Update error - cdrom?

[whirlygirl]

Hi.  I just installed linux lite on an old HP. I installed from a dvd I burned to on the same computer.  When I try to update I get the following error.  I am a complete novice. I tried reading other threads, but they didn't seem to pertain, so I am sorry if this is a duplicate.

Hmm, it doesn't look 'installed' it looks like you are running it Live. Also, make sure DVD is NOT in drive when doing Updates.
