Question: Trying to create a [Hiren's BootCD](http://www.hiren.info/pages/bootcd) on a USB. Not needing anything else such as a dual boot of Ubuntu and Haren or Window's and Haren. All the programs that I can find to complete this either end up directing me on how to create a Ubuntu boot on a usb, or how to do it on Windows. But since it is my Windows computer that I'm trying to fix I need an alternative. Please Help?

Answer: 
None of the below methods will work.
Although you will get a bootable USB, it doesn't chainload anything out of the Grub Menu. This is especially true for the 'revised' edition of Hiren's Boot CD (the one with the mini-version of Windows XP)

Here is the correct procedure:

Insert your USB drive into your PC and start Ubuntu's partition Manager. Format the drive to FAT32, primairy partition and give a nice label.
While you are at it, note the device's mount location (for example /dev/sdb)

When it is done, close the partition manager and start a terminal.

```
sudo grub-install /dev/device location

```

Where 'device location' is the location of your USB drive you noted earlier.

Now place the Hirens Boot CD iso-file in a new folder.
Right-click the file and choose 'extract here'
When it is done, delete the iso file and copy all the rest of the content to the root your USB drive.

There should be 1 folder called HBCD on the drive now, and 4 small other files.
Now open the folder called HBCD and copy the files 'grldr' and 'menu.lst' to the root of the drive. Be sure to **copy** them, **do not cut**.

That is it, you're done.
It should work now as a bootable USB drive aswel as a tool you can use inside a MS Windows environment.
You can make a bootable USB on Ubuntu from any (bootable) .ISO image using `dd` command:

```
dd if=./someisofile.iso of=/dev/sdb

```

however, I'd like to warn you that `dd` is a very dangerous command and you should only proceed if you fully understand the meaning of its parameters, in particular, the `of` one. 

If you google for something like "dd iso usb", you'll fins quite a few tutorials, for example [this one from Fedora](http://fedoraproject.org/wiki/How_to_create_and_use_Live_USB#Using_dd_for_a_direct_copy), [this one from Linux Mint](http://community.linuxmint.com/tutorial/view/744), or [this one from ArchLinux](https://wiki.archlinux.org/index.php/USB_Installation_Media)
