You miss the /mnt/d_sda2 so it is /mnt/d_sda2/boot/grub/grub.cfg to be editing the file that will be read on that partition when mounted as the new / with the sed command. You edit the running file with your sed command you use in the step 3 without editing the file on the mounted partition it will never find the new /. And the /@ in the EFI grub.cfg is not present in my file in your step 2.Thanks again for your responses. So far no luck. Many adventures in `grub >` and `(initramfs)`, but the changes I made in the 3 files failed to produce a bootable system.
I'll summarize what I've done. Maybe then my mistakes will be obvious.

2. Update `/boot/efi/EFI/debian/grub.cfg` from,toCode:
search.fs_uuid b7bdceb4-660a-4951-94cd-df9412b74f93 root hd0,gpt3 set prefix=($root)'/@/boot/grub'configfile $prefix/grub.cfgCode:
search.fs_uuid e042a944-8efa-4772-b46e-a24b878b4f7e root hd0,gpt2set prefix=($root)'/@/boot/grub'configfile $prefix/grub.cfg
3. update `/boot/grub/grub.cfg` using the sed replace command,Code:
sed -i "s/b7bdceb4-660a-4951-94cd-df9412b74f93/e042a944-8efa-4772-b46e-a24b878b4f7e/g" /boot/grub/grub.cfg
5. reboot... which lands me in the `grub>` prompt
No idea what I'm missing.
Thanks again,
