Windows 10 is one of the most popular operating systems in the world, and it’s widely used by individuals and organizations alike. However, with the increasing adoption of UEFI (Unified Extensible Firmware Interface) firmware, many users are wondering if it’s possible to install Windows 10 without UEFI. In this article, we’ll delve into the world of UEFI and BIOS, explore the differences between them, and provide a step-by-step guide on how to install Windows 10 without UEFI.
Understanding UEFI and BIOS
Before we dive into the installation process, it’s essential to understand the basics of UEFI and BIOS. Both UEFI and BIOS are firmware interfaces that connect the operating system to the hardware components of a computer. However, they differ significantly in terms of their architecture, functionality, and features.
What is BIOS?
BIOS (Basic Input/Output System) is a traditional firmware interface that has been used in computers for decades. It’s a 16-bit system that uses a Master Boot Record (MBR) to boot the operating system. BIOS is limited in its functionality and can only support a maximum of four primary partitions on a hard drive.
What is UEFI?
UEFI is a 32-bit or 64-bit firmware interface that’s designed to replace BIOS. It uses a GUID Partition Table (GPT) to boot the operating system and can support up to 128 primary partitions on a hard drive. UEFI also provides advanced features such as secure boot, fast boot, and network boot.
Can I Install Windows 10 Without UEFI?
The answer to this question is yes, you can install Windows 10 without UEFI. However, there are some limitations and requirements that you need to be aware of.
Requirements for Installing Windows 10 Without UEFI
To install Windows 10 without UEFI, you’ll need to meet the following requirements:
- Your computer must have a 64-bit processor.
- Your computer must have at least 2GB of RAM.
- Your computer must have a BIOS firmware interface.
- Your hard drive must be formatted using the MBR partition scheme.
Limitations of Installing Windows 10 Without UEFI
While it’s possible to install Windows 10 without UEFI, there are some limitations that you need to be aware of:
- You won’t be able to use the secure boot feature, which provides an additional layer of security for your computer.

Can I install Windows 10 on a non-UEFI system?
Yes, you can install Windows 10 on a non-UEFI system. Although UEFI (Unified Extensible Firmware Interface) is the recommended firmware type for Windows 10, it is still possible to install the operating system on a system with traditional BIOS (Basic Input/Output System) firmware. However, you may need to perform a clean install rather than an in-place upgrade, and you may not be able to use some of the advanced features that are available on UEFI systems.
It’s also worth noting that Microsoft recommends using UEFI firmware for Windows 10 installations, as it provides a more secure and reliable boot process. If your system has UEFI firmware, it’s recommended to use it instead of BIOS. However, if your system only has BIOS firmware, you can still install Windows 10, but you may need to perform a clean install and configure the BIOS settings manually.
What are the system requirements for installing Windows 10 without UEFI?
The system requirements for installing Windows 10 without UEFI are similar to those for installing Windows 10 on a UEFI system. Your system will need to meet the minimum hardware requirements, which include a 1 GHz or faster processor, 2 GB of RAM (32-bit) or 4 GB of RAM (64-bit), and 20 GB of free disk space (32-bit) or 32 GB of free disk space (64-bit). You will also need a valid product key and a compatible BIOS version.
In addition to the minimum hardware requirements, you will also need to ensure that your BIOS is configured correctly. This may involve setting the boot order to prioritize the installation media (such as a USB drive or CD/DVD), disabling any secure boot features, and ensuring that the SATA mode is set to AHCI (Advanced Host Controller Interface) or IDE (Integrated Drive Electronics). You may need to consult your system’s documentation or manufacturer’s website for specific instructions on configuring the BIOS settings.
How do I configure my BIOS settings for a non-UEFI Windows 10 installation?
To configure your BIOS settings for a non-UEFI Windows 10 installation, you will need to enter the BIOS setup utility. This is typically done by pressing a key (such as F2, F12, or Del) during the boot process. Once you are in the BIOS setup utility, you will need to navigate to the boot settings and set the boot order to prioritize the installation media. You may also need to disable any secure boot features and set the SATA mode to AHCI or IDE.
It’s also a good idea to save your changes and exit the BIOS setup utility. Your system will then reboot, and you can proceed with the Windows 10 installation. If you are unsure about how to configure your BIOS settings, you may want to consult your system’s documentation or manufacturer’s website for specific instructions. Additionally, you can try searching online for tutorials or guides specific to your system model.
Can I upgrade from Windows 7 or Windows 8 to Windows 10 without UEFI?
Yes, you can upgrade from Windows 7 or Windows 8 to Windows 10 without UEFI. However, you will need to perform a clean install rather than an in-place upgrade. This means that you will need to back up your files and settings, and then perform a fresh installation of Windows 10. You will also need to ensure that your system meets the minimum hardware requirements for Windows 10 and that your BIOS is configured correctly.
It’s also worth noting that upgrading from Windows 7 or Windows 8 to Windows 10 without UEFI may not be possible if your system has a 32-bit processor. Windows 10 is only available in 64-bit versions, so you will need to ensure that your system has a 64-bit processor before attempting the upgrade. Additionally, you may need to purchase a new product key, as the upgrade process may not be able to transfer your existing product key.
What are the limitations of installing Windows 10 without UEFI?
There are several limitations to installing Windows 10 without UEFI. One of the main limitations is that you will not be able to use some of the advanced features that are available on UEFI systems, such as secure boot and fast boot. You may also experience slower boot times and reduced system security. Additionally, you may not be able to use some of the newer hardware features, such as NVMe (Non-Volatile Memory Express) storage devices.
Another limitation is that you may not be able to install Windows 10 on a system with a 32-bit processor. Windows 10 is only available in 64-bit versions, so you will need to ensure that your system has a 64-bit processor before attempting the installation. Additionally, you may need to perform a clean install rather than an in-place upgrade, which can be more time-consuming and may require more technical expertise.
Can I convert my BIOS to UEFI after installing Windows 10?
Yes, it is possible to convert your BIOS to UEFI after installing Windows 10. However, this process can be complex and may require technical expertise. You will need to ensure that your system’s motherboard supports UEFI firmware and that you have a compatible UEFI firmware version. You will also need to back up your files and settings, as the conversion process may require a clean install of Windows 10.
It’s also worth noting that converting your BIOS to UEFI may not be possible on all systems. Some systems may not support UEFI firmware, or may require a hardware upgrade to support UEFI. Additionally, the conversion process may not be supported by all motherboard manufacturers, so you may need to check with your system’s manufacturer before attempting the conversion.
How do I troubleshoot issues with my non-UEFI Windows 10 installation?
If you experience issues with your non-UEFI Windows 10 installation, there are several troubleshooting steps you can take. First, ensure that your system meets the minimum hardware requirements for Windows 10 and that your BIOS is configured correctly. You can also try booting in safe mode or performing a system restore to a previous point when the system was working correctly.
If you are experiencing issues with the installation process, you can try checking the installation media for errors or trying a different installation method (such as using a USB drive instead of a CD/DVD). You can also try searching online for tutorials or guides specific to your system model or error message. Additionally, you can try contacting Microsoft support or your system’s manufacturer for further assistance.
