Reboot the System: Restart your Oracle Linux 8 server.
Interrupt GRUB Menu: When the GRUB boot loader menu appears, press the e key to edit the selected kernel entry
Edit the Kernel Line:• Use the arrow keys to find the line starting with linux or linux$appropriate_version.

Accessing the Root File System (if using rd.break)
When using rd.break, the system drops you into an emergency prompt before mounting the real root file system read-write. To perform maintenance or reset a password:
- Remount the root file system as read-write:bash
mount -o remount,rw /sysroot
Change root into the sysroot environment:bash
chroot /sysroot
Perform your administrative task (e.g., reset the root password):bash
passwd root
Exit and reboot:bash
