A live DVD or memory stick version of any recent Linux distro will allow you to boot. You can then mount the original disk as, say, /mnt. Go to /mnt/etc and edit the root password to be null or cut-and-paste a known password in. Reboot and set it.

I lost my CentOS 7 root password, so I tried booting the OS in single
user mode
but it prompts me for the root password when the system boots,
Any ideas?
