I am looking at this: http://www.ubuntu.com/download/help/create-a-usb-stick-on-ubuntu

I need to create a boot disk to test Ubuntu to make sure it will run on a PC (Compaq Mini CQ10-120LA) I was given. I can create the boot disk off of a Mac (in English) or Windows (but Windows is in Spanish and foreign to me).

Questions:

  1. What format do I choose for the USB stick? (I wish the instructions stated this).

  2. What is Dash? (Will I know when I run the installer?)

  3. Can I do this from a Mac or Windows computer? Or only from Ubuntu?

The instruction on that page is for existing Ubuntu users. You can't do the same from Windows.

If you want to try Ubuntu for the first time, (No Ubuntu installed) you need to use a Windows tool to make your USB disk bootable with Ubuntu. See this section of the help page. It is for Windows users. If you are a MAC user, you should visit this page

1) What format do I choose for the USB stick?

Assuming you are referring the filesystem type, I suggest using Fat or Fat32 filesystem. The Windows tool automatically uses this format.

2) What is Dash? (Will I know when I run the installer?)

Dash is a modern and visually appealing replacement of traditional menu system. It is included in Unity. You can see this in action, if you "Try Ubuntu" before installation using the Live CD/USB.

3) Can I do this from a Mac or Windows computer? Or only from Ubuntu?

Assuming you are referring to make a bootable USB, You can do this from Mac or Windows. You don't need to have Ubuntu for trying Ubuntu. This doesn't make good sense.

Hope this answer will help.

Windows

The instructions for preparing an Ubuntu live USB on Windows are found at the official Ubuntu How to create a bootable USB stick... webpage (see the step-by-step instructions below). The USB flash drive that you use to make an Ubuntu live USB must be 2GB or larger. For Ubuntu 18.04 and later the USB flash drive should be 4GB or larger.

  1. Open Rufus and select your USB stick in the Device dropdown menu.

    enter image description here

  2. Click the CD-ROM icon next to the FreeDOS dropdown menu, then find your downloaded Ubuntu ISO and click Open and then Start.

    enter image description here

  3. Click Yes when it asks to download Syslinux software.

    enter image description here

  4. Click OK to write in ISO Image mode.

    enter image description here

  5. Confirm that your USB stick is selected and then click OK to continue. It is very important to verify that the device that you are installing the Ubuntu live USB to is indeed your flash drive, so that you don't overwrite any of your system or personal files which may make your operating system unbootable.

    enter image description here

  6. When it is finished, just restart your computer and start using Ubuntu, or you can install Ubuntu.

    enter image description here

In order to enable your computer to boot from the USB flash drive, you must enter your BIOS/UEFI setup utility by pressing one of these keys: Delete, F2 or F10 as soon as the motherboard splash screen appears when the computer is booting. In the BIOS/UEFI menu, you need to change the boot order so that the USB flash drive, which is usually called USB-HDD in newer computers, is the first entry in the boot sequence, and then save your new settings and exit the setup utility.

Mac

This procedure requires that you create an .img file from the .iso file you download. It will also change the filesystem that is on the USB stick to make it bootable, so backup all data before continuing.

  1. Download Ubuntu Desktop

  2. Open the Terminal (in /Applications/Utilities/ or query Terminal in Spotlight).

  3. Insert your USB flash media, which must be 2GB or larger. For Ubuntu 18.04 the USB flash drive should be 4GB or larger.

  4. Launch the Disk Utility app which is located in Applications -> Utilities. Booting Ubuntu from the USB drive

    • In the lefthand pane, click on the USB drive to select it.
    • Click the Partition tab.
    • Select 1 Partition from the dropdown menu.
    • Enter a name for the drive.
    • Change the Format to Mac OS Extended (Journaled).
    • Click the Options button.
    • Ensure that the GUID Partition Table radio button is selected and click OK.
    • Click Apply.
  5. Convert the .iso file to .img using the convert option of hdiutil e.g.,

    hdiutil convert -format UDRW -o ~/path/to/target.img ~/path/to/ubuntu.iso
    

    Note: OS X tends to put the .dmg ending on the output file automatically.

  6. Run:

    diskutil list
    

    to get the current list of devices.

  7. Run:

    diskutil list
    

    again and determine the device node assigned to your flash media (e.g. /dev/disk2).

  8. Run:

    diskutil unmountDisk /dev/diskN
    

    (replace N with the disk number from the last command; in the previous example, N would be 2).

  9. Execute:

    sudo dd if=/path/to/downloaded.img of=/dev/rdiskN bs=1m
    

    (replace /path/to/downloaded.img with the path where the image file is located; for example, ./ubuntu.img or ./ubuntu.dmg).

    • Using /dev/rdisk instead of /dev/disk may be faster
    • If you see the error dd: Invalid number '1m', you are using GNU dd. Use the same command but replace bs=1m with bs=1M
    • If you see the error dd: /dev/diskN: Resource busy, make sure the disk is not in use. Start the 'Disk Utility.app' and unmount (don't eject) the drive
  10. Run:

    diskutil eject /dev/diskN
    

    and remove your flash media when the command completes.


Booting Ubuntu on a Mac from the USB drive

The newly created Ubuntu live USB drive is now ready to be inserted into a Mac.

enter image description here
Booting Ubuntu from the USB drive

To test the Ubuntu live USB on a Mac:

  1. Insert the USB drive into an available USB port.
  2. Reboot or turn on the Mac.
  3. Immediately after the startup chime, press the Option key (sometimes marked Alt).
  4. Select the USB drive from which to boot by using the left and right arrow and Enter keys.
  5. If you can't see the USB drive in step 4, download rEFIt EFI Boot Menu and Toolkit to get a screen where you can choose from the available devices to boot from.

You don't need a USB bootable to test if Ubuntu works on your PC. You can use a live cd for that.

but if you want to learn how to make bootable USB check these links:
