Lenovo Yoga 300 Boot Issues

[Alistair]

I have LL 3.0 x64 installed from a usb on two systems currently.  My HTPC installed without issue.  However, my Lenovo Yoga 300 is the problem.  I have it set to legacy in the BIOS and am able to boot from the live installation stick and install to the internal 32 GB MMC in the laptop. However, when I reboot after the installation, I am getting the message "No bootable device -- insert boot disk and press any key".  I have gone through the settings in the BIOS but cannot get it to work.  I had tried Peppermint OS 7.0 previously and this installed via UEFI without any problems.  However, I would prefer to run LL

Any help greatly appreciated, thanks
