How to Download and Use the Dell Operating System Recovery Image in Microsoft Windows

The Advanced Mode in Dell OS Recovery Tool allows you to create a USB recovery media using an operating system image file (ISO file format). This is useful if you downloaded the operating system recovery image using a Linux, Mac, or Android device. You can create a USB recovery media on a Windows-based computer using the Dell OS Recovery Tool.

How to create a USB recovery media using an ISO image

1. Download and install the Dell OS Recovery Tool on a Windows computer.
2. Click Start, then open the Dell OS Recovery Tool application.
   NOTE: Click Yes in the User Account Control prompt. The Windows user account must have administrator privileges to install the Dell OS Recovery Tool application.
3. Click Search (magnifying glass icon).
4. In the open window, browse to the folder location where you have saved the operating system ISO image file.
5. Select the .iso file and click Open.
6. Click Next.

8. Under USB drive, select the USB flash drive that you would like to use to create the USB recovery media and check the button "I understand that the selected drive will be reformatted and existing data will be deleted."
   WARNING: Dell recommends that you back up any important data from the USB flash drive. The Dell OS Recovery Tool formats the USB flash drive and all the data on the USB flash drive will be erased permanently.

If you download a large file through a Dell online application (such as the Dell OS Recovery Tool), you may receive a "Not enough space on drive" error. This is due to a space limitation on the hard drive where the files are being saved to. Some operating system recovery images can be up to 16 GB in file size.

To correct this error, free up additional disk space on the hard drive. For information about freeing up disk space in Microsoft Windows, see the Dell knowledge base article How to Free up Disk Space in Microsoft Windows.

If you have an external hard drive or secondary hard drive with more disk space, select that drive to save the files.

You can try to resolve this issue by using a different brand of USB drive. Certain brands of USB drives may cause this issue.
