Wrong fs type...failed to mount /dev/loop0

Hello everyone

Today I torrented the newest (February) version of the arch linux iso. I checked the checksum as well as the signature and both were correct.

I used the ISO with the dd command to make a bootable USB, and then plugged it into my thinkpad.

I disabled secure boot, and booted it. It was working until it gave me this:

mount: wrong fs type, bad option, bad superblock on /dev/loop0
             missing codepage or helper program, or other error

             In some cases useful info is found in syslog - try dmesg | tail or so.     

ERROR: Failed to mount '/dev/loop0'
             Falling back to interactive prompt
             You can try to fix the problem manually, log out when you are finished
             sh: can't access tty; job control turned off
[rootfs ]#

How should I fix this error?

It was working

What? What were you doing when the error appeared? Did you enter a command? What was the command?

I didn't enter a command. There was a small menu that asked me what I'd like to install, so I clicked on the first option, arch Linux x86-64, and then normal installation text populated the screen until suddenly the error occurred.

Please post the exact dd command you used to create the bootable USB stick.

Re: Wrong fs type...failed to mount /dev/loop0

For some reason I can't find the exact command on my terminal (I'm running Ubuntu)..maybe because I turned off my computer yesterday or something?

However, I believe the command I used was this:

dd bs=4M if=archlinux-2017.02.01-dual.iso of=/dev/sda

Should i have clarified the folder after the if=?

I tried to do exactly as installation guide said, but the terminal said 'invalid status flag progress', so I just left that part out.

EDIT:

Here is a link to the verification of the signature and checksum

If the verification of the signature and checksum are correct, does that mean that everything up to the download went correct?

EDIT:
I forgot to upload a pic of the SHA1 sum but that's also correct as well.

EDIT:
I re-mounted the ISO on a new USB drive, with the command

sudo dd bs=4M if=/home/albysix/Downloads/archlinux-2017.02.01-dual.iso of=/dev/sda && sync

However, when I try to unmount it, it says

"Failed to eject medium, one or more volumes are busy"

However, when I try to unmount it, ....

Why is it mounted? It should not be mounted when using dd on it.
