Course Description
A fundamental skill of all Linux System Administrators is the ability to install the operating system and deal with any Boot issues. In this course you will learn about the boot process and how to install RHEL. This course will also cover some common boot and installation issues and how to deal with, or troubleshoot, those problems. This course is one of a series in the Skillsoft learning path that covers the objectives for the Red Hat Enterprise Linux 7 RHCSA exam (EX200).
