Q: Macbook Pro boots to old, deleted linux partition.

Did you use Bootcamp utility to create and later delete this troublesome partition?

If not, perhaps you could use Disk Utility (in OS X Utilities, via Recovery) to address it.

Or maybe it's time for a complete re-install of the OS X on a reformatted hard drive.

And remember to restore the Recovery partition.

Have you opened Startup Disk preferences and set your startup disk to your OS X volume? See if that works. If it doesn't, then it means your Linux installation has installed its own bootloader which you did not remove.

You need to repartition the drive back to a single OS X volume then reinstall OS X.

Clean Install of El Capitan or Yosemite on a Newly Formatted Disk

 

1. Restart the computer. Immediately after the chime hold down the Command-Option-R keys until a globe appears.
2. The Utility Menu will appear in from 5-20 minutes. Be patient.
3. Select Disk Utility and click on the Continue button.
4. When Disk Utility loads select the drive (usually, the out-dented entry) from the side list.
5. Click on the Partition tab in Disk Utility's main window. A panel will drop down.
6. Set the partition scheme to GUID.
7. Set the Format type to Mac OS Extended (Journaled.)
8. Click on the Apply button, then click on the Done button when it activates.
9. Quit Disk Utility and return to the Utility Menu.
10. Select Reinstall OS X and click on the Continue button.

Hi there,

Try this.  Turn off your computer, right when the chime sounds of mac or the screen turns on click and hold the option key. Then when you get to the boot manager screen click "Macintosh HD" or whatever your OS X boot drive is.

Let me know how it works out
