Arduino Mega 2560 not recognised in COM1

I just recently bought a new Arduino Mega 2560, im completely new to these boards, so im going to need a fair bit of patience from you guys in helping me with my problem. Im following the "getting started" steps to set up my board, im currently stuck on installing the device drivers, it says "Look under Ports (COM & LPT). You should see an open port named "Arduino UNO (COMxx)", isntead i can only see it in "Other devices", and even when i try and update and install the drivers from other devices, when i go to the directory of the drivers it wont work. Im asking you guys to help me get this sorted, i want it to show up in COM1, and help me individually select the file to update the drivers.

Kind regards,

Jacob

Which OS are you using?
