Guide to Replace a Motherboard without Reinstalling Windows

Guide to Replace a Motherboard without Reinstalling Windows

Replacing the motherboard is one of PC manufacturers’ most difficult tasks. Electronics have a limited life span. Given the advent of technological advances, motherboard upgrades might be a pivotal requirement to keep your PC up-to-date. Upgrades help improve the PC’s speed, performance, and durability in today’s world. In contrast, replacing the motherboard risks damaging the significant components of a device. Therefore, they must be chosen carefully. Thankfully, there are several ways to replace it. If you have a backup, then the linked data is automatically saved. And you will most likely lose your data if you do not own appropriate backups. 

One of the few tried and tested ways to replace the motherboard is completely reinstalling Windows. You can replace Windows with version 10, 8, or 7. However, reinstalling Windows tends to absolve the data stored in its component. Therefore, it is recommended that you backup all the important data before reinstalling Windows or upgrading your motherboard. This option might not be appropriate if you do not have the necessary peripherals to back up your data. The risk factor is quite great, as the system may fail to reboot, or there may not be a driver to boot the Windows. This occurs after changing the latest components and upgrading the motherboard. 

Therefore, it helps to use this method when the appropriate guidance, precautions, and software are provided before reinstallation.

We have provided the key points for you to go through before dealing with such issues.

When Windows 10 still has not booted?

If Windows 10 is still not booted, choosing the wrong boot mode while booting will be a problem. For example, the upgraded motherboard has UEFI boot mode, and the previous motherboard attached had MOBO work with a legacy BIOS. We have provided the steps that will help to resolve those issues below.

  • Restart PC and direct it to BIOS
  • Select Boot and go to Legacy boot priority and change the boot as per your system requirement and support.

Windows License Key Activation

Windows license key has three different types that are listed below:

OEM: OEM expanded stands for Original Equipment Manufacturer. These have integrated licenses in your hardware, and direct links to the motherboard are bought.

Retail: Retail refers to those who purchase licenses that are to be referred to various PCs.

Volume: Volume licenses are possessed by organizations that buy products in bulk. Organizations like schools, colleges, etc., choose this as it helps them install it on various PCs and requires only a single key for authentication. If the system’s license is connected to the internet, all the Windows with the same key gets activated simultaneously, making it convenient. 

How to check your license key?

The license key is pre-integrated with the device. To check if your license key is available, go to Windows My Computer, select Properties from the menu above, or right-click on This PC and check its properties. After navigating to Properties, scroll down and find the product ID. If not located, search the OEM for the license key in it. There is no available OEM, volume, or retail in some cases. 

If you received a license key from Microsoft,  it is referred to as a retail key. OEMs typically have Windows 10 | 8 | 7 pre-installed or integrated. At the same time, large organizations buy license keys. 

Another way to find Windows 10 License Key Type –

Go to the start menu, locate the search bar, and type Command Prompt. Click on the first option and provide input as slmgr-dli in the command prompt. This will make the Windows Script Host screen appear. The description contains the type of License key used in your system.

Activation of Windows 8.1 or Windows 7 product key –

With new versions of Windows being announced, the older version of Windows, 7 or 8.1, gets free upgrades. However, some of the users do not get these updates, and for those, the license key provided in the older system is changed to a digital license key for the new setup.

To upgrade to Windows 10, you can use the steps provided below. It helps to get your work done with ease by providing a digital license key for the older version of Windows 7|8|8.1:

  • Press the Windows key, + I
  • Go to update and security
  • Open activation panel
  • Click on the Change product key located on the right side under the category of the Update Product key
  • Type the License Key for Windows 7|8|8.1
  • Select Next
  • Now, Windows 10 will be activated.

Is Windows still having issues?

If Windows still does not reboot, the issue might be in the driver conflict which can be overcome by replacing the product and getting a new one. These problems are mostly encountered with Windows 8 and 7, though cases can be found with the Windows 10 version as well. You can boot the recovery drive troubleshooting and diagnostic tools for additional help in all these cases.


The motherboard is an important component of a PC that requires special attention. Reinstalling Windows will always result in data loss unless you back up your data in any viable format. Most often, these issues occur when you update your PC. If you reinstall Windows on your PC,  you will not be able to retrieve the data. 

Suppose, for some reason, the booting fails and still does not solve the issues described. In that case, it is a component failure, and you can claim a warranty if available or replace the product within the specified period. 

Detailed instructions on how to replace the motherboard without reinstalling Windows have been provided. We have considered various methods to be employed depending on the situation, so please read in advance. 

An effective way to change MOBO without reinstalling Windows has been explained in detail. This will help you reactivate the new Windows on your PC.

Frequently Asked Questions

Is it possible to move the license of Windows 10 to another computer?

The answer is yes. For this, you need to remove the license from the previous PC, and then you can transfer it to another PC. If you are looking for free up-gradation of Windows, it might not be a good idea as it will be deactivated beforehand, which results in no Windows upgrade. 

Can I change the CPU, like the motherboard, without reinstalling Windows?

Yes, it can be done by the same processor. It allows the replacement of hardware such as CPU or motherboard, but we suggest you check it beforehand. Failing to boot the PC means that the system won’t be working. So, please check that all the components are compatible, and go for the motherboard up-gradation and CPU, as mentioned earlier in this article.

Does the changing of the motherboard result in computer data loss?

No, replacing any hardware will not change data loss unless it is the hard disk. All the data is saved on the hard disk, and upon its corruption, data loss must be processed. Reinstalling Windows will result in data loss as all the data in the hard disk is being formatted in that process, and the new data is loaded as per the user requirements. 

Is reinstalling Windows without replacing a new MOBO and CPU possible?

There are many reasons for reinstalling Windows, such as limiting new hardware components. One of the reasons is that your previous system might not be responding to your PC, and hence you need to upgrade it to the newer version of Windows.

Is changing the motherboard without reinstalling Windows 10 possible?

Yes, you can. However, the method is complicated for the new users but is reliable and has a 100% accuracy. We have discussed the three ways to do so in the article. You can select any of the methods mentioned per the situation as each method is suited to a particular situation or purpose. But to be on the safer side, please create a backup so that the data stays safe with you.
