Kali Install Error (SOLVED)

Hi, I am encountering issues while installing Kali 1.1.0a on Virtualbox 5.0.12 on my Mac Book Pro. I have tried re-downloading the .iso file multiple times, but alas the problem persisted.

In case it is of importance, I downloaded the file named:
"kali-linux-1.1.0a-amd64.torrent"

located here

I get a Bad Archive Mirror error. I tried every mirror available on the list provided on the install (none worker). I did some research and learned that I could potentially fix this later; after the install, and so I trekked on.

Unfortunately, I was then met with a Grub Installation Failed Error. I honestly have absolutely no idea what to do, since at one point in time I had Kali working on a VM, but after reformatting my drive and trying to re-install a few months later, it simply isn't working.

Any help regarding this matter would be much appreciated!

P.S. Sorry for posting two questions within the span of only a day. I don't mean to be spammy, but directly after getting a answer to my other question:

Virtualbox Kali Bridged Connection Issue

I was immediately met with more problems, which even after hours of online research, still remain unsolved.

Thanks,
Draos
