UEFI install on clean SSD

I've been having some trouble with my existing Windows 10 installation, and I'm planing to resinstall the OS from scratch on a brand new SSD that's fresh out of the box.

I want to install it with UEFI and Secure Boot from a USB, as I'm currently using Bios.

I've installed OSs before so I know the basics about partitions and so on, what I'm not certain about is how I can be certain that I'm installing Windows 10 as UEFI, and not as legacy bios.

Is there a tickbox or an option that you need to select during the installation process, or is this something that you need to select from your MB.

I plan to install from a USB stick. I've already downloaded the ISO and made the stick as I previously upgraded from Window 7.

Set the UEFI firmware to boot UEFI only and enable secure boot. That's what it will do. After install look at your SSD partitions and you will see a FAT32 EFI System partition that the computer boots from.

The following article might be helpful. As NavyLCDR says it is all down to how you set the BIOS. Make sure you select the UEFI USB drive if you end up with a choice.

Boot to UEFI mode or Legacy BIOS mode.

1. Boot the PC. As the firmware starts to run, press the key that opens the boot device menu. For example, press the Esc, F2, F9, F12, or other key to enter the firmware or boot menus.

2. On the boot device menu, select the command that identifies both the firmware mode and the device.

Note

You might see separate commands for the same device. For example, you might see UEFI USB Drive and BIOS USB Drive. Each command uses the same device and media, but boots the PC in a different firmware mode.

When you boot from the Windows installation media in Legacy BIOS mode, then Windows setup creates a MBR partitioned disk.

When you boot from the Windows installation media in UEFI mode, then Windows setup creates a GPT partitioned disk.
