How should I partition a 240GB SSD for a Windows/Linux dual boot?
Asked by

I'm planning to use Linux Mint as my daily driver alongside Windows on a 240GB SSD. The other drives are reserved for family members, so I'll be setting up the dual boot on this drive. I'd like to create a shared partition that both operating systems can access occasionally. What partition layout and sizes would you recommend? Also, is it safe to mount the Windows partition in Linux, and are partitions mounted automatically during installation or only when I choose to mount them? I'm new to disk management, so I'd appreciate practical advice and warnings about common mistakes.

There isn’t one perfect layout, since it depends on how much space Windows, Linux, applications, and personal files need. A 240GB drive is workable, but it can become cramped if you install large games or programs. Let the Linux installer use sensible defaults, then adjust the Windows and Linux sizes based on your actual usage. A shared NTFS data partition is a reasonable choice for files that both systems need to access.

Back up anything important before changing partitions. Ideally, make a full disk image as well as copying your personal files somewhere else, and make sure you know how to restore it. Partitioning is usually safe when done carefully, but a mistake or interruption can still make the system unbootable.

Linux doesn’t normally mount every Windows partition permanently unless you configure it to do so. You can mount a partition manually through the file manager when needed, or set up automatic mounting later. Accessing a Windows partition occasionally is generally fine in a dual-boot setup, but don’t use it as the location for Linux programs or a Linux home directory. If this isn’t your own computer, get permission before modifying the disk.

QuietOrbit51: Avoid putting Linux system files, your Linux home directory, or Linux applications on NTFS. It’s mainly useful as a shared data area. Also, fully shut Windows down rather than using hibernation or Fast Startup before accessing its partitions from Linux.
