Q: How do I delete everything off of my hard drive?
I have an old iMac computer(from 2008), and I would like to delete the contents on my hard drive. Is there a way of doing this, and can It be done without deleting the operating system?
iMac, OS X Yosemite (10.10)

It can't be done easily without deleting the OS, but...
Boot holding CMC-r & use Disk utility there, CMD+r should have an option to reinstall the OS after erasing the boot drive.
Or...
Open System Preferences>Accounts, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.
In the same pref pane highlight your old account, click the little minus icon, then use Disk Utility to Secure Erase Free Space.
