So i was using an image which is CentOS-8-x86_64-1905-boot.iso
, there is an installation source which you need to select, so I went to this site to find out the address of the mirror. I found the one nearest to me by using the kickstart one. See below for what i mean.
As usual… Centos expects you to know what you are doing and there will be no guided installation… so good luck.
