Redirect to Main/Home Page

Had our website revised and now I’ve got a ton of 404s that I need to redirect. I understand how redirect works and have been able to redirect many of the old links, but here’s my problem:

My 404s show like this: /about-us/ or /media/press-releases/
and I understand that the first part of the url (www.myfakesite.com) is understood. The problem happens when I want to redirect them to my home page as I’m not sure what to put in the redirect box. If I type just the forward slash / I get an error. (Is this called a loop?) And if I type the full URL as: http://www.myfakesite.com/
then it tries to redirect to http://www.myfakesite.com/www.myfakesite.com and creates a new 404 error. And I don’t have a page named Home so I can’t redirect as /home. How are other people doing this?

I’m not very schooled in code and I am learning about all this as I go along, so it would be most helpful if someone could please explain in terms that this newbie can understand and learn. 🙂 Thanks so much!
