hi this is a continuation of this post: i forgot to mention that i accidentally changed the owner of the entire '/' directory to myuser. So i followed the help provided by both the answers and i managed to change the permissions of the entire '/' directory back to root... my permissions look like this:
owner: root (Create and delete files)
group: root (Access files)
others: (Access files)
but when i boot Ubuntu (i am currently in the same comp. but in windows) i get an error saying: The system is running in low-graphics mode
Your screen, graphics cards, and input device settings could not be detected correctly. You will need to configure these yourself.
when i click: run in low graphics mode this time, some console environment boots up but no sign of the original OS.
