My PC was recently compromised, and after changing passwords, troubleshooting everything, and eventually factory-resetting the system, I'm still pretty anxious about it happening again. I'm considering Linux because I'm concerned about Windows security and privacy, but I'm not ready to give up Windows completely. Dual-booting seems like a way to learn Linux while keeping Windows available when I need it. How difficult and safe is dual-booting for a beginner? What are the main advantages and drawbacks compared with using Linux alone or running Windows in a virtual machine?

Before dual-booting, ask whether you actually need Windows. If you only use it occasionally, installing Linux as your main system and running a Windows virtual machine for specific applications can be more convenient. Shared folders make it easy to move files between them, although demanding software and some games may not work well in a VM.
If you do dual-boot, keep the setup simple: use one familiar Linux distribution, install it carefully, and make sure you understand which drive and partitions you are changing. A separate SSD for Linux can reduce the chance of accidentally altering your Windows installation. Set Linux as the default if that is where you expect to spend most of your time, while leaving Windows available for tasks that do not work elsewhere.
Dual-booting is a reasonable option if you genuinely need Windows for certain software or games. Linux and Windows run at full performance, unlike a virtual machine, which may have compatibility or performance problems—especially with games that use anti-cheat systems. The tradeoff is that you have to reboot to change systems, and updates or installation mistakes can occasionally cause boot issues. Keeping each operating system on its own drive and maintaining a full backup makes recovery much easier.
Linux can be a good learning project, but switching operating systems by itself will not prevent compromises. Security also depends on updates, strong unique passwords, multi-factor authentication, safe downloads, backups, and avoiding suspicious links or programs. Windows is not automatically insecure, and Linux is not automatically safe just because it is Linux. If you are new to it, start with a beginner-friendly distribution, test it from a USB drive or in a virtual machine, and keep your important data backed up.
That sounds closer to what I want. I mainly want to learn Linux gradually and eventually decide whether I can use it full-time, rather than making the security situation worse.
