How to get rid of Linux for an absolute Newbie

My husband installed Lubuntu on my computer and erased my Windows. I hate it, I want to delete Linux and install Windows again. My husband has a burned install CD that he used to put Linux on my comp and I have the original acer windows upgrade cd my laptop came with. I have read half a dozen tutorials on removing linux and just cant access the screens Im told to access.

I put in the burned linux cd and restart the comp. I get the brief acer start up screen (with options to press f2 to enter setup or f12 to change boot order... I tried both of those but couldnt figure out what to do in those screens.) When I let that screen pass I get the linux startup options screen, there are various options like starting up from the local hard disk, etc. None of these options mention the command prompt or starting up from the boot disk... I dont know how to even get to the command prompt to follow the directions I searched up here:

What am I doing wrong? What do I need to do (from the moment I restart the comp absolute beginning) to get rid of this god-awful thing?
