How to create a boot pendrive in Ubuntu? [duplicate]

Solution 1:

Ubuntu comes with a Startup Disk Creator by default.

Press the Super key (usually left windows key) and in the serach box type startup and you will be provided with options including Startup Disk Creator which you should select.

This will provide you with the following window from which you can make your selection as to the iso you wish to use (the top selection) selecting Other... if the iso is not in your /Home/[user]/Downloads directory and then Make Startup Disk by selecting the already inserted USB pen drive in your PC.

Then click on Make Startup Disk when the routine will commence.

Note that if there is already something on the USB drive, it will be overwritten by the Startup Disk Creator and there is no need to perform any other tasks on the drive before proceeding.
