How to Install Ubuntu 19 from USB & Dual Boot Alongside Windows 10

Ubuntu 19.04 Disco Dongo is out now. If you’ve been contemplating switching to Ubuntu, now is probably as good a time as any. You don’t even have to sacrifice anything. You can install Ubuntu from USB in dual boot alongside Windows 10. This gives you the advantage of being able to use a more familiar OS when you really need to get things done fast and easy while you’re still learning your way around a new OS.

Let’s see how to install Ubuntu in Dual Boot Alongside with Windows 10.

Why Should you Install Ubuntu?

Windows 10 has come a long way but it is still just that, Windows. It’s the most popular desktop OS and generations have grown up on it, so it will probably remain popular for a while. But Windows has a lot of annoyances, with one leg in the modern world and one in the 90s. Windows is clunky if I had to use one word for it. We’ve all been taught in school that it’s user-friendly but is it really? Something even as basic as installing and uninstalling apps takes so many clicks. Things are changing now with the Microsoft Store but like I said, one leg in the modern world and another in the 90s.

Ubuntu, on the other hand, feels like a more modern desktop. It’s the most beginner friendly Linux distribution or at least one of them. It is definitely the most popular which makes getting support for it on online forums much easier. Features like virtual desktops that Windows got quite recently have been present on Ubuntu and other Linux distros for quite some time. Microsoft’s implementation is also not very user-friendly, requiring at least two clicks or the use of keyboard shortcuts. It’s much easier on Ubuntu.

There are many similar little features that make Ubuntu a joy to use, compared to Windows. New users can feel a little lost since it’s a whole different OS. You’ll end up using the command line more often than you might want but as you get used to it you’ll realize it’s much easier than you thought. Besides, what have you got to lose since, in a dual boot set up, you get to keep Windows, all your files, and you can just get rid of Ubuntu anytime you want to.

  7. When you’re ready, click Shrink and wait for the process to finish.

You now have to boot your computer using the bootable USB you just created. Depending on the make and build of your computer, the way to boot it using a USB will be quite different. Even computers from the same manufacturer don’t follow one strict method. So you’ll need to check about the specific method for your computer online. In general, the steps involve booting into the BIOS settings, where you can enable booting from a USB and move USB at the top of the boot order.

On some laptops and PCs, you can simply get to the boot menu by pressing a key combination right before the manufacturer logo appears or right after it. And then you can choose to boot from USB from the boot menu.

    • Bob, thank you for the feedback. would you please explain it? We checked the stesp again and don’t see the requirement for EFI partition step.

    • Hi Suman, were you able to install Ubuntu? If yes, and you still don’t see the grub bootloader, you can try a boot repair and you will need your Ubuntu live boot flash drive for it. This happens sometimes, so nothing to worry about. Boot repair is a graphical tool and it will guide you with everything you need to do, while most of the things it will do for you.
