Hello
if you can not use your optical drive , try use fsck comand line
boot in single user mode first by CMD and S key hold togather at start up
apple KB article http://support.apple.com/kb/HT1492
fsck -fy   - Check the boot volume's file system, and repair if necessary (the "-y" means "Yes, go ahead and fix any problems you find"). Always do this first. Note that this may not be able to fix all problems in a single pass, so if it finds and fixes anything (it'll print "***** FILE SYSTEM WAS MODIFIED *****"), run it again, and keep running it until it comes back with something like "The volume Macintosh HD appears to be ok."
