Hey guys, i got an iMac 27' and i wanna format it. Is it almost the same as windows? I mean, i just back up my files and then put the installation disc that came with the computer and then install it again? Thanks for the support.

Part One: Erasing the hard drive

1.Turn on the computer.
2.Insert the Mac OS X Install DVD into the optical drive, or insert the MacBook Air Software Reinstall Drive into the USB port.
3.Press and hold the "C" key while the computer starts up. The computer will start up using the Install media. Alternatively, press and hold the Option key at startup to select the volume containing the installer.
4.If your are using a wireless mouse, a mouse icon should appear asking you to turn the mouse on so that the computer can discover it.
5.Select a language, then press the right arrow key.
6.Click the Utilities menu, the choose Disk Utility.
7.Select a volume to erase (usually called Macintosh HD).
8.Click the Erase tab.
9.Click Erase... Important: This step will completely erase your hard drive. If you have installed Microsoft Windows using Boot Camp, or have multiple partitions, this procedure will erase the partition you select.
10.A dialog box appears asking if you want to erase the partition: click Erase.
11.After the partition is erased, choose Quit Disk Utility from the Disk Utility menu.

Part Two: Installing the operating system

1.When the Mac OS X Snow Leopard Installer screen appears, click Continue.
2.When the license agreement appears, click Agree.
3.Select the disk you erased. It should now be highlighted with a green arrow.
4.Click Install. A status bar appears on the bottom of the screen while Mac OS X installs.
5.An Additional Information screen appears, advising you that you operating system has been installed. Click Continue.
6.An Install Succeeded screen appears. Click Restart.

Hope I helped! :)

fyi do not use the 'case sensitive' when you reformat, it doesn't help any, and usually only causes problems
