I tried installing Windows with bootcamp and gave up (long story). I went into disk utility and removed the partition that bootcamp created. The problem, however, is that when I restart my MBA, it goes to a black screen saying that there's no bootable drive. If I hold option, I can select OSX or Recovery drive. Selecting OSX brings me to my desktop and everything is fine. I simply want to get rid of the need to hold option. Any advice?
