I've had a 2021 ROG Zephyrus G14 running Windows 10 Home for several years, and it contains many photos, videos, programs, and other important files. I'm planning to build my first desktop gaming PC from scratch and would like to reuse the laptop's existing SSD in it. Is that practical, and can I keep the current Windows installation, or should I use the SSD only for storage and install Windows separately? I'd also appreciate advice on backing up my files and preparing the drive safely before moving it.

Before wiping anything, make a backup and verify that the backup actually contains the files you need. You could install a new SSD for Windows and games, then use the laptop’s SSD as a secondary drive, but the old Windows folders and programs won’t function like a normal portable application library. Personal files can be copied over, while most programs and games should be reinstalled on the new system. Keeping the old drive untouched as a backup until everything is transferred is the least risky option.
You can reuse the SSD, but the safest approach is a clean Windows installation after moving it to the desktop. A laptop installation contains drivers and manufacturer software intended for the G14, so Windows may have compatibility problems when booted with completely different hardware. First copy your photos, videos, documents, and any other important files to an external drive or cloud backup. Then create a Windows installation USB, install the SSD in the new PC, boot from the USB, delete the old Windows partitions during setup, and install Windows onto the unallocated space. Restore your personal files afterward rather than copying the entire old installation back.
Check what kind of SSD is inside the laptop before buying parts. The G14 generally uses an M.2 NVMe drive, so the new motherboard needs an M.2 NVMe slot that supports the drive’s size. Physically moving it is usually fine, but don’t assume the existing Windows installation will transfer cleanly. Also, a Windows license that came with a laptop is normally an OEM license tied to that original machine, so it may not activate on the new desktop. You can install Windows without entering a key and deal with activation afterward, or purchase a separate license.

So the general process is to back up my important files first, wipe the SSD during the Windows installation, and then copy only my personal files back once the new system is working?
