Problem starting up MacBook after removing Windows partition

Hi, I'm having trouble starting Mac OS X after removing the Windows partition of Boot Camp.

I get a black screen that reads,

" no bootable device -- insert boot disk and press "

I can load Mac OS X if I press the Option key during startup, and select the Mac hard drive.

How do I load up the Mac OS X system without having to do it manually? I'm a brand new newbie with Macs. Thanks a lot !

Try this:

Boot up the Mad in OS X by holding down the option key and selecting the Mac Hard Drive.

Once booted, go to System preferences > Startup Disk and select the Mac HD that has OS X on it.

Close the window and see it that makes any difference for you at the next reboot
