You do not press command with either of those.
Only press the 'c' key to boot to the DVD drive
press only the 'option' key to bring up a list of bootable devices.
Don't know if holding command affects anything since I haven't tried it - like preventing it from booting or if the boot process would merely ignore that key press.
'command R' is correct for booting to the recovery partition where you can then go to Disk Utility and partition/erase/format the drive
I cannot be held responsible for the things that come out of my mouth.
In the Windows world, most everything folks don't understand is called a virus.
