Nothing in dracut cares about what partition it is on, and grub is not
finding the initramfs.  Grub is failing to find the boot.cfg files and
vmlinuz and inittramfs.  So either you have the wrong grub being
started or the right grub but it cannot find its config files.

Are you trying to move /root or /boot or is your /boot on /root
without a separate /boot?

When it was working, / , the root of the tree was on sda5.
That partition included everything except /var and /home ,
which had their own separate partions.

Did you set /dev/sda3 as bootable in whatever program you used to
partition? (if not efi).

No.
Neither sda5 nor sda3 has ever been set as bootable.
I was under the impression that the grubs did not care.
I've never changed a bootable flag.
sda1 , a Windows 7 partition is the only partition marked bootable.

My general plan would be to set the new partition bootable with the
partitioning program (fdisk there are options to find the option to
set bootable) (this all assumes you aren't using EFI).

liveboot it.

That means boot a live disk, correct?

mount the new installs root (/)  under /mnt

aka sd3 aka local3slash

mount the new install boot device under /mnt/boot

I do not have a separate boot partition,
so no need for this?

mount -o bind /dev/ /mnt/dev
mount -o bind /dev/pts /mnt/dev/pts
mount -o bind /proc /mnt/proc
mount -o bind /sys /mnt/sys
this allows the chroot system to access devices and other critical
resources to be able to run.

Now what?
Run dracut?

Try using man dracut.  Man is your friend; trust man.
