Do you need to enable UEFI to run Windows 10? The short answer is no. You don't need to enable UEFI to run Windows 10. It is entirely compatible with both BIOS and UEFI However, it's the storage device that might require UEFI.
Do I need to enable UEFI to run Windows 10
Windows 10 and BIOS doesn't support more than 2 TB of storage space. On the other hand Windows with UEFI can boot from hard disk which is greater than 2 TB. Its the reason why most of the computers and laptops are coming with UEFI instead of legacy BIOS
Let's get a little deeper, so you understand why UEFI is essential, and if you have UEFI, you should enable it. UEFI stands for Unified Extensible Firmware Interface. It is the logical successor to the EFI and not BIOS. While most of the consumers were happy with less than 2 TB hard disk or SSD, this is a limitation for Servers - thats why Intel started developing UEFI. UEFI uses GPT (GUID Partition Table) like BIOS uses MBR (Master Boot Record).
If you are planning to have storage more than 2TB, and your computer has UEFI option, make sure to enable UEFI.
Another advantage of using UEFI is Secure Boot. It made sure that only files which are responsible for booting the computer boots up the system.
If you are planning to install Windows 10 via a bootable USB drive, there is one thing you should know about UEFI. Many manufacturers only include the driver for FAT32 which causes NTFS not to work. It results in an issue when you install Windows 10 with NTFS formatted bootable drive. Make sure to format the USB drive as FAT32.
Are you using a storage device more than 2TB? Do you have a system with UEFI? Let us know in the comments.
Frank says below in the comments:
We now need to have NTFS in order to be able to create a Windows 10 installation media on a USB flash drive. Depending on the system used, you may end up with one of two different configurations:
- Two partitions in which the first is a smaller FAT32 partition that contains the bootloader and additional files needed to load the NTFS partition. And then a second, larger NTFS partition where the installation media is stored.
- A single NTFS partition which contains both the bootloader and the installation files.
The first configuration works best for older systems where the BIOS is unable to boot from partitions that aren't FAT formatted. The second configuration works on most modern computers since they're able to boot directly from an NTFS formatted partition.
