Question

I have IMac 10.7.5 Lion I use I forgot the password and I did a few fixes from web sites, which did not work and now I can not get the computer to reboot the gray screen comes on with the apple and if a shift+c, I get a load bar and it goes half way and stops, I can get into the black screen area with the hard drive info
I did the following:   mount -uw /    rm/var/db/.AppleSetupDone    shutdown/uses/us  reboot Ok I know I should not have, but now I need help to reboot and hopefully not lose everything on the desk top, Linda Markle

Answer 1

You did the wrong things. In the future it's a good idea to remember not to do something when you don't know what you are doing and what happens when you do it.
