+### Objective
+
+Resetting the root password in RHEL7/CentOS7/Scientific Linux 7
+
+### Requirements
+
+RHEL7 / CentOS7 / Scientific Linux 7
+
+### Difficulty
+
+MODERATE
+
+### Instructions
+
+Things have changed in the RHEL7 world and so has the preferred way of resetting the root password. Although the old way of interrupting the boot process (init=/bin/bash) still works, it is no longer bulletproof and recommended. 'Systemd' uses 'rd.break' to interrupt the boot. Let's have a quick walk through the whole procedure. 
+
+### Boot into the minimal mode
+
+Reboot the system and press `e` while being on the kernel list page, before the autoboot starts the system automatically. You get into the edit mode.
+
+### Interrupt the boot process
+
+In the kernel string - at the end of the line starting `linux 16 /vmlinuz- ect` type `rd.break`. Then Ctrl+X to reboot. The system boots into the initial ram drive and it's mounted on /sysroot In this mode you are not required to type the password.
+
+### Remount the system so that it can read and write
+
+```
+ switch_root:/# mount -o remount,rw /sysroot/
+```
+
+### Make /sysroot your root
+
+```
+ switch_root:/# chroot /sysroot 
+```
+The command line will change slightly.
+
+### Change the root password
+
+```
+sh-4.2# passwd 
+```
+
+### Load SELinux policy
+
+```
+sh-4.2# load_policy -i 
+```
+
+### Set context type on /etc/shadow file
+
+```
+sh-4.2# chcon -t shadow_t /etc/shadow 
+```
+Note: You could bypass the last 2 steps by creating an autorelabel file instead, but autorelabeling might take a long time.
+```
+sh-4.2# touch /.autorelabel 
+```
+For that reason, and despite it is easier, it should be regarded as the 'lazy option', and is not recommended.
+
+### Exit & reboot
+
+Exit & reboot and log in with your new root password.
