MBP thinks it still has a Win partition

[charlien]

Recently I installed a new hard drive in my MBP and divided it into two partitions - Win 7 and OSX with Win 7 being the default boot partition. I changed my mind and reinstalled my old drive. Now when I turn it on I get a "no boot drive" Windows error unless I press the option key and then press enter on my OSX option (the only option). I assume somewhere in my MBP it still thinks I have OSX and Win 7. Can someone tell me what I need to reset to clear it?

Thanks in advance

When you boot into OS X, open System Preferences, go to Startup Disk, and select on the Mac partition. It should work.

Thanks for the quick reply. That fixed it and it was pretty easy.

Anytime, glad it worked.
