As I remember part of the problem we were having offering advice was the way your PC was booting into an operating system. Either Grub should have cropped up giving you the choice of Windows or Linux or it should have opened Mint in the usual way, the options you listed aren't anything I've seen after numerous linux installs.
Whatever, I don't see the Linksys Dongle as being an issue, though general rule of thumb when doing a Linux install is have a live wired internet connection to enable the PC to download any additional drivers that may be required. If you have a functioning Wi Fi connection in Linux the drivers are OK.
What shows up on Menu/Accessories/disks ? it should show everything on your hard drive, does the drive capacity listed match the actual size. As I said before if the Windows OS isn't on a separate partition which should show up, it has probably been overwritten. If this is the case then the short answer to your question " where is windows now and how do i get to it ." is it's under the Linux install and you can't, you'll need a new copy on a disk.
All this with the obvious proviso that I can't see your screen so I'm guessing.
