The commonly known methods to create a bootable USB flash drive to install Ubuntu on a computer is by using Startup Disk Creator or using UNetBootin. However, if you try either of these methods with recent versions of Ubuntu, you get this error when you boot up the flash drive on a computer:

The most reliable solution I have found for this error is to create a bootable USB flash drive using Disk Image Writer.
It is simple to do this:
$ sudo apt gnome-disk-utility
Insert the USB flash drive you want to use as the installer medium.
In your file manager, right-click on the ISO file and choose to open with Disk Image Writer. If you do not get this option, an alternative method is to open Disks from your start menu or execute
gnome-disks at the shell. First click on the USB flash drive in the left column. Next click the menu in the top-right corner and choose to Restore disk image.
Pick the ISO file and choose to restore it to the USB flash drive. It might warn that the destination is larger than the ISO, that is OK. After it is done, you can remove the USB flash drive.
This USB flash drive can now be used to boot and install Ubuntu successfully on any computer.
Tried with: Ubuntu 15.10 and GNOME Disks 3.16.2
I made a startup USB flash drive for Ubuntu 15.04 using Startup Disk Creator as described here. I booted a computer using this flash drive and the boot process threw this error:
Missing parameter in configuration file. Keyword: path
gfxboot.c32: not a COM32R image
(This error happens even if the drive is created using UNetBootIn as described here. It happens with Ubuntu 14.10 too.)
help at the boot prompt. It will show a menu of options. Hit
Enter here and Ubuntu will boot up as it should have.
You need a startup disk or USB flash drive loaded with Ubuntu to install it on a new computer. Ubuntu can be downloaded as an ISO file. The Startup Disk Creator tool can be used to create such a startup disk from a ISO file.
Startup Disk Creator will be present on a Ubuntu computer. If by chance you do not have it, it can be installed easily:
$ sudo apt install usb-creator-gtk
- Download the Ubuntu (or any other) ISO file you need to make a startup disk from.
Insert the USB stick or drive that you want to use as the startup disk. Note that it needs to be in FAT or FAT32 format! (Otherwise Startup Disk Creator will not show this drive.)
Start the Startup Disk Creator from the Dash or
usb-creator-gtk from the shell.
Choose the source disk image (the downloaded ISO file) and the disk to use and click Make Startup Disk.
Once it is done, you can use this USB flash drive to install Ubuntu on other computers by booting from this drive! 😃
Note: An alternative to Startup Disk Creator is UNetBootIn, which can be used as described here. I have faced problems using it for making startup USB flash drives of Ubuntu 14.10.
Tried with: Startup Disk Creator 0.2.56 and Ubuntu 14.04
