How do I remove the roles?

Hi all, reading in the moodle forums I was able to solve a problem with users unable to read the news forum posts on the home page by assigning their homepage role to student, but I misoverrided the roles to admin. Now admin has two roles-guest and student. How do I remove the two roles from admin? i.e. How do I restore the admin's original role (without any changes)?

Any ideas? Thank you in advance!
