The above is the Standard Guide. At the end of the Standard Guide are a series of workarounds which allow one to use the Dell Skylake .iso for other All Editions of Windows 7 OEM covering Dell and non-Dell systems as well as workarounds to use the Dell Skylake .iso for Retail Licenses.

Introduction

Windows 7 Reached End of Mainstream Support in January 2015 and Windows 7 Pro Reached End of OEM Sales in October 31st 2016 while other Editions of Windows 7 Reached End of OEM Sales in October 2014. Due to Microsoft’s policies Dell are no longer allowed to ship physical installation media.

Although we requested this way back in 2009 when Windows 7 was first released and preinstalled on Dell Systems, Microsoft have finally conceded and allowed Dell to provide a proper digital distribution in the form of the Dell OS Recovery Tool but only for Windows 7 Pro OEM which is still the most popular OS for use in a Business environment. Home customers are expected to use Windows 10 which I recommend in most cases.

Dell released an up to date Windows 7 Pro .iso – the “Dell Windows 7 Pro Skylake Reinstallation .iso” which is updated to include USB 3.1 and Storage Controller support necessary for installation of Windows 7 Pro on up to 6th Generation Intel Skylake systems. This installation media also includes Internet Explorer 11. It will automatically activate on eligible Dell systems using Dell OEM System Locked Preinstallation.

The Dell Windows 7 Pro Skylake Reinstallation .iso created in March 2016 (including Updates until January 2016) is far superior to Microsoft’s own offering which is outdated to 2010. Only the Pro Edition is updated.

The Dell Windows 7 Pro Skylake Reinstallation .iso is also multi-lingual:

The Dell Windows 7 Skylake Reinstallation .isos in this guide will apply Dell OEM System Locked Preinstallation. For Windows 7 Pro the install will be keyless.

Eligible systems have a Windows Pro sticker:

win10Pro Win8Pro

Or alternatively a Windows 7 Pro COA (key not required, often found under the battery compartment):

Laptop COA

How to Tell What Generation of Intel System I Have?

I will reinforce the point that there is Windows 7 driver support on hardware up and including 6th Generation Intel Skylake systems. As a rule of thumb this is hardware purchased before Mid 2016. Newer systems do not have driver support and the installation of Windows 7 will fail, moreover Microsoft have deliberately rigged Windows 7 Updates to never install updates on newer hardware (in the slim event you manage to succeed to get Windows 7 installed).

Intel processors have the labelling system ibgxxx

  • where b is the brand modifier of the processor; 3 is entry, 5 is mid-entry and 7 is high-end.
  • g is the generation and g≤6 for Windows 7 driver support.
  • xxx is the Stock Keeping Unit

For more details see Intel Processor Numbers.

You will be unable to install Windows 7 Pro OEM natively on 7th Generation Intel Hardware due to the lack of driver support. However system’s with 7th generation processors are immensely more powerful than the hardware Windows 7 was designed for approximately a decade ago. Thus they can easily handle Windows 7 in a virtual environment.

Unofficial: The Windows 7 Pro System Licensed Internal Code (SLIC) 2.1 can be ported to a VM using VMware player so you can activate using Dell OEM System Locked Preinstallation. For more details see Porting SLIC 2.1 from your Host PC to the VM to allow Downgrade Rights from Windows 10 Pro to Windows 7 Pro.

Dell OS Recovery Tool

Download the Dell OS Recovery Tool:

http://www.dell.com/support/home/uk/en/ukdhs1/drivers/osiso/recoverytoolhttps://www.dell.com/support/home/us/en/19/Drivers/OSISO

Install the tool following the on screen instructions. Launch the tool:

If the Tool is ran on a Dell system to the left you’ll be able to select “This Device” and it will automatically lookup your Service Tag. Otherwise to the right you can manually input a Dell Service Tag.

The Windows 7 Download will display, 7.06 GB for Windows 7 Pro 64 Bit or 5.45 GB for Windows 7 Pro 32 Bit.

If your Service Tag is rejected try 5KR9DC2 for Windows 7 Pro 64 Bit 7GXLCS1 for Windows 7 Pro 32 Bit. N.B. Only Service Tags of UEFI BIOS Systems which shipped with Windows 7 Pro seem to be eligible. If your system shipped with Windows 7 Home Premium or Windows 7 Ultimate use Windows 10 Installation Media or see Convoluted Workaround at the End of this Guide.

Select Download.

It should say Download Completed! You may now close the program.

The Dell OS Recovery Tool should in theory allow one to make a Bootable USB Flash Drive however in my testing the following occurred. Therefore I recommend using Rufus to check the .iso checksums and make the Bootable USB:

Installation .iso Checksums

Open your Downloads folder. You will see a subfolder called Dell. The installation .iso you have downloaded will be present there. The installation .isos will have the following names with a suffix including the time you downloaded the .iso e.g. _20171207_0202

Windows 7 Profession 64 Bit Multi-Language:

  • G13K9_PW4KGA00_W7SP1PRO64_ROW(DL).iso

Windows 7 Professional 32 Bit Multi-Language:

  • MT5KY_N6N9GA00_W7SP1PRO32_ROW(DL).iso

Ensure that the .iso checksums match before using the .iso as there are often issues with incomplete downloads.

.iso checksums can be checked with Rufus (which we will also use to make the Bootable USB):

https://rufus.akeo.ie/

Rufus doesn’t need to be installed. Launch Rufus:

Select yes at the user account control prompt.

Select the load .iso icon:

Select your .iso and select open:

Select #:

This will give you the .iso checksums:

This will give you the .iso checksum which should match below.

Checking if your System has an UEFI Boot

Power down your Dell and then power up and Press [F12]. This will take you to your systems Boot Menu.

If it mentions at the top “Boot Mode” then you have a UEFI BIOS.

For Windows 7 64 Bit Installation:

  • The Boot Mode should be set to UEFI.
  • Secure Boot should be Off.
  • Legacy ROMs settings (not shown on the Boot Manager Screen) should be Enabled.
  • Note that early UEFI systems may not have Secure Boot and hence no need for Legacy ROM Settings.

For Windows 7 32 Bit Installation:

  • The Boot Mode should be set to Legacy.
  • Secure Boot should be Off.
  • Legacy ROMs settings (not shown on the Boot Manager Screen) should be Enabled.
  • Note that early UEFI systems may not have Secure Boot and hence no need for Legacy ROM Settings.

For details in Enabling these settings see Unified Extensive Firmware Interface (UEFI).

If it doesn’t mention at the top “Boot Mode” then you have an older system with a Legacy BIOS.

Creating a Bootable USB Flash Drive

Insert a 16 GB USB Flash Drive and launch Rufus:

Select yes at the user account control prompt.

Select the load .iso icon:

Select your .iso and select open:

For a UEFI system with 64 Bit Windows 7 ensure the partition scheme is GPT for UEFI is selected and the file system is NTFS.

For a Legacy system with 32 Bit Windows 7 or 64 Bit Windows 7 ensure the partition scheme is MBR for Legacy BIOS and the file system is NTFS.

Select Start:

You will get a warning informing you that data on your USB will be wiped. Select OK:

Wait for Rufus to make your Bootable USB you will see the green progress bar:

When its finished it will say Ready.

Windows Update

With the Updated Image of the Dell Windows 7 Professional .wim 192 Updates are preinstalled taking this Windows Installation Media up to date until January 2016:

Installation Instructions

To install Windows 7 see Windows 7 Installation in a UEFI BIOS or Legacy BIOS.


Notes for Other Editions

It is recommended to use Windows 10 if you have a non-Pro Edition of Windows 7 for the latest build of Windows 10 see here.

There is a Convoluted Workaround (for Advanced Users only) to install a non-Pro Edition of Windows 7. You need to use a Service Tag from a system which shipped with Windows 7 Pro (see the Dell OS Recovery Tool). Next you’ll need to delete the EI.cfg file from the Bootable USB to allow all Editions of Windows 7 to be installed. Next because the Windows Installation Media is out of date it is advisory and in some case mandatory to slipstream all the required drivers and Windows Updates to the other Editions in the boot.wim and install.wim in order to allow for Windows 7 to recognise your hardware. Finally you will need to manually apply Dell OEM SLP as these Editions won’t auto-activate. These steps will be discussed in detail:

Modifying the Bootable USB to Install other Editions of Windows 7

If the EI.cfg file is deleted from the sources folder of your Bootable USB you will be presented with the option to install all the Editions of Windows 7 present on the .iso during installation. This will allow you to Install Windows 7 Home Basic, Windows 7 Home Premium of Windows 7 Ultimate corresponding to your systems OEM License:

Open up the USB in Windows Explorer go to the sources folder and look for ei.cfg and delete it.

Common Issues using the 2010 Installation Media Windows 7 Installation Media on 2011-2016 Hardware

If one tries to use outdated installation media on a modern system the mouse and keyboard may not be responsive on the first screen because no USB 3.0 drivers are present:

no-usb-3-0

One can manage to get by this screen by use of a USB 2.0 port (or use of the USB Debug which makes the USB 3.0 port function as a USB 2.0 Port) or via use of the Laptop Touchpad/Keyboard.

If it is not possible to get around this, you must Slipstream the Drivers and Updates to your Installation Media (see below).

The next hurdle is the following error message due to the lack of SATA preinstallation drivers meaning the Windows setup cannot access the Storage Controller for the HDD/SSD during installation:

no-usb-3-0-or-nvme-or-sata-drivers

“A required CD\DVD drive device driver is missing. If you have a driver floppy disc, CD, DVD, or USB flash Drive, please insert it now. Note: If the Windows installation media is in the CD/DVD drive, you can safely remove it for this step.” This may be resolved by Loading SATA preinstallation drivers.

Note: This error message also shows if the installation .iso downloaded is incomplete/corrupt or the Bootable USB made is likewise corrupted. For this reason .iso checksums are present later on to reduce these chances.

Slipstreaming Drivers and Updates to your Windows Installation Media (Advanced)

Dell have updated only the Windows 7 Professional .wim file to January 2016. They have left the Home Basic, Home Premium and Ultimate Editions untouched from the 2010 Media Refresh. It is cumbersome but one can also slipstream updates to all the other Editions see my guide Slipstreaming PSP2, IE11, USB3.0 and NVMe into Windows 7 Installation Media.

OEM and Retail Licensing

OEM License

You should install the correct Edition of Windows 7 which matches your COA. To prevent the COA from fading the COA is likely residing in the battery compartment of Laptops and inside the computer cover of Desktops.

Laptop COA

If you are installing a non-Pro Edition you will be prompted to input your Product Key During Installation but it isn’t required:

activate

Instead of inputting a key Uncheck Automatically activate Windows when I’m online and select skip to initiate a 30 day trial. Complete the installation.

After the installation is complete you’ll need to activate Windows using OEM System Locked Preinstallation.

See here to activate using OEM SLP.

Retail and Retail Upgrade Licenses

If you are installing a non-Pro Edition you will be prompted to input your Product Key During Installation but may be rejected (especially if it is a Retail Upgrade Only Key):

activate

Instead of inputting a key Uncheck Automatically activate Windows when I’m online and select skip to initiate a 30 day trial. Complete the installation.

After the installation is complete you’ll need to remove the Dell Windows 7 Pro OEM SLP Key if you have installed Windows 7 Pro OEM.

Press the Start Button and in the search box type in CMD

Right click CMD.exe and select run as an administrator. This will open up the elevated command prompt accept any user account control prompt.
