I've been interested in switching from Windows to Linux because I'd like to use an open-source operating system and try something different. Linux Mint seems beginner-friendly, but I'm not very tech-savvy and I'm worried about accidentally losing files or making my computer unbootable.
My computer only has one SSD, so buying another drive isn't ideal. Can I safely shrink the existing Windows partition and install Mint alongside it? I've heard that dual-booting can cause problems with GRUB, especially after Windows updates, and I'm nervous about corrupting data or not knowing how to recover the system.
Would it be better to try Mint from a bootable USB first, use an old computer if I can find one, or install it directly on the current drive? I'm willing to buy another storage device if that is genuinely the safest option, but I'd like to understand the free alternatives first.

If your backups are ready, you can also simply replace Windows with Mint instead of dual-booting. Mint is fairly approachable, and you can always reinstall Windows later using prepared installation media. Before taking that route, make sure you have copies of your personal files and confirm that the applications and games you need will work on Linux.
Regardless of the installation method, don’t rely on the single SSD as your only copy of important data. A second drive isn’t strictly required for dual-booting, but a separate backup is strongly recommended.
A spare computer is the least stressful way to learn. An old laptop or desktop that you don’t rely on can let you experiment with installation, settings, and troubleshooting without putting your main Windows system at risk. A spare internal or external drive is another good option, especially if you temporarily disconnect the Windows drive while installing Linux.
You don’t need to be an expert, but Linux does involve reading instructions and troubleshooting sometimes. Starting with a live USB or old computer is a good way to build confidence before committing your main machine.
Before installing anything, make two kinds of backup: a normal copy of your important files and, ideally, a complete image of the SSD. Tools such as Clonezilla or Rescuezilla can create an image you can restore if something goes badly. Keep the backup disconnected from the computer afterward so it cannot be affected by an accidental formatting choice.
You can also make a bootable Mint USB and test it without installing. The live session lets you check whether your Wi-Fi, graphics, sound, and other hardware work. It won’t change the SSD unless you launch the installer and confirm changes.
Dual-booting from one SSD is possible. The usual process is to back up your files, shrink the Windows partition to create unallocated space, boot the Mint installer from a USB drive, and choose the option to install alongside Windows. 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 by booting a Linux live USB and reinstalling GRUB. The important part is having a backup and a Windows recovery or installation USB ready before changing partitions. Also, don’t proceed until you understand exactly which partition the installer is modifying.
That makes sense. I think my biggest issue is that I tend to overthink things and worry that one wrong click will destroy everything. Having recovery media and a proper backup would probably make me feel much safer.
I may have an older laptop stored away, so I’ll check whether it still works. That could be a much better way to get comfortable before touching my main computer.
