There's quite of lot of knowledge needed to create a bootable USB stick manually from the command line. I've forgotten more than I can remember about that because nowadays I always cheat.
Do you want to know how to do this manually as a learning exercise or do you just want to get it done anyway you can?
Do you have a Windows machine available to you?
I see the media you are starting with is an iso and you can't just dd an iso image to a USB stick and expect it to boot.
My preference would be to put the iso file on a Windows platform and then download (free) a copy of Rufus. Tell Rufus that it's an iso file as input and it will do the whole thing for you.
If you don't have a Windows box take a look at Unetbootin. That will do the same thing on unix/Linux.
Of course, the bios of your machine that you want to boot from USB must support that and have that function enabled but I guess you already know that.
It depends what you want/need to learn about this but, as I say, I just cheat. Other members on here might be able to tell you how to do it manually but I can't remember all the details.

grml2iso
GRML2ISO(8) GRML2ISO(8)
NAME
grml2iso - create a multiboot grml ISO using grml2usb
SYNOPSIS
grml2iso -o <target.iso> <ISO[s]>
Important! The grml team does not take responsibility for loss of any data!
INTRODUCTION
grml2iso allows you to create a multiboot grml ISO. You can specify two or more grml ISOs and will get one single multiboot ISO as a
result. grml2iso requires and uses grml2usb for this task and installs grub2 as bootmanager on the multiboot ISO.
OPTIONS
grml2iso supports the environment variables GRML2USB and WRKDIR. GRML2USB specifies the path to the grml2usb script you'd like to use.
WRKDIR specifies the work directory for creating the filesystem. The work directory needs at least as much free disk space as the sum of
all specified ISOs.
-o <target.iso>
This option is mandatory and specifies where the resulting multiboot grml ISO should be placed. Note that (to avoid any possible data
loss) grml2iso will exit if the specified target.iso exists already.
-c <directory>
The content of the specified directory will be copied to the resulting multiboot grml ISO.
-b <boot params>
Use specified default bootoptions as default.
-f
Force the program to run and overwrite an existing iso image.
-r <boot param>
Remove specified boot parameter from existing command line. Could be specified multiple times.
-p <grml2usb param>
Execute grml2usb with the specified parameters. For a list of valid parameters have a look at the grml2usb webpage[1] or the grml2usb
manpage
-s <URI>
Generate a small iso file which downloads the squashfs file from the specified URI. Due to current limitations in busyboxs wget and DNS
resolution, an URL can not contain a hostname but an IP only. This is useful if you want to boot systems which support booting iso
image from your local system. Besides the iso image this command also copies the squashfs file to the output directory.
USAGE EXAMPLES
# grml2iso -o /tmp/grml.iso grml_2009.05.iso grml64_2009.05.iso
Create multiboot ISO /tmp/grml.iso with grml_2009.05.iso and grml64_2009.05.iso.
# grml2iso -b 'lang=de ssh=passwd' -c /tmp/grml-content -o /srv/grml.iso /srv/grml/grml_2009.10.iso
Create a new iso with additional boot parameters and copy the content from /tmp/grml-content to the generated iso image.
# grml2iso -r quiet -r vga=791 -o /srv/grml.iso /srv/grml-small_2009.10.iso
Create a new iso and remove existing boot parameters quiet and vga=791.
# GRML2USB=/srv/git/grml2usb grml2iso -o /srv/grml.iso /srv/grml/grml_2009.05.iso /srv/grml/grml64-medium_2009.05.iso
Create multiboot ISO /srv/grml.iso with grml_2009.05.iso and grml64-medium_2009.05.iso using /srv/git/grml2usb as grml2usb script.
# WRKDIR=/mnt/test/grml-tmp grml2iso -o /mnt/test/grml.iso grml_2009.05.iso grml64_2009.05.iso
Use /mnt/test/grml-tmp as working directory for creating the multiboot ISO /mnt/test/grml.iso with grml_2009.05.iso and grml64_2009.05.iso.
# grml2iso -p --skip-addons -o /srv/grml.iso /srv/grml-small_2009.10.iso /srv/grml64-small_2009.10.iso
Don't copy the addons from the specified iso images
