 |
| BIOS, the file controlling your computer's configuration, has to know about the new drive. Boot up and watch the screen. A message will tell you which key to press to enter BIOS' Setup program. |

 |
|

 |
| In Setup find the section in which your hardware is listed and, from the notes you took, fill in the information that will lead the BIOS to recognize the new drive. |

 |
| Allow the computer to boot up completely. If the second drive is not recognized by Windows, shut down and check your connections and your BIOS data. If the drive is OK, shut down and then replace the cover. |

| Partition and format the new drive. Reinstall your programs. Note: Some drives come with software that will prep the drive for you. |
