Not sure I understand your problem if this statement is correct then mint should boot.
Lets try to clarify some things:
Is your laptop new?
What operating system was on your laptop before you tried to install Mint 14?
Are you trying to dual boot with windows or do you just want Mint 14 on the laptop?
During the Mint install did you choose custom partitioning or did you let Mint do it automatically?
Also from your mint live cd run gparted and make a note of all the partitions and the file types and post back the information. Or upload a screenshot of gparted if possible.
