While NO PCBIOS and EFI only for ISO 9660 image, burn the image to SandDisk USB stick, plug it into laptop, then boot laptop and enter UEFI mode, there are two boot options in UEFI system. Here is the steps: $ echo 'MACHINE = "genericx86-64"' >> conf/local.conf $ echo 'MACHINE_FEATURES:remove = "pcbios"' >> conf/local.conf $ echo 'IMAGE_FSTYPES:pn-core-image-minimal = " live"' >> conf/local.conf $ bitbake core-image-minimal $ sudo dd if=tmp/deploy/images/genericx86-64/core-image-minimal-genericx86-64.rootfs.iso of=/dev/sda Boot laptop and entery UEFI mode ... Boot mode is set to: UEFI UEFI BOOT: UEFI: SanDisk UEFI: SanDisk 2 ... In this case, PCBIOS is not used, calling isohybrid for ISO 9660 image is not necessary, and do not call isohybrid for ISO 9660 image could remove duplicated boot option in UEFI mode. Add var-ENABLE_ISOHYBRID to disable or enable isohybrid, but still enable isohybrid by default as usual. User could set ENABLE_ISOHYBRID = "0" in local.conf to disable it Signed-off-by: Hongxu Jia <hongxu.jia@windriver.com> --- meta/classes-recipe/image-live.bbclass | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-)
