I'm dual-booting Linux Mint and Windows, with each operating system installed on its own drive. Linux Mint is my main environment for important files, while Windows is mainly for gaming, including games obtained from unofficial sources. How much protection does the separate-drive setup provide, and are there extra precautions I should take to reduce the risk of malware affecting my Linux installation or personal data?

Windows updates can occasionally change the default boot entry or make the system start through Windows Boot Manager instead of GRUB. That usually affects boot selection rather than damaging Linux, and you can generally restore the preferred boot entry from firmware settings or a Linux live USB. Keep a live USB and backups available just in case.
If your main reason is gaming, Windows may be convenient, but ordinary downloading and torrent clients also work on Linux. Regardless of operating system, keep personal documents off the gaming installation, don’t share sensitive folders between systems, and maintain offline backups. There’s no setup that guarantees complete safety.
The bigger risk is the software you run in Windows, not dual-booting itself. Treat unofficial game installers as potentially unsafe: scan files, keep Windows and its security tools updated, use a standard user account, and don’t disable protections just to make an installer work. A virtual machine or a separate computer gives stronger isolation, though it may not be ideal for gaming.
