Okay, you may want to print this.

  1. Make the live USB. (sounds like you already did this part)
  2. Put the USB stick into your computer, then reboot it.
  3. During the boot-up, while the BIOS is loading (usually it will show the logo of the company who made your computer,) spam all the F# keys (usually it's F12) so that it will ask you where you want to boot from. (If it enters a settings menu, reboot and try again. You want to get into the "boot select" menu or something like that.)
  4. Pick "USB" (NOTE: if this option isn't available, you may have to go with a CD...)
  5. If you've done everything correctly, it will display this logo that looks like "[stick figure]
  6. Follow the on-screen instructions to install Ubuntu!

If you need any more help, just ask me in a comment. (Use another computer for that.) I will be glad to provide assistance.

Windows:

Mac Os X:

1 Download Ubuntu Desktop

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

3 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.

4 Run diskutil list to get the current list of devices.

5 Insert your flash media.

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

7 Run diskutil unmountDisk /dev/diskN (replace N with the disk number from the last command; in the previous example, N would be 2).

8 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.imgor ./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 9 Run diskutil eject /dev/diskN and remove your flash media when the command completes.

10 Restart your Mac and press alt/option key while the Mac is restarting to choose the USB stick.

1 Insert a USB stick with at least 2GB of free space.

2 Open the dash and search for Startup Disk Creator.

4 Click 'Other' to choose the downloaded ISO file.

5 Select the file and click 'Open'.

6 Select the USB stick in the bottom box and click 'Make Startup Disk'.

7 That's it! When the process completes, you'll be ready to restart your computer and begin installing Ubuntu.

If your computer doesn’t automatically bring the boot menu, you might need to press the F12 key(or Esc Key) to bring up the boot menu, but be careful not to hold it down - that can cause an error message.

1 Turn on your computer with the usb already pluged in

2 Then quickly press esc or F12 to bring the boot menu.

3 Choose the Usb option and then you do the waint part.

4 Then it's easy just configurate the ubuntu and you're ready.
