I've been interested in switching to Linux because I'd like to move away from Microsoft, try something different, and use an open-source operating system. Linux Mint seems like a beginner-friendly choice, but I'm not very tech-savvy and I'm worried about accidentally losing files or breaking my computer.
My computer currently has Windows installed on a single SSD. I know beginners are often advised to dual-boot, but buying another drive isn't ideal unless it's truly the safest option. Could I shrink the existing Windows partition and install Mint alongside it? I've read that Windows updates can sometimes interfere with GRUB, the bootloader used to choose between Windows and Linux, and that mistakes during partitioning could corrupt or erase data.
What would be the safest approach for someone inexperienced? Should I back up or clone the drive first, try Mint from a USB, use an old computer, install it beside Windows on the current SSD, or replace Windows entirely?

The most important thing is having a backup before changing partitions or boot settings. Ideally, make both a full drive image and a separate backup of your important files. Clonezilla can make an image, while Rescuezilla provides a more graphical interface. The image lets you restore the entire drive if something goes wrong, and the file backup makes it easy to retrieve individual documents.
You can install Mint beside Windows on one SSD by shrinking the Windows partition and selecting the option to install alongside the existing system. Mint will normally install GRUB so you can choose either operating system at startup. Windows updates can occasionally replace the bootloader, but that is usually repairable from a Linux live USB.
A separate drive is simpler and safer because you can leave the Windows installation untouched. An external USB SSD or an inexpensive internal drive can work, and you can select which one to boot using the computer’s boot menu. If installing to another internal drive, temporarily disconnecting the Windows drive during installation helps prevent accidentally selecting the wrong disk.
It’s also completely reasonable to back up your files and switch entirely to Mint instead of dual-booting. If you later decide it isn’t suitable, you can reinstall Windows from installation media. Linux does involve some learning and occasional reading, even with a beginner-friendly distribution, but you don’t need to be an expert before trying it. Start with a USB session or an old machine, keep reliable backups, and take each step slowly.
You don’t necessarily need another drive to dual-boot. Windows should be installed first, then you shrink its partition from within Windows, boot the Mint installer from a USB drive, and install Mint into the unallocated space. The installer will set up the boot menu automatically.
That said, don’t treat this as a backup-free experiment. Copy anything important elsewhere before starting, and make sure you understand which disk and partitions the installer is using. The biggest danger is selecting an erase-and-install option or proceeding without a backup, not Linux itself.
Before modifying your main computer, try Mint in a virtual machine, boot it from a USB stick, or install it on an older computer such as that 2012 MacBook you mentioned. This lets you get familiar with the desktop, applications, Wi-Fi, and basic settings without risking your Windows installation.
A live USB is great for checking whether your hardware works. It generally won’t save changes between sessions unless configured for persistence, but it’s an easy first step. Also prepare a Windows installation or recovery USB ahead of time so you have a way back if you eventually replace Windows.
That makes sense. I tend to overthink things and worry that one wrong click will destroy everything, so trying it on an older computer or live USB first would probably help me get comfortable.
