What am I doing wrong in trying to boot via USB?
I have a Lenovo Yoga 3 ultrabook, it's just over a year old. I have made a bootable Windows 8.1 USB flash drive. My aim is to dual boot it with Windows 10. However, I'm not having any luck booting from it. I have read several websites regarding booting & setting a priority in BIOS for the USB device. I went into BIOS & in the 'Boot' section all the 4 items are 'Enabled', does this mean I don't have to move the USB to the top position. I had trouble initially upgrading to W.10, (a lot of default apps were missing.) I worked with 3 individuals at Microsoft & they did several tests remotely but all were unsuccessful, in the end the last person re-installed W.10 via a USB flash drive. But in the process they fouled up my option to revert back to W.8.1. That is why I made a bootable W8.1 USB flash drive. Thanks for any advice.
