What do you mean by "Created a kick-start image of Cent-OS 7.6 1810"? Do you mean you created your own iso image containing a kickstart file? If so then I suspect you put the wrong volume label on it.

Yes created my own iso image CentOS 7.6 and some perl/python packages. And created an ami out of it to launch on aws. This process was working fine for CentOS 6.10. But not for CentOS7.6. Fails to boot with with the following "Warning: /dev/disk/by-label/x2f does not exist".

Following is my grub.cfg

I'd suggest labelling it something that doesn't contain a special character like /.
