You fail to explain that this command only works for root.

thank you, had not dont that before.

unable to mount iso file using command mentioned above as each time there is a extracted directory made in test folder

it also works without "-t iso9660" (mount -o loop file.iso /mnt/test)... When I tried, your command doesn't work at all...

your iso image file system was another ;)

works fine, how would you unmount

umount /mnt/test

eh... it says "mount: mount point /mnt/[name] does not exist"
wat do i do?

you need to create the mount point first, i.e. "mkdir /mnt/test"

lawrence@Inf1n1ty:~$ su
Password:
su: Authentication failure
lawrence@Inf1n1ty:~$ sudo -i
root@Inf1n1ty:~# mkdir -p /mnt/disk
root@Inf1n1ty:~# mount -o loop BF1942_1.iso /mnt/disk
BF1942_1.iso: No such file or directory
root@Inf1n1ty:~#

so when i log into root, cannot as it is locked, so use sudo to gain root privileges, Then when I go to mount the image it doesn't find it.
Is there a certain location that I need to place the iso in question?

what is the path to BF1942_1.iso relative to your current directory?

Should something like

mkdir -p /mnt/disk
mount -o loop /dev/USB/BF1942_1.iso /mnt/disk
... Make any sense?

lawrence - you arent specifying a path for your BF1942_1.iso file.
try
mkdir /mnt/foo
mount -o loop /dir/path/filename.iso /mnt/foo
that should do the trick

Your recipe seems like not working. I have given the command:-

mount -o loop -t iso9660 rld-dmc4.iso /media/Entertainment/Game/Devil\ May\ Cry\ 4\ Image/

And I got the o/p:-

rld-dmc4.iso: No such file or directory
