You might need to reinstall and/or reconfigure the boot loader for the following reasons:

but from previous helpers i am do not hear even suggest for REINSTALLING grub, they all speak only about update grub

You need to run grub-install after grub version updates which occur during normal system package updates. Had you been re-running grub-install and update-grub after grub version updates on the original drive? It won't cause a problem unless you need to run update-grub. Other OS's sometimes automate this, or change Grub versions infrequently. This is true for UEFI systems, historically BIOS boot was rarely affected. If you hadn't run update-grub for a while in your original OS copy, or had run grub-install from an iso that had a different grub version, you could have got a mismatch quite easily. Also besides that there's a huge amount of code and auto detection run by little commands like mkinitcpio, update-grub and grub-install, if you copy a drive like you did, which is a non-standard thing compared to following the well documented and tested base install procedure on the wiki, you shouldn't be surprised to have to re-run them as the installation progresses. First you copy the files, then make it bootable which can involve some fun with Grub and UEFI BIOS setttings, then see if it boots and how far it gets. Often it won't go to the desktop as you found, then you debug and re-run stuff from the tty as I suggested - I didn't mention grub-install before as it seemed you had got a bootable system and it could also have stopped things from booting completely if you had got it wrong or run into UEFI BIOS issues - the idea is that running these things from the running OS will pick up the correct data and use the installed versions. Because there are so many possibilities you need to be prepared to fix them as they arise and make it up as you go along, but it's usually not that difficult. In 6 months time, packages will have updated and you might face different problems copying in the same way.
