Can I replicate my working Linux setup on another PC?

You can clone the entire Linux drive to the other computer, but it isn’t always the cleanest approach. Linux generally handles different hardware well, though you may need to reinstall or adjust the NVIDIA driver and regenerate the bootloader configuration. Make sure the partition UUIDs and UEFI boot entry are correct, and keep a full backup before cloning. Installing Mint fresh and transferring your personal data is usually safer.

If you want an exact duplicate for testing, a disk image or clone can work, and the old installation could even be run in a virtual machine. For a daily driver, though, I’d use the existing PC as a reference: write down installed applications, copy your data and selected dotfiles, then configure the new hardware independently. That avoids carrying over unnecessary driver and bootloader baggage.

A fresh installation followed by copying your home directory is probably the best balance. Your documents and many application preferences live under /home/your-user, especially hidden folders such as .config and .local. Copy only the settings you actually need rather than blindly replacing every system file, since hardware-specific or old configuration can cause confusing problems.

You can also save a list of installed packages and recreate the software environment on the new machine. For example, export the packages with the package manager, install Mint on the target PC, then install the packages from that list. Back up any deliberate changes in /etc separately, particularly display, printer, networking, or boot settings, and reapply them one at a time.
