a DVD or USB drive.

After doing that, restart in Windows and install them in Windows, so you will get your sound card, AirPort, graphic card, etc. running

You are in the worst scenario, because now you have to delete Windows 7 and get back OS X Mountain Lion. Next time you install Windows through Boot Camp, be very careful with the partitioning step, and follow the steps of this site > http://manuals.info.apple.com/en_US/boot_camp_install-setup_10.8.pdf

To reinstall OS X Mountain Lion, follow these steps:

1. Hold Command, Option (Alt) and R keys while your computer is starting to start in OS X Recovery, and open Disk Utility.

2. Select the hard drive at the top of the sidebar, go to Erase tab and erase the whole hard drive. Make sure that "Mac OS Extended (Journaled)" is selected next to "Format".

3. Close Disk Utility and reinstall OS X.

4. After reinstalling OS X, follow the steps of the site above to install Windows 7 on the MacBook Air properly

Follow the steps of my last reply

Internet Recovery downloads Recovery HD from Apple, so you will be able to reinstall OS X. Note that Internet Recovery and Recovery HD downloads OS X from the App Store, so you don't need OS X installed on the hard drive to reinstall it

From my second reply:

To reinstall OS X Mountain Lion, follow these steps:

1. Hold Command, Option (Alt) and R keys while your computer is starting to start in OS X Recovery, and open Disk Utility.

2. Select the hard drive at the top of the sidebar, go to Erase tab and erase the whole hard drive. Make sure that "Mac OS Extended (Journaled)" is selected next to "Format".

If you don't understand something, just tell me and I will try to clear your doubt

When you hold Command, Option (Alt) and R keys while your Mac is starting, your Mac will start automatically in Internet Recovery. This mode will download a recovery software from Apple, so you will be able to reinstall OS X without having it installed. If you want more information about that, see > http://support.apple.com/kb/HT4718

That's good. Choose your Wi-Fi network, and Recovery will start being downloaded

When you purchase OS X, you will be able to download as many times as you want for free. You won't have to pay to reinstall OS X Mountain Lion
