I would start as if you were toilet training a puppy... lots of trips outside, lots of praise (and maybe even a yummy treat) for performing outside, and ignore any puddles you may find inside. If you see her sniffing around as if looking for a spot to wee, just take her outside. You might want to introduce a command for going to the toilet ("be clean" "wee-wees" or whatever suits you!) - just say this everytime she performs and in time you will be able to prompt her to go the loo by using this command.
From what you say I doubt she has ever had even the most basic toilet training, so it will be a case of starting from the very beginning. She will not know that laminate is easier to clean than carpet (and to a dog carpet seems to "clean" better as it absorbs the wee!!!
Given her history, you will need to be very gentle and patient with her, as it will all be a big change for her - well done for giving her the home she deserves!!
Oh, and pictures are a must here!!!
