You need to have a console access for running this operation.

1. Inside java or HTML5 console, please reboot your server and wait for the GRUB menu

2. Inside the GRUB menu select your first entry and press “E” key to edit.

3. Find a line with ro and change it to rw

4. After rw add init=/sysroot/bin/sh

5. Press CTRL+X to boot your server in rescue mode

6. Inside shell, type chroot /sysroot and press enter
