Installing Linux on a physical machine
To install CentOS Linux from full DVD, we need to download an ISO image from the CentOS website. Browsing to CentOS Linux download page at https://www.centos.org/download/. This DVD ISO image can be burned to an optical disk, or we can create a USB thumb drive from it.

To make a bootable CentOS seven USB thumb drive using Windows, we can use Win32 Disk Imager. Browse to SourceForge.net/projects/win32diskimager. and download. There are other tools on Windows that can burn an ISO image to a thumb drive, but Win32 Disk Imager works reliably, so I recommend it.
