70 / 100

Changing or upgrading a motherboard can be quite a nightmare if you haven’t done it before. It is almost like building your computer from scratch. Like every other part, you are going to connect the hard disc back to the motherboard. And you might ask, Do I need to reformat when upgrading motherboard

Well, the right answer is you don’t always have to but it is always good to do it. See, the hard disc with a pre-installed OS is going to have some issues with the new motherboard. And if the motherboard is completely different from the previous one, the issues will be severe. 

On the other hand, you may install a motherboard that is almost similar to the previous one. And the chances are you will have no issues. But in all cases, a fresh install is always better. Let us explain everything precisely.

Do I really need to reformat when upgrading the motherboard? – Detail Discussion

Changing or upgrading the motherboard of your computer can be of different types. You might just install the same motherboard because the previous one was damaged somehow. You might install a quite similar motherboard. And the third way is to install a completely different motherboard.

And the answer to your question will depend on the way you are upgrading your motherboard. Let’s say you are installing the exact same motherboard or a somewhat similar one with the same chipset and CPU. Then, you can skip the reformatting part and you should be okay in most of the cases.

When a similar motherboard is installed the OS on the hard drive has almost no problem with it. It finds similar drivers installed in the new motherboard and works just fine. It will ask you after booting up the computer if you have changed the hardware. You agree and face no issues.

But if you are going to install a completely different motherboard then the scenario is different. With the preinstalled OS on your hard drive, it is going to have issues with the new motherboard. It will search for the old drivers and won’t be able to find them. And this can cause big problems in your system.

So, in this case, you should move your data to another hard disc and format the one you will install. Then connect the formatted hard disc to the new motherboard. And then install a fresh OS, whatever version you prefer. It will be compatible with the motherboard from the beginning and will have no issues.

The next thing is to re-install your OS to the empty hard drive and with the new motherboard. You can find all the necessary drivers and install them. And then restore all your saved data from the backup hard drive. Everything is new and nothing is lost.
