Hello guys! Thanks for reading. (I apologize in advance for the grammar, I'm not English native)

I'm a mac noob willing to learn. I screwed up a couple of days ago exploring my new Macbook (wich i purchased to learn MacOS).

Little description:
What I've done: I changed the permission to the Macintosh HD doing the following:

1. Macintosh HD icon > Get Info
2. I remember to saw a permission options which i unlocked for editing, and changed the permission for the user "Everyone" to None access or smthing
3. I think the other users where Admin & my personal user, those where allowed to read and write i think (I don't remember quite well but i did not changed those users)

After that my Mac didn't start. It keeps loading after the grey apple screen finish. It keeps looping trying to login my user session i think.

I have a some code logs i got from the screen when trying Command+S. Hope it helps:

/System/Library/CoreServices/loginwindow.app/Contents/MacOS/loginwindow[xxxx]: Login Window Application Started
mds[31]: (Error) Import: importer:0x84a200 Importer start failed for -2 (kr:268435459 (ipc/send) invalid destination port)
com.apple.launchd[1] (com.apple.mDNSResponder[xxxx]): posix_spawnp(~/usr/sbin/mDNSResponder", ...): No such file or directory
com.apple.launchd[1] (com.apple.usbmuxd[xxxx]): posix_spawnp(~/System/Library/PrivateFrameworks/MobileDevice.framework/Versions/R/Resources/usbmuxd", ...): No such file or directory

I've read a couple of solutions on how to change the permissions but the thing is that i don't want to screwed up again since i have some data inside that i don't want to miss.

I hope that someone can help me. If some more details are needed please let me know. Thank you in advance!!

Note: I don't have the discs since I bought it from an owner. Mac is running Leopard and tried to boot from a Tiger DVD that was lend to me but didn't boot :(. Any ideas in how to change the permission or some solutions :(

If you have access to another Mac with Firewire, and if yours has Firewire too:

If you are able to see it on the other Mac, change the permissions back.
