Hi Community, Dell Imaging Technology Support team brought your discussion to Dell's technical support department. Below are a couple notes to keep in mind regarding Dell's operating system download availability ( the process known as Dell Hosted Image ). -Eligibility for Dell Hosted Image varies by service tag -Dell Hosted Image hosts images available from Windows 7 SP1 and up -There are 2 methods of download which are explained below -If your service tag does not have an image available through the below 2 methods of download you can contact Dell technical support and mention article ID SLN308469. Dell technical support can use this ID in order to check on eligibility and/or to resolve image availability for specific service tags -For eligible service tags image availability between the 2 download methods will vary. For example: An image may be available through browser download only and not available in the Dell USB Recovery tool -If an image download is available through the below explained browser download option then Dell later makes the same tag's image available through the USB Recovery tool, the browser option will then no longer be available. The goal is to move away from the browser option and move all eligible downloads to the USB Recovery Tool. Method 1. Download through Browser: 1. Go to support.dell.com 2. Enter your service tag then click 'submit' 3. Click on the 'Drivers & Downloads' tab 4. Pull the 'Catagory:' drop down and click on 'operating System' 5. Click the blue download button next to the listed image option 6. Enter your service tag again and proceed to download Method 2. Download Through the Dell USB Recovery Tool: 1. Visit [URL] 2. Follow the instructions listed on the page    
NOTE Prerequisite:  A valid service tag with entitlement to the preferred Windows OS.  .e.g If looking for Windows 10, then the service tag must show sold with Windows 10.  After you download the Windows recovery image file, follow the instructions below to create a bootable USB drive or DVD.
