    SteveSi received kudos from Aryeh Goretsky in Sysrescue Boot to USB Problem   
    Did your Yoga come with Windows 10 32-bit or Windows 10 64-bit?
    To UEFI-boot, the USB drive needs to have a FAT32 partition with a \EFI\BOOT folder on it containing one or more .EFI boot files.
    For systems with a UEFI 64-bit BIOS - you need \EFI\BOOT\BOOTX64.efi
    For systems with a 32-bit UEFI BIOS - you need \EFI\BOOT\BOOTIA32.EFI
    If your system came with 64-bit Windows installed then it needs to boot from the BOOTX64.EFI file.
    If your system came with 32-bit Windows, it probably has a 32-bit UEFI BIOS and so needs to boot from BOOTIA32.EFI.
    Many ISOs are 64-bit UEFI only...
