Currently running Snow Leopard on 13" 2011 MBP. Previously I had a BootCamp partition with Win7. I upgraded the RAM and created VM's of Win7 using Virtual Box. Last night I went ahead and deleted the Windows partition using BootCamp (the remove partition option). After I did that, if I reboot the computer/cold start it I will get stuck on the "grey" screen and the computer will not continue to boot. If I start the computer and hold down the "options" key (like I would to choose with partition I wanted to boot in to - Windows or OSX) I will then get the "choice" to boot in to OSX/Mac partition. Is there something I need to do so I won't have to choose which partition to boot in to (which is kind of crazy since there is now only one). Thanks!
