Need Help! Not Booting Up

[peterjc01]

hey everyone, well being dumb today, I went to right click on the mac hd icon and clicked on get info. I clicked on Ownership and Permissions and for the "everyone" section I chose None. Everything was fine till after I tried to boot up my macbook again and it just goes to the blue screen and it tries to load but stays at the blue screen.

I tried resetting the pram and that didn't work. Next put in the mac osx cd and ran disk utility to repair the drive and still nothing. Any ideas? 🙁

Target disk mode...?

If you can boot up your Mac in target disk mode from another Mac, you may be able to see your hard drive and undo the permission problem by right-clicking the drive and changing the permission back... Good luck!
