Thanks Darren! Below is the grub.cfg: # Automatically created by OE serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1 default=boot timeout=10
menuentry 'boot'{ linux /vmlinuz root=/dev/sda2 ro rootwait quiet console=ttyS0,115200 console=tty0 } I use this command to create the USB disk: scripts/contrib/mkefidisk.sh -v /dev/sdc os.hddimg /dev/sda By the way, I found the ISO image is okay(dd the ISO to usb disk), in the ISO, there is initrd in the grub.cfg file, so I think the root cause is the grub cannot boot without initrd. Did you test the hddimg + mkefidisk.sh ? 2015-04-01 0:18 GMT+08:00 Darren Hart <dvh...@linux.intel.com>: > You'll need to provide more detail for us to help. Exactly how is it > failing.
