Yes, I see the latest screenshot now. Must have missed that one.

Harry, that error almost always indicates you do not have the drivers
for PIIX compiled into the kernel. I assume you are not using an
initramfs so that driver must be compiled in, not a module.

In make menuconfig, it's found at Device Drivers -> Serial ATA and
Parallel ATA drivers

Similar for the file system driver (presumably ext2|3|4) for the
partition hosting /boot, that too must be compiled in (not a module)
