Laptop wont boot from usb flash drive

[HPlaptop51]

My HP 15-af131dx wont let me boot from a flash drive. I was able to boot from the flash drive on my hp mini 110, and in the past I have ran Ubuntu on a flash drive on the 15-af131dx and it has worked fine. How can I boot from the flash drive?

HP mini 110 boot manager. As you can see, the laptop sees the flash drive and alows me to boot from it.

 HP 15-af131dx boot manager. As you can see, it doesnt show the option to boot from the flash drive.

Hi:

A couple of suggestions you can try...If they don't work, unfortunately, I don't have any other suggestions.

1.  Go into the BIOS and enable legacy mode, which should disable secure boot.

2. Boot from one of the notebook's USB 2 ports.  It will not boot from a USB3 port.

When I tried to enable legacy mode I got this warning:

Should I try something else?

There is nothing else to try that I know of.

I don't know what the consequences would be if you change the setting.

Maybe you can change it back after you boot from the USB drive.

If you are wanting to install W7 you will have to change the setting because W7 will not work with secure boot enabled.

I changed the setting and windows 10 still boots up fine. I was able to boot from the flash drive.

That is great news.

Glad to have been of assistance.
