    I installed windows on my imac and later deleted the partition. But now when i boot it says something like no bootable devices in like this black screen. I know to hold the option key to select OSX but i need to know how to make it boot automatically. Any help?

    When your booted into os x, go into system preferences find start up disk then click on the Macintosh HD icon ( it will tell you what OS is on the drive ) then click restart. That will set the boot order.

    Or do a PRAM reset that will also clear it and default the OS X partition to be the start up one.
