How to disable uefi bootable usb

[Mkazem]

I want to disable uefi boot on bootable usb and boot normally.

Because i want to install win 10 on mbr partition. I dont want to format hard disk.

There is no option to disable secure boot.

Laptop model is Asus X550L

How did you get the windows install on the flash drive??

And whats the hdd formatted in now if windows is on it?

There should be 2 options when booting from the use, a uefi and non-uefi options.
Failing that, if you have the ISO, use Rufus to create a bootable usb and select the mbr option.

Yes, that's what I actually did, I even used rufus to create bootable usb. but I only did it for uefi systems which worked for me. I wanted to install windows for my friend and I realized her laptop did not support UEFI. so made bootable usb for mbr.
