so i'm guessing you are trying to set up file sharing between the two laptops? the next step depends slightly on what you want to do exactly. it is not recommended to share a whole drive as it poses a security risk. you can do it but it's not a good practice. you can either create a folder to place everything you want to share in, use the shared documents folder or just share particular folders containing what you want.
either way, find the folder you want to share, right click on it and choose the sharing and security option (this might not be there until you activate file sharing though, in that case open the properties and switch to the sharing tab). the options there should be fairly self explanatory. after you've enabled the folders you want to share you may need to reboot as file sharing can be a bit finicky. you should then be able to find the shared folders from the other laptop in the "My Network Places" on each respective computer.
