Make a Lenovo Yoga 2 Pro boot to USB?
-
You need to enable Legacy mode in the BIOS, otherwise it's looking for a UEFI partition to boot from, and that rules out pretty much all USB devices.
-
My Acer is the same way - I haven't been able to boot from a Linux thumb drive (started a thread about it).
Similar to AJ - I changed to the UEFI setting to legacy - didn't help any. I have yet to manage to boot from USB ... and have set it aside for now.

Are you sure? I thought you could boot into UEFI from USB - if you can't how can you install Windows 8.1 or Windows 10 on a ultrabook in UEFI mode?

One thing for sure, you need to disable Secure Boot - which is probably somewhere else in the setup.

Here is a tutorial I've used in the past

This is the other part I forgot. This is critical.

If you're installing 8, 8.1 or 10, then yes, that's fine. However, if you're installing 7 or Linux, then you need to enable Legacy mode.

I found instructions for Ubuntu on UEFI as well.
-
That's the tool I use to format USB to boot UEFI
-
I recently tried to install Windows 8.1 on a Lenovo X1 - but it failed and failed..
I built my USB drive using the Windows 7 cd to USB tool - which has worked a ton in the past.
But now that i think about it probably failed because I didn't have a GPT partition on the USB. sigh.

You can and should install newer versions of windows in UEFI mode (or Linux) , if you don't you'll mess up the install when you switch back.

Yep. That's what locks out other devices booting.

But this can be solved if the OS you want to install has a cert for UEFI - and Ubuntu does.. so you can install that into the UEFI.
