Hello guys, ive tried doing a search and i cant find anything so here i go. I booted up into Windows to work on some 3ds Max stuff, i finished and then rebooted into OS X. But when it restarted to reboot into OS X there was three chimes (the bong) and then it booted into OS X. Now everything i can see is fine and i just wanna know if i need to worry about this problem? I have a 24" iMac (early 2007 model) C2D. Any help would be great. Thanks.
