Ok so last night i was trying to set permissions to some folders in my File System, since apparently im not an admin on my own computer. And now everything got messed up today and i don't know what to do..
- I lost my internet, the icon is not showing in the taskbar anymore.
- I lost my sound, there is no sound devices listed when i go into the sound menu.
- I can not log into root anymore, it gives me "sudo: must be setuid root"
- I can not plug anything in anymore, it will not recognize flash drives or external hard drives.
- It gives me a Internal Error message everytime i log in
- It doesn't let me log into the Grub screen anymore on boot up.
What did i do? I have a lot of files on here i wish to put on a flash drive but it won't recognize it.

Sounds as if you changed the ownership and / or permissions of system files.
You can search ~/.bash_history for the commands you ran, and if you post them here perhaps they are easily reversed.
Look for commands such as
chown
orchmod
, if they were run with the -R (recursive) option, easier to re-install. If, however, you changed only a few files or directories, recovery is possible.Often though you will have to re-install as manually fixing permissions is time consuming and imperfect.
In the future see: ubuntu sudo page
Normally you use
sudo
or for graphical applicationsgksu
to perform system administration or edit system files.Example:
