Q: No disk appears when reinstalling OS X

Followed the following steps and now trying to reinstall OS X but no disk appears.

 

You can use these steps to erase the files on your startup disk and install a new copy of OS X:

  1. Before you begin, make sure your Mac is connected to the Internet.
  2. Restart your Mac. Immediately hold down the Command (⌘) and R keys after you hear the startup sound to start up in OS X Recovery.
  3. When the Recovery window appears, select Disk Utility then click Continue.
  4. Select the indented volume name of your startup disk from the left side of the Disk Utility window, then click the Erase tab.
  5. If you want to securely erase the drive, click Security Options. Select an erase method, then click OK.
  6. From the Format pop-up menu, select Mac OS Extended (Journaled). Type a name for your disk, then click Erase.
  7. After the drive is erased, close the Disk Utility window.
  8. If you’re not connected to the Internet, choose a network from the Wi-Fi menu.
  9. Select the option to Reinstall OS X.
  10. Click Continue and follow the onscreen instructions to reinstall OS X.

    Did you reformat the disk and was there a pre-existing problem with the disk and is that why you are trying erase and install?

    well the trackpad was jumpy. I thought it might have a virus. I only followed those steps. later I went to terminal typed in the code: diskutil cs delete "Macintosh HD"

    after that I tried to reinstall osx and the disk was there.

    Now I have it installed but the trackpas is still jumpy.
