Hey..
I urgently need some help here 🙁
I used my macbook as always today, and suddenly the screen which tells me to hold down the power button to restart the computer appeared (this one: http://i44.tinypic.com/2n1gvf4.jpg )
When it started booting again, it started with the apple logo at the bootscreen and suddenly changed to a stop sign ( like this: http://psglib.files.wordpress.com/2007/06/w_no-parking.jpg but without the P inside 😀 )

Then it started booting windows instead of mac osX.. it boots up fine.
Then I restarted again, holding down the "alt" key and 2 partitions appeared. One named EFI boot (The one named Macintosh HD) and the windows partition.

When i choose EFI boot, it just starts booting windows.. 🙁

Help? 🙁
