I'm interested in learning Linux and have watched plenty of videos, but I still want hands-on experience. I play games that use anti-cheat systems Linux may not support, so I'm considering dual-booting Windows and Linux. How are files and partitions handled in a dual-boot setup? Could saving Linux files on a drive that also contains Windows data damage or interfere with anything?

A dual-boot setup normally gives each operating system its own partition and filesystem. Linux can generally read and write Windows’ NTFS partitions, while Windows usually cannot read Linux filesystems such as ext4 without extra software. Simply accessing Windows files from Linux will not normally corrupt them, but it’s still wise to keep backups and avoid modifying system folders. Also, disable Windows Fast Startup before sharing NTFS partitions, since it can leave them in an unsafe hibernated state.
If your goal is only to explore Linux, try it in a virtual machine first. You can install different distributions, customize them, install software, and save changes just like on a normal installation. The main limitations are reduced performance and weaker graphics support, so a VM is not ideal for testing gaming or hardware-intensive features.
Using a separate drive for Linux is the safest and least confusing option, especially if you have one available. It reduces the chance of accidentally changing Windows partitions and makes reinstalling either operating system easier. Installing both on one drive is common and can work fine, but pay close attention during partitioning and make a backup first.
Linux Mint is often a comfortable starting point for someone coming from Windows. You can also boot a Linux installer from a USB drive and use its live environment without installing anything. That lets you check whether your Wi-Fi, graphics, sound, and other hardware work before committing to a dual-boot setup.

That sounds useful for learning and customization. I’d probably still want a proper installation later if I decide to use Linux regularly.
