I'm planning to stop dual-booting and install Linux as my main operating system on the 500GB M.2 drive that currently contains Windows 11. I also have two additional 2TB M.2 SSDs that I'd like to use for personal files and possibly applications. How difficult is it to keep my data, Flatpak apps, and other programs on separate drives while keeping the Linux system files on the main drive? I may also need to reinstall Windows 11 at some point. Is that as simple as creating a bootable USB installer, and what should I prepare beforehand to avoid activation or driver problems?

When setting up the extra SSDs, make sure they are mounted automatically at boot using stable filesystem identifiers rather than device names. Also check which drive the bootloader is being installed to, especially if multiple drives are connected, so a future reinstall does not unexpectedly affect the Linux boot setup.
For Windows, download the official Windows 11 ISO or use Microsoft’s boot-media tool to create a bootable USB drive. Boot from it, choose the correct edition, and install it to the intended drive. Back up anything important first, since selecting the wrong disk can erase data. If Windows was preinstalled, the license may be stored in the motherboard firmware; otherwise, linking the activation to your Microsoft account provides another way to reactivate the same edition later.
Separate storage for documents, media, and other personal data is easy. Applications are less consistent because traditional packages may install files in several locations under /usr, /opt, or your home directory. It is usually simpler to leave system packages on the Linux drive and use the extra SSDs for data, games, virtual machines, and application-specific libraries.
Keeping personal files on another SSD is straightforward. You can format it and configure it to mount automatically, either somewhere such as /data or as your /home partition. Putting /home on a separate drive keeps your personal files separate from the operating system and makes future Linux reinstalls easier. Flatpak applications can also be configured to use storage on another drive, although the exact setup depends on your distribution and Flatpak configuration.
So Flatpaks can be installed there too, but regular applications may be spread across several system directories?
Before reinstalling Windows, save your important files and have network, chipset, storage, and graphics drivers available if possible. The installer often gets most drivers automatically, but having them ready helps if networking does not work immediately. You can also run Windows in a virtual machine instead if you only need it occasionally, though demanding games and hardware-dependent software may perform better with a native installation.
My Windows 11 Pro activation is already linked to my Microsoft account. I’ll make sure I reinstall the Pro edition and back up anything needed before starting.
