Resetting the Root Password: A Step-by-Step Approach

We'll use emergency mode to reset the password. The methods differ slightly depending on your Fedora version.

Method 1: Fedora 39 and 38

This method is verified for Fedora 39 and 38.

Step 1: Accessing the GRUB Menu

Power on your system and repeatedly press ESC to access the GRUB boot menu. Select your Fedora kernel and press 'e' to edit boot parameters.

Example GRUB menu (Fedora 38):

Step 2: Entering Emergency Mode

Locate the line starting with "linux ($root)/vmlinuz...", navigate to the end (END or CTRL e), and append:

<code>rw init=/bin/bash</code>

Press CTRL x or F10 to boot into emergency mode.

Step 3: Resetting the Password

Your root filesystem should be mounted read-write. If not, use: mount -o remount,rw /. Reset the password using:

<code>passwd</code>

or

<code>passwd root</code>

Enter and confirm your new password.

Step 4: SELinux Relabeling

To ensure correct security contexts (if SELinux is enabled):

<code>touch /.autorelabel</code>

Step 5: Rebooting

Exit single-user mode and initiate the boot process:

<code>exec /sbin/init</code>

Allow SELinux relabeling to complete (may take several minutes). Press ESC if only the Plymouth screen appears to monitor progress.

Step 6: Logging In

Log in with your new root password.

Method 2: Fedora 37 and Older Versions

This method is tested on Fedora 37, 36, and 35, and should work on older versions.

Step 1: Accessing the GRUB Menu (Same as Method 1)

Step 2: Identifying the ro Parameter

Locate the ro parameter in the boot parameters.

Step 3: Modifying the ro Parameter

Replace ro with rw init=/sysroot/bin/sh. Ensure a space between rw and init=/sysroot/....

Press Ctrl x to enter emergency mode.

Step 4: Mounting the Root Filesystem

In emergency mode:

<code>chroot /sysroot/</code>

Step 5: Resetting the Password (Same as Method 1)

Step 6: SELinux Relabeling (Same as Method 1)

Step 7: Rebooting

Exit single-user mode and reboot:

<code>exit</code>

<code>reboot</code>

Monitor SELinux relabeling progress.

Step 8: Logging In (Same as Method 1)

Conclusion

Resetting your Fedora root password is achievable through these steps. Remember to always use a strong password and exercise caution when performing these administrative tasks. The images are retained in their original format.
