Is there a feasible way to essentially just download a .img file of an already working Ubuntu distribution that I can write directly to my hard drive?
Pretty much any default would work fine for me but i spend most of my time every couple months burning it to a thumb drive and then waiting for the installation to work/finish.
As Videonauth pointed out, a custom installer would be a better solution. You can even make an unattended one so that it just installs without asking a bunch of questions.
With that said, according to some instructions, you can create a custom
.img
file fairly easily, though it won't be geared toward the hardware on your machine and the partition and so on will be pretty small:.iso

There are ways to create your own custom installers and you should definitively look into this.
