If you are lucky your computer manufacturer bundled one with your box.I chose to make one on my Ubuntu machine, using a copy of Windows 7 running in Virtual Box, adapting the instructions for making a rescue disk from this web site.
Checking dates on unofficial Dell support web sites suggests that this may also apply to other Dell models since 2010 or even earlier.
The first step is to get information about your current system.
In Ubuntu you can check the BIOS version with the following two commands: You need information about your computer's hardware when querying the manufacturer's website.
Just as this cannot be run under Ubuntu (or any other Linux), .
This is in spite of anything it may say on the download page about being compatible with earlier versions of Windows; using any legacy DOS-type environment the runs, but exits without doing anything except printing out an annoying message. And how do we do that on a single-boot Ubuntu machine (or even a computer running legacy Windows, like XP)?
The key ingredient at this point is a Windows 7 Repair Disk.There are several ways to obtain one, including buying one from sources on the internet, or making friends with someone who has a Windows 7 computer.For Dell this is often printed somewhere on the underside in the form of a Service Tag and an Express Service Code.If this is not easy to read, the information can be obtained in the following way: 1) Install libsmbios: with the key information in the BIOS version, the System ID, the Service Tag, and the Express Service Code.Armed with the above information, go to the Dell web site and download the appropriate driver(s) for your particular computer.So far so good, but you will notice that the download is a Windows executable.
