No, that's not how it works.  What happens is that before doing anything
 with Linux, grub reads the kernel image and the initrd image both into
RAM at different start addresses.  If there is a problem doing that,
then grub will error out before the kernel boot begins.

Once it has them loaded, grub is completely done... it jumps into the
Linux kernel image.  Once the kernel decompresses and finishes getting
started, it mounts the initrd copy in memory and starts running the
"init" script it finds in there.  That script loads some critical
modules (to access the HDD controllers for example) from the initrd
filesystem and then tries to mount the real root filesystem from the
HDD.  It is at that point Karl was dropping dead.

Well, yes Karl apparently made the problem go away somehow leaving
nobody the wiser.
