Apple Event: May 7th at 7 am PT
I'm trying to erase my hard drive and after restarting, hitting cmd + R etc, I've found that the erase button is always greyed out. Anyone know what I can do to in this situation.

Hello Deimne,
Thanks for using Apple Support Communities.
If the erase tab is grayed out when trying to do an erase and install of OS X, then please ensure you're following the proper procedure as outlined below.
Use these steps if you need to erase a disk before installing OS X:
- Before you begin, you need to be connected to the Internet.
- Choose Apple menu > Restart, and then hold down the Command (⌘) and R keys while the computer restarts.
- Select “Disk Utility,” and then click Continue.
- Select your startup disk from the list on the left, and then click the Erase tab.
- From the Format pop-up menu, select Mac OS Extended (Journaled), type a name for your disk, and then click Erase.
- After the disk has been erased, choose Disk Utility > Quit Disk Utility.
- If you’re not connected to the Internet, choose a network from the Wi-Fi menu in the right corner of the menu bar (in the top-right corner of the screen).
- Select Reinstall Mac OS X, click Continue, and then follow the instructions.
