I am brand new to the mac world so I am not exactly sure what is going on. I just decided to let my macbook check for updates. It found 3 things it needed to update. After updating it said that I needed to restart or shutdown my computer in order for the updates to take effect. I choose to restart it. When it restarted all I get is a bluish white screen (before you even get to log into the mac osx system) whith a folder that has question mark in it! I dont even get the chance to put my password in to get into the computer. So basically I cannot even use my computer. I am typing this on my windows based desktop right now. What is going on? I am really hoping that I did not lose all my info or anything. I have had my mac for just a couple weeks and I just recently migrated all my docs from my windows based pc to my macbook. Please any help would be greatly appreciated.
