This tutorial suggests a method to “remotely (re)install” RedHat based Linux distros (Fedora, RHEL, CentOS, etc). Proceed with utmost caution, you will lose all current data on your hard drive!
We make use of the ‘vnc’ application that is available on most Linux OS/bootloaders. However, my instructions below are for GRUB. I use TightVNC viewer to connect to the VNC server, you might want to download and install this on your PC now.
To reinstall, you must be able to access your server through SSH and be able to edit files as the root user. If you are unable to do this, you must be able to escalate privileges in your shell by using su OR have sufficient permission on the server to edit the boot loader’s files (/etc/grub.conf)
