Yes, recovering grub is a routine operation, but you have to
get all the details correct.

If you can easily access your backup of grub.cfg, try restoring
it to the problem drive and see if it works.
If that doesn't work, I suggest to post the grub.cfg that used to work here,
together with the output of 'lsblk -f' when all the drives that you need
to create a restoration setup are active.
That will help us guide you with much less guesswork.
