How to Create Bootable BIOS ISO Image File

Using Nero Burning ROM Version 5.5

Most Dell Forum users recommend to use ONLY the Floppy disk method of updating the BIOS. But you don't have a floppy disk. What do you do? This is becoming a bigger problem since Dell does not include the floppy disk standard on the newer notebook models and people are trying to save money by not ordering the optional USB floppy disk.

If you have access to another computer that has a floppy disk, you can create a bootable CD with the BIOS update on it and use it to flash the BIOS. Below is step by step instructions on how to create the bootable CD using Ahead's Nero Burning ROM.

NOTE: The following instructions refer to Version 5.5 of Nero Burning ROM. If you have version 6.0, visit here for instructions.


Step 1: Download the Floppy disk version BIOS update for your notebook and save it to a temporary folder. Then run (double-click) it to unzip the set of files. Follow the instructions to create a set of floppy diskettes. Click Here to see an example of what version to download. It is very important that you download the correct file.

The "Format Description" should read:
This file contains a compressed (or zipped) set of files. Download the file to a folder on your hard drive, and then run (double-click) it to unzip the set of files. Follow the instructions to create a set of floppy diskettes, and then use the diskettes to complete the installation.

Step 2: With the floppy BIOS disk that you just created in the floppy drive, start the Nero Burning ROM program.


Step 3

If the Wizard appears when you start the program, click on the "Cancel" button and click on File on the menu and select New. You can also use the key combination of CRTL + n.

Step 4

You should now see this window. Scroll down the left pane until you see CD-ROM (Boot). Double click on it.

Step 5

The Boot tab will now appear. Under "Source of boot image data", make sure that you select the A:\ Drive

Under the "Expert Settings" section, make sure everything is identical to this example. This is critical to creating a working bootable CD. The "Floppy Emulation" will make your notebook think that your CDROM is your A:\ drive.

Step 6

Click on the "Label" tab and enter your volume label. You should also make sure that the drop down list shows ISO9660. If it doesn't, click on the drop down arrow and select ISO9660.

Then click on the "New" button.

Step 7

If the computer that you are using has a CD burner in it, you can burn the image directly to the CDR or CDRW. I am going to assume that this computer does not have a CD burner and will create the ISO image file.

On the menu, click on "Recorder" and then "Choose Recorder". You could also use the key combination of CTRL + r. Choose "Image Recorder - Virtual Device" and then click on the "OK" button.

Then open the Write CD Dialog by clicking on the button that the arrow is pointing at.

Step 8

Click on the "Write" button.

Step 9

If you are burning the image directly to a CD, you will not see this dialog.

The Save Image File Dialog will appear. Select the folder that you want to save this image file to and name it. Select "Save as type" to be ISO Image Files (*.iso). This file type can be used by most CD burning programs.

Once you have done this, click on the "Save" button.

Step 10

The Write CD Dialog will appear and will show you the progress of the image creation.

Step 11

Once the image is created, you will have the option to Save, Print or Discard the messages. Normally, I just Discard them.

Step 12

You now have an ISO image file of the bootable CD BIOS update files that you can burn to a CD with your favorite burning software package.


Step 13: Now that you have created the Image File and burned it to a CD, you can update your BIOS safely. To update the BIOS, have the CD that you just created in the CDROM and reboot your notebook. When you see the Dell BIOS Splash Screen, hit F2 and set the boot order so that the CDROM is first in line. Save the change to the BIOS and exit the BIOS Setup. I would not suggest using F12 unless you are sure how your BIOS update takes place. Some of the updates automatically reboots the computer to finish the BIOS update. Now reset your BIOS Boot Order to however you want it.
