How to Install CentOS 6 Minimum Without Internet

When I first installed CentOS 6 minimum, I couldn’t figure out how to install the OS without internet connection, but eventually, I figured it out.

The OS that I’m using is CentOS 6.7 minimum, and normally, you’d need Internet connection while installing the OS because you would select URL for the installation method.

To create the bootable USB flash drive, I’ve created a blog post for the instructions. Insert a bootable USB flash drive into the machine and boot into CentOS 6.7.
