I have written in detailed about creating bootable Windows 10 USB on Linux. Thankfully, a handy open source tool called Ventoy helps a lot in this case. If you only have a Linux system, creating a bootable Windows USB could be tricky. If you have access to a Windows system, you can follow the instructions on the Microsoft website to create a bootable Windows media. How do you make a backup? The simplest method is to have an external USB or SSD disk and copy files from Documents, Music, Pictures and other folders where you have kept your files. In the worst case, if things go wrong, you can install either of Windows or Linux and copy the data back on your system. Having a back up on an external disk will give you a safety net. You are going to play with disk partitions and boot settings.

A way to back up your important data on an external disk (optional yet recommended).

Internet connection is needed for creating the bootable Windows and live Linux disk.

A computer with UEFI boot and only Ubuntu Linux installed on it.

A bootable Windows 10 USB stick (USB key, Pen Drive) of at least 8 GB in size.

Here’s all the stuff you need to carry out the procedure safely and easily: In theory, the same steps should be applicable to most Linux distributions, if not all. I tested this tutorial on an Ubuntu system with UEFI and GPT partitioning scheme.

What if you have a system that has only Linux installed on it and you want to install Windows alongside Linux in dual boot mode? On the boot, you select whether you want to use Windows or Linux. When it comes to dual boot, the general idea is that you have a system preinstalled with Windows and then you install Linux alongside Windows.
