Long ago, I created a Windows partition for bootcamp. Now that I no longer need it, I erased the partition using disk utility. Although I erased the partition, and repartition Macintosh HD, the bootcamp partition still shows up as a hard drive on startup. If I try to boot from it, windows tells me I need to repair the computer. How is this possible, if I deleted the partition and repartition Macintosh HD. I'm currently running 10.8.4 with all updates, and using a June 2013 Macbook Air 11 in.
