UEFI boot disabled, doesn't boot windows

Like what @Nayr438 said, I think your USB is only geared up for legacy boot.

So I have created a live USB with Ubuntu 19.10, it runs fine and no problem. To get it to boot on my laptop I need to disable UEFI Boot, when I do and select my USB to boot, it boots into ubuntu. But when I select the drive with windows(10) installed on it, it doesn't find the bootable windows. And I instead get this screen. (with the Ubuntu USB removed or else it boots straight into Ubuntu) 

 

If I re enable UEFI Boot in the bios then it boots into windows fine but can't find the USB as a bootable option. 

 

I can switch between the two but it is a pain, if there is a way I can have both or anyone has advice it'd be greatly appreciated.

You need UEFI boot enabled to boot into Windows. You can switch it back to legacy but I do not recommend that. Also, Ubuntu will work on UEFI...

Make sure your Install Media was written in DD Mode. Use Etcher if unsure.

Leave UEFI Boot on, you should only disable Secure Boot as it can be finicky.

Cheers guys (@NZgamer), going through the install process again I noticed I hadn't partitioned a space for EFI
