A desktop operating system such as Windows 10 or Ubuntu can be installed on a computer from a USB device. A USB device is required because these operating systems are large and once installed, the files expand to take up more space.
Not all operating systems are large as not all operating systems are installed on a desktop system. There are smaller devices that run an operating system and do not always have a USB port.
For devices without a USB port, an SD card is used. However, to use an SD card, you must use the OS, or whatever app/software you want to use.
Flash SD card
To flash an SD card with an operating system image, you need the file you are going to flash and an SD card. SD cards are not always small, in fact, you can get them in very large storage configurations.
Make sure your SD card is as big as you need it to be.
- Download and install a free tool called Etcher.
- Download the image / OS/file that you have to shoot.
- Insert the SD card into your system.
- Open Etcher.
- Click Open File.
- Select the file you want to burn/flash.
- Click on the Select target button and select your SD chart.
- Click Flash.
- Wait for the process for completion. It will take time depending on the size of the file.
Flashing and booting
You should know that you can burn all types of images to an SD card but that does not necessarily mean that you can get a hold of it. It is up to you to ensure that the image you are burning can be booted on the SD card.
We mentioned that SD cards come in a large storage configuration which means, you get one that is big enough to burn Windows 10. You will be able to use Ether to do that however, Windows 10 is NOT a system that can be accessed from an SD card.
You need a USB driver if you want to boot or install Windows 10.
SD cards come in larger storage sizes but operating systems and devices are in no hurry to support them as bootable devices. SD card, because of its size, is best used on devices like Raspberry Pi. For devices that have a USB port, it is better to use it as it will be faster than an SD card.
