While I was installing Vista I got a message that said: "The drive failed verification and could not complete the task. Please repair your disk with Disk Utility". I went to disk utility and clicked repair permissions, and verify disk. Repair disk was faded, but when I did verify disk I got this message: "Disk Utility stopped verifying Macintosh HD because the following error was encountered: The underlying task reported failure on exit". It also showed a couple of errors. I heard that the way to fix this was to reinstall Mac OS X, but I don't have a OS X install disk. Also, if I did get an install disk would it destroy all the files I have already?
Got a tip for us?

Most likely you don't need to reinstall the OS. Why don't you have the OSX discs though? They include a version of Disk Utility that can repair your disk. You can't repair the disk you're booted from, which is why the option is greyed out. However, even though you don't have the OSX discs, you can bypass booting from the system, load into Single User Mode and run fsck. Keep running it 'til it makes no repairs. 
Well, the link I posted includes a section about Single User Mode and how to get there. Most likely you won't lose data loss unless something is really wrong. However, always keep everything backed up. Good luck mate.
