To resolve the issue for missing or expired certificates on Boot Media, a new certificate needs to be created:
1. Recreate the Boot Media by going in the Configuration Manager Admin Console to Site Database --> Computer Management --> Operating System Deployment.
2. Right clicking on Task Sequences and choosing Create Task Sequence Media.
3. Step through the Task Sequence Media Wizard to create the appropriate media.
4. In the Security screen, locate the Create self-signed media certificate option.
5. Make sure that the Set start date is set to either today or some date in the past.
6. Make sure that the Set expiration date is set to some date in the future.
7. Finish stepping through the Task Sequence Media Wizard to finish creating the ISO or USB Flash Drive.
8. Go to Site Database --> Site Management --> <Site_Code> --> Site Settings --> Certificates --> Boot Media and verify that there is now a valid non-expired non-blocked Certificate.
9. If using CDs/DVDs, once the ISO is created, create a CD/DVD from the ISO and dispose any previous OSD CDs or DVDs.
10. If using a USB Flash Drive, make sure to recreate all USB Flash Drives be redoing steps 1-8 above.

There is no supported way to update the certificate on existing media. You must create new media (for which Abhishek kindly copied and pasted the procedures from the official documentation for you).
