The following tutorial walks you through backing up your computer to an external hard drive connected to your computer through a USB port using the most commonly selected options. You can back up using other target devices and use other options; please see the Image for DOS manual for complete details.

To select menu items in Image for DOS, use the arrow keys to select the desired option and then press Enter to display the next screen. You can press the Esc key to undo menu selections and move back to the previous menu. Even if you press the Esc key, Image for DOS remembers the selections you have already made throughout the Image for DOS session.

  1.  Attach the external hard drive you intend to use to store your backup to a USB port on your computer.

  2.  Insert your Image for DOS boot disk into the appropriate drive and boot your computer. If your computer contains more than one CD/DVD drive, please make sure that you insert your Image for DOS bootable disc in one drive and no other CD/DVD drive contains a bootable disc.

    To boot your computer using this boot disk, you might need to edit your computer’s BIOS settings to reorder your drives and permit your CD/DVD drive to boot your computer before your C: drive boots your computer. As your computer begins to boot, you should see a message—before you ever get to Windows or your operating system—that tells you what key to press to enter Setup—typically the Delete key, F2, or F12. Once in the BIOS, follow the instructions provided in your BIOS to reorder the boot sequence and permit your CD/DVD drive to be examined for boot information before your hard drive. If your system starts by offering you the option to select a boot menu, you can use the boot menu to identify the drive you want to use to boot.

    Note: If your computer tries to boot from the external hard drive, remove the drive, reboot your computer.

  3. On the Image for DOS Main Menu/Select Operation screen shown below, Select Backup and press Enter.

    Note: If your external hard drive isn’t attached, attach it, wait about 10 seconds, and then select Backup and press Enter.

  4.  On the Backup/Select screen shown below, select Full Backup and press Enter.

  5.  On the Backup From/Select Drive Interface screen shown below, select BIOS (Direct) and press Enter.

    Note: Selecting BIOS (Direct) is faster in most cases, but, if you encounter problems using this choice, try selecting BIOS instead.

  6.  On the Backup From/Select Source Drive screen shown below, Image for DOS displays all available hard drives. Select the drive or the drive containing the partition you want to back up and press Enter.

  7.  On the Backup From/Select Item to Backup from HDn screen shown below, select the drive that you wish to backup by highlighting the drive and pressing Spacebar.

  8.  Use the Backup/Select screen shown below to select Single File Set and press Enter.

  9.  On the Backup To/Select File Access Method screen shown below select File (Direct) and press Enter.

  10.  On the Backup To/Select Drive Interface screen shown below, choose USB and press Enter.

  11.  Image for DOS displays the screen shown below while searching for your external USB drive; if Image for DOS can’t find your external USB drive, see the following Knowledge Base article for suggestions:

  12.  Press Enter when Image for DOS finds your external USB drive and displays the screen shown below.

  13.  On the Backup To/Select File Location on HDn screen shown below, select the drive on which you want to store the backup and press
     Enter; if the drive contains partitions, select a partition instead of the drive and press Enter.

  14.  On the Backup To screen shown below, accept the suggested file name or type a name for your backup and press Enter. You do not need to type the .tbi file extension—just the path and file name itself; Image for DOS will automatically add the extension.

    Tip: The suggested file name includes identifying information about the backup. In the figure below, "d" identifies the Image program and option used to create the backup (Image for DOS - BIOS Direct). The "0" identifies the number of the drive you selected to back up, and the subsequent characters append the date and time you created the backup to the file name. If you are backing up a partition instead of a complete drive, the partition ID number would appear after the drive number.

  15. On the Backup Options screen that appears, select the options you want to use and press Enter. Most people select Validate Byte-for-Byte along with the options pre-selected by Image for DOS. Selecting this additional option makes your backup take longer but ensures the integrity of the backup by catching any unknown system related problems; by selecting this option, you’ll know you have a valid backup in case you need to restore it.. For details on using the rest of the options shown on this screen, see the Image for DOS manual.

    To select these options, use the arrow keys to highlight the option and press Space Bar.

  16. Select Next to display the Summary screen, which summarizes the parameters of your backup.

    When you select Start, the imaging process begins, and a progress bar appears on-screen. You can interrupt the backup and validation operations at any time by pressing the F12 key. Image for DOS will ask you to confirm that you want to cancel before it interrupts the current operation. When Image for DOS finishes, this message appears.

  17.  When the backup finishes, press Enter to redisplay the main menu for Image for DOS shown below.

  18.  Select Exit and, when prompted, remove the Image for DOS boot disk and press Enter to reboot your computer.
