Introduction

Dell Intel-Based Hardware is always on the advance.

Dell use the name 3xxx (good), 5xxx (very good), 7xxx (excellent) and 9xxx (Xtreme Performance System) to determine the grade of systems within the following product ranges; OptiPlex Desktops, Vostro Desktops, Inspiron Desktops, XPS Laptops, Latitude Laptops, Vostro Laptops and Inspiron Laptops.

Likewise Intel utilise the names i3 (good), i5 (very good) and i7 (excellent) processors. One can gauge the age of their hardware by looking at their processor model number. I’ll demonstrate this using a few example models:

  • Westmere – 1st Generation e.g. i7-860 (XPS 8100 Early 2010) – SATA2 – USB 2.0 – Legacy BIOS
  • Sandy Bridge – 2nd Generation e.g. i7-2600 (XPS 8300 Early 2011) – SATA2 & SATA3 – USB 2.0 – Legacy BIOS
  • Ivy Bridge – 3rd Generation e.g. i7-3770 (XPS 8500 Mid 2012) – SATA3 & mSATA – USB 2.0 & USB 3.0 – UEFI BIOS
  • Haswell – 4th generation e.g. i7-4770 (XPS 8700 Mid 2013) – SATA3 & mSATA – USB 3.0 – UEFI BIOS
  • Broadwell – 5th generation e.g. i7-5500 (XPS 13 9343 Early 2015) – NVMe & USB 3.0 – UEFI BIOS
  • Skylake – 6th generation e.g. i7-6700 (XPS 8900 Mid 2015 & XPS 8910 Mid 2016) SATA3 & NVMe – USB 3.1 – UEFI BIOS
  • Kaby Lake – 7th generation. These are just coming out however they are released after the 31/10/2016 which was the End of Windows 7 OEM sales. It is likely and somewhat ironic that the 7th generation i7 will not support Windows 7.

Needless to say Microsoft don’t follow Dell or Intel’s Logical Numbering Scheme with the exception to Windows 7 being one of their best Operating Systems of all time. They have instead; Windows Vista (Poor), Windows 7 (Excellent), Windows 8 (Abysmal), Windows 8.1 (Acceptable with Minor Annoyances) and Windows 10 (Excellent).

As hardware advances newer drivers are needed in order for Windows to recognise and utilise input devices and recognise the storage controller to copy Windows Installation Files to the HDD/SSD and Later Load Windows. Microsoft have been way behind the times and failed to update their Windows 7 Installation Media in accordance to Intel 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 If one tries to use outdated installation media on a modern system the mouse and keyboard may not be responsive on the first screen because no USB 3.0 drivers are present: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

If one manages to get by this screen by use of a USB 2.0 port or Laptop Touchpad/Keyboard (or have USB 3.0 drivers included in their installation media). They may reach an additional hurdle and get 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 or slipstreaming them into the Windows Installation Media.

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.

Microsoft have however rectified these mistake with Windows 10. Windows 10 Installation Media will be updated in accordance to Intel hardware releases. For more details about your Windows 10 Free Upgrade see Download Windows 10 OEM and Retail .iso.

If you aren’t ready for Windows 10 yet you should note that the last official Windows 7 SP1 Media Refresh .iso was released in 2011! As the Windows 7 Installation Media that Microsoft Provide is severely outdated. Dell released a Windows 7 64 Bit Professional .iso for 6th Generation Intel Skylake systems with additional driver support in particular NVMe and USB 3.1. This includes Internet Explorer 11 and is updated to January 2016.

dell-windows-7-reinstalaltion-dvd31

Dell unfortunately don’t provide a .iso for 1st-5th generation Intel systems so I slipstreamed updates until June 2016 to my set of Dell Windows 7 Reinstallation DVDs. These Unofficial .isos should work on all earlier Dell systems Dell sold with Windows 7 OEM.

Dell Windows 7 Reinstalaltion DVD3

The 6th generation Skylake .isos should have the USB 3.1, SATA preinstallation drivers and NVMe updates required for Skylake systems to install using the Advanced Host Controller Interface (AHCI) SATA operation. The 1st-5th generation .isos should have the USB 3.0, SATA preinstallation drivers and NVMe updates (64 Bit only) required for most systems to install using the AHCI SATA Operation. Additional SATA drivers may be required when using other SATA operations such as the Intel Rapid Response Technology (IRST) which was used for systems with low capacity SSD mSATA cache drives. If you aren’t using AHCI and need to prepare and load SATA drivers see my Downloading, Preparing and Loading SATA Preinstallation drivers guide.

It is possible that new NVMe SSDs released in Late 2016 or later will not be recognised by Skylake Windows 7 Installation Media as they will lack SATA preinstallation drivers. At this time Windows 7 will have reached End of OEM sales so the necessary drivers may not be created by OEMs.

All Dell Windows 7 Reinstallation .isos in this guide will apply Dell OEM System Locked Preinstallation. This is an automatic Offline Dell BIOS based activation mechanism. The key on the COA is not needed for this type of activation:

Windows 7 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.

New UEFI Systems may utilise OEM Downgrade Rights. The Dell Windows 7 Professional Reinstallation .iso will activate on Dell systems sold with Windows 10 Pro or Windows 8.1 Pro:

win10Pro Win8Pro

Official Dell Windows 7 Reinstallation .isos for 6th Generation Skylake Systems Only

A list of Dell Skylake Systems are here. This list should also include the XPS systems such as the XPS 8900, XPS 8910 and XPS 13 9350.

As Windows 7 has reached End of OEM Sales typically only Windows 7 Professional Licenses are sold with these systems and this utilises downgrade rights from Windows 10 Pro or Windows 8.1 Pro. 64 Bit Windows is standard.

  • There are hence no Windows 7 Home Premium or Windows 7 Ultimate .isos available for Download.
  • Modern systems will not have any 32 Bit drivers hence there is no 32 Bit Skylake .iso available for Download. There appears to be a 32 Bit Skylake .iso but I don’t have it to hand and so have limited details on it.

The Skylake .iso image is available to Download Officially if and only if you ordered your new Dell system with Windows 7 Professional Preinstalled.

There appear to be multiple different Skylake .isos depending on your region.

The first is Windows 7 Professional 64 Bit English only:

  • WGC5Y_2FR1DA00_W7SP1PRO64_ENG.iso

english-only

This .iso has 192 updates included with the latest update being KB3124001. Since this update was released on Jan 12 2016 we can call this the Dell Windows 7 Professional English Only January 2016 Skylake .iso.

The second is Windows 7 Profession 64 Bit Multi-Language:

  • G13K9_PW4KGA00_W7SP1PRO64_ROW(DL).iso

win7alllang

This .iso has 192 updates included with the latest update being KB3124001. Since this update was released on Jan 12 2016 we can call this the Dell Windows 7 Professional Multi-Language January 2016 Skylake .iso.

The checksums can be checked with Rufus (which we will use later to make the Bootable USB):

https://rufus.akeo.ie/

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

rufus

Select yes at the user account control prompt.

Unofficial Dell Windows 7 Reinstallation .isos for 6th Generation Skylake Systems Only

Unofficially the November 2015 Multi-Language Skylake .iso is available here:

Unofficial Dell Windows 7 Reinstallation .isos for Intel 1st-5th Generation Models

I have invested quite a bit of time into procuring a full set of Dell Windows Reinstallation DVDs and due to the tedious procedure of updating a fresh Windows 7 Clean Installation spent quite a while in Slipstreaming Updates. I have thus created 6 Dell Windows 7 SP2 Reinstallation .isos. These can be considered Sep 2016 Media Refresh and utilised the Intel USB 3.0 Creator version 3. A Clean Installation e.g. with the Windows 7 Pro 64 Bit .iso comes with a large number of updates which significantly reduces the time taking for installation and updating:

win7sep2016preinstalledupdates

The same languages are available as the Skylake .isos. The .isos may be found unofficially here:

https://drive.google.com/folderview?id=0B7uwifuW-47rd2o5N1BFVm5jYWc&usp=sharing

These .isos will not work with Intel 6th Generation Skylake systems as there is no Intel USB 3.1 USB Creator Utility and there are newer SATA Preinstallation drivers missing. Also at present I don’t have a Skylake system to test with.

The file sizes of the .isos are as follows and they have been updated to include Windows 7 Service Pack 2 and Internet Explorer 11.

Before using the .iso you should check that it has fully downloaded. The file size should match the following:

The checksums can be checked with Rufus (which we will use later to make the Bootable USB):

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

Select yes at the user account control prompt.

Creating a Bootable USB

You will require a 16 GB USB Flash Drive. A DVD is not suitable as it is too small.

Use Rufus to create a Bootable USB:

Once you have the .iso and Rufus downloaded, launch Rufus:

win7sp2b

Select yes at the user account control prompt.

The order in which you use Rufus is very important…

FAILURE TO USE RUFUS IN THE CORRECT ORDER MAY RESULT IN THE WRONG TYPE OF BOOTABLE USB BEING CREATED.

To the top select your USB Device, it must be 8-16 GB.

2

Next although its at the bottom you must load the .iso:

3

Select the .iso you wish to make a Bootable USB from and select open:

4

For a UEFI BIOS you should select the partition scheme as “GPT partition scheme for UEFI”:

5

Select the Partition Scheme and Target System Type as “GPT partition scheme for UEFI” because the install.wim of the updated Windows SP2 64 Bit .isos is greater than 4 GB NTFS will automatically be selected instead of FAT32.

Rufus USB GPT NTFS

For a system without a UEFI BIOS and/or for the Installation of 32 Bit Windows use the MBR Partition Scheme for Legacy BIOS.

Once you have the correct settings select Start:

8

Select Ok to acknowledge that you are going to format the USB flash drive:

9

Rufus will now make the installation media.

10

Once its completed the task, the progress bar will be full and it will say Ready below it. You can now close Rufus. You have your Windows 7 Service Pack 2 Reinstallation USB prepared:

11

Notes on UEFI

In the UEFI BIOS setup.

  • SecureBoot must Disabled.
  • Legacy ROMs must be Enabled.

For more details see Unified Extensive Firmware Interface.

Windows 7 will be setup to be installed using a UEFI Boot.

Installation Instructions

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

Notes on Windows Update

Windows Update for Windows 7 has been broken for several months and you will waste many hours searching for Updates. Use the WSUS Offline Update to fully patch Windows 7 after installation. Windows Update will work after WSUS Offline Update has fully updated the Windows 7 Installation.
