If i understand you right you have chosen to use the entire disk when you install
If so, everything on that disk is supposed to disappear......
This assumption is based on that you write

I put in the CD had it go to the "select an option" page I selected the top one

and that you mean the partitioning page
If my memory serves me right the top option is "Use the entire disk" (haven't got the time to boot the live cd and check)

Supergrub can fix the mbr "the Windows way" It's a very small download from a very crappy home page, but a good product
