To be honest, I don't really know, but looking it up I found a few related articles, like for checking initrd... amongst others.

One hack is to rename the file so it's not found and is re-generated based on the latest successful boot process (live).
The boot process will just take a little bit longer, the virtual machine ram disks were meant to speed up the boot process before todays speed of devices.

The / files maybe links to /boot/ files... be warned!

Burying into the kernel is no longer on my wish list, but you may research some of it here... Duck Duck Go search...

gnu/linux create vmlinuz initrd update-initramfs

in particular...

https://dev.to/er_dward/understanding-the-initrd-and-vmlinuz-in-linux-boot-process-534f
https://www.kernel.org/doc/html/latest/admin-guide/initrd.html
https://www.baeldung.com/linux/initrd-vs-initramfs

The only process I have used lately is to rebuild initramfs to include bluetooth device(s) (bt headphones, etcetera) for more complete functions during the boot process, although my system does not rely on bt to boot to a working system.

Deleting the old vmlinuz, initrd.img may be risky... have a good search yourself, and backup by renaming instead of deleting files so you can back-track if you need to. It's outside my scope of knowledge now, although I have dabbled in kernel config modifications and making/installing in the long past.

I hope this gives you something to work with.

thanks for reply.
#GRUB_DEVICE_UUID="bab95b18-9201-499e-b96b-6ab89bfd41e0"
its line i did when try to get it work

hmm i do not know how but its working now. grub now use correct uuid.
may be this cmd help?
tune2fs -U bab95b18-9201-499e-b96b-6ab89bfd41e0 /dev/sdb1

maybe the boot system is picking up the old UUID from a vmlinuz file from the old system (hdd)

maybe, how check it, or update vmlinuz?

Just one glaring observation...

Your grub uuid for / is commented.

/etc/default/grub

#GRUB_DEVICE_UUID="bab95b18-9201-499e-b96b-6ab89bfd41e0"

Un-comment (#) that line and run update-grub again.
reboot to check...

1. copy hdd ext4 partiotion to ssd ext4
2. install grub to ssd partition
3. update ssd fstab with new UUID
4. update-gub

try to boot in grub boot menu ssd entry still use old uuid from hdd partition
