move operating system to new hard driveBuying a new desktop or laptop computer is always good geeky fun. Although computers have generally accelerated beyond the level needed for mere “adequate” use, the performance wars haven’t calmed down in the slightest. New PCs also often have cool features like touchscreens.

The only problem with buying a new PC – one that has existed for years and that hardware technology can’t solve – is when you want to move the operating system to your new hard drive. Simply copying your operating system from one hard drive to another doesn’t work, and trying to install your old hard disk into your new PC may result in issues as well. There is a solution to this issue, however.

Making Your Clone

Operating systems are finicky beasts. They don’t like to be copied directly over to a new hard drive, and the operating system on your new PC will most certainly won’t let you copy over it (at least as long as it’s running). There’s good reason for this, in terms of curtailing security threats and preventing accidental operating system damage, but it certainly makes moving a full operating system more difficult.

Since copying operating system files the old-fashioned way doesn’t result in a bootable operating system being transferred over, you’ll need to rely on a process called cloning. Cloning a hard drive replicates all or some of the files on it and also replicates the file structure of the hard drive. This creates a perfect bootable copy.

Cloning Problems

Unfortunately, while cloning does create a perfect copy of your hard drive and the operating system on it, it isn’t always the best solution. The process of cloning is itself a bit complex, and it will presumably require that you at some point have an extra hard drive, since directly cloning your existing drive to the drive on your new PC would wipe out the new PC’s drive entirely.

The other issue with cloning is that creating a perfect copy does not guarantee that your old operating system will work with your new PC. When an operating system installs itself on a PC, it also installs a plethora of drivers relating to your PC’s hardware. If you transfer your existing OS to a new PC, much of that hardware is going to be different – and that can be a shock to your OS. It will have drivers for certain hardware, but that hardware is gone. It will try to compensate by installing new drivers automatically, but if it can’t find the right drivers it will likely crash.

You may be able to repair the operating system if you still have the install disc around, or can load the installer onto another bootable device, but this can be a frustrating process.

Transferring Files

If cloning sounds like too much work, or you’ve tried it and found that it failed, you can forgo trying to transfer the entire operating system and instead transfer only your files and system settings.

Windows has a utility for this called Windows Easy Transfer. As the name implies, the goal of the software is to transfer everything from your old PC to your new PC that could easily be lost. It doesn’t transfer software, but it does transfer documents, photos, music, program settings, etc. Once the process is complete, your new PC should behave much as the old one did, and should have all of your personal files as well.

The Windows Easy Transfer software is free, but a direct USB connection between computers requires that you buy a Windows Easy Transfer Cable. You can skip this, however, by connecting two computers via a network and transferring files that way.

Linux users can accomplish this same task by using a utility called Rsync Grsync - A Simple GUI to Help You Use 'rsync' Easily [Linux] Grsync - A Simple GUI to Help You Use 'rsync' Easily [Linux] Read More . Apple users aren’t left out in the cold, either – OS X comes with a utility called Migration Assistant that will help you transfer files to your new Mac from an old one.


Personally, I don’t recommend that most users go with cloning, although it is the only option that results in a true full operating system transfer. Utilities that transfer all critical system information and your personal files usually give you a better result – they transfer important data, but don’t leave room for driver compatibility issues that could cause crashes.
