Hi Everyone, I am new to the mac world....a have a little problem with my OSX. I have a p5vd2-mx mobo, intel 531 ht processor, 2 HDD - 1-sata and the 2-ide (on wich i installed osx), integrated video card s3g igp unichrome. My problem is that if i boot normaly i get the "forbidden sign". When i try with -v it says "still waiting for root device, but when i boot using -v -f all goes well. How can i make it boot in normal state ? I've tried to set my BIOS to ahci,raid,ide...etc, and all the possibile combinations, and still nothing. Please Help

Boot with -f as usually, then open a disk utility. Select the partition where the OS X is installed and click Repair disk permissions. Alternatively my try this via the terminal

sudo -s
chmod -R 755 /System/Library/Extensions
chown -R root:wheel /System/Library/Extensions
rm -Rf /System/Library/Extensions.mkext

Restart with -v flag.
