[yocto] Yocto procedure to write generated image to hdd

[Iván Castell]

After writting the .hddimg file to a USB-pendrive I have mounted the
pendrive to analyze contents in my laptop. It contains the following files:

    ./EFI/BOOT/grub.cfg
    ./EFI/BOOT/bootx64.efi
    ./initrd
    ./ldlinux.sys
    ./libcom32.c32
    ./libutil.c32
    ./rootfs.img
    ./startup.nsh
    ./syslinux.cfg
    ./vesamenu.c32
    ./vmlinuz
    ./ldlinux.c32

This is the content of /EFI/BOOT/grub.cfg file:

    $ cat EFI/BOOT/grub.cfg
    # Automatically created by OE
    serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1
    default=install
    timeout=3

    menuentry 'install'{
    linux /vmlinuz LABEL=install-efi root=/dev/ram0
rootwait console=ttyS0,115200 console=tty0
    initrd /initrd
    }

    menuentry 'boot'{
    linux /vmlinuz LABEL=boot root=/dev/ram0  rootwait console=ttyS0,115200
console=tty0
    initrd /initrd
    }

I found this link with useful information:

    https://www.yoctoproject.org/downloads/bsps/danny13/atom-pc

According to it, "it is likely the BIOS cannot understand the physical
layout of the disk".

This sounds strange to me, because USB-pendrive boots fine when the .wic
image is burned into the USB-pendrive. But anyway, I have checked BIOS
USB-related settings and this is my current setup:

Main information:

    BIOS Vendor: American Megratrends
    Core Version 5.009
    Compilancy: UEFI 2.3; PI 1.2
    BIOS ID: N29NL009 x64

USB-related information:

    USB Module version: 8.11.02
    Legacy USB Support [Enabled]
    USB 2.0 Controller Mode [HiSpeed]
    XHCI Hand-off [Enabled]
    EHCI Hand-off [Disabled]
    USB Mass Storage Driver Support is [Enabled]

    General UDisk 5.00 [Auto]

I don't know what can I do to manage this issue. I'm really blocked on
this, any help to would be very helpful. Thanks in advance!!
