How to keep the executable files added to Windows 8 USB bootable image?

By nugulus ·
Firmware update file by Dell is in Windows format. I created a bootable usb using Windows ISO image, added the firmware file to the image. The added file is seen if I map the usb drive. When I boot up the usb to the Windows 8 Repair command prompt, I don't see the firmware file, why? If I use FreeDOS instead of Windows 8, the firmware file is seen at any time, but the file won't run in dos environment.

How to keep the executable files added to Windows 8 USB bootable image?

Following are the steps that you need to follow in order to edit a bootable ISO to add files in Windows.

Step 1: If you haven’t installed a file archiving program, please visit this page to download 7-Zip (free) and install the same. If you’re using any other file compression tool such as WinRAR or WinZip, you don’t need to install 7-Zip.

Step 2: Navigate to the location where your bootable ISO file is located, right-click on it, click 7-Zip, click Extract files and then select a new folder in your preferred location to save contents of the ISO file. If you’re using WinRAR or WinZip, simply right-click on the ISO file to see Extract option.

Step 3: Once the contents of the ISO have been extracted, simply copy the file(s) that you would like to include in the ISO file.

Step 4: Now, we need to create a bootable ISO file out of those extracted files. In order to do so, we need to download and install another free program called ImgBurn.

Step 5: Launch ImgBurn, click Create image file from files/folders option.

Step 6: Switch to the Advanced tab. Click on the Bootable Disc tab that appears when you click on the Advanced tab.

Step 7: Next, click on the small browse icon that appears next to the Source box and browse to the new folder containing the contents of your extracted ISO file plus the newly added files.

Once done, select a location to save the bootable ISO file that you’re going to build in a couple of minutes. To do so, simply click the browse icon next to the Destination box and then browse to the location where you want to save the ISO and then enter a name for the new ISO file.

Step 8: Under Bootable Disc tab, select the option labelled Make Image Bootable, select Emulation type as None (Custom), and then type 8 in the box next to Sectors To Load. If in case, you’re working on Vista ISO, please enter 4.

Step 9: Finally, click the small browse icon that appears next to Boot Image box and browse to the Boot folder located in the newly created folder where you have saved extracted ISO file contents. Select the file labelled etfsboot.com file and then click Open button.

Step 10: Click Build button to start the process of building your bootable ISO image file. Click Yes or OK when you see the following three dialog boxes to continue building the ISO file.
