Introduction

The last official Windows 7 .iso released by Microsoft was the Windows 7 SP1 Media Refresh 2011 Commercial OEM and Retail .iso. Its heavily outdated and Installation will Fail due to the lack of native driver support for USB 3.0 ports and Storage Controllers.

To alleviate these issues Dell released a Windows 7 64 Bit .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.

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

Installation .iso Checksums

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

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.

Because the .iso is only available as a direct download and no checks are made to ensure the .iso integrity is intact the .iso checksums should be verified. They 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.

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 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 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.

3

Select the load .iso icon:

Select your .iso and select open:

For a UEFI system ensure the partition scheme is GPT for UEFI is selected and the file system is NTFS.

For a Legacy system 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.

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.

Notes on Windows Update

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. For a single install however it’s easier just to install the following updates…

Windows 7 Professional

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:

Dell Intel-Based Hardware

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 and look at the BIOS type, USB type and storage controller type:

  • 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 e.g. i7-7700 (XPS 8920 Early 2017). These 7th generation i7 processors will ironically not support Windows 7. For more details see No Microsoft Windows Operating System support for Intel Kaby Lake Processors. The only way to install Windows 7 on 7th generation Intel Hardware and newer is via virtualisation for more details see Notes on Installing Windows 7 as a VM on 7th Generation Intel Hardware.

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).

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

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.

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.

It is possible that new NVMe SSDs released in 2017 or later will not be recognised by Skylake Windows 7 Installation Media as they will lack SATA preinstallation drivers. Windows 7 has reached End of OEM sales so the necessary drivers for newer hardware may not be created by OEMs.

Dell OEM Licensing and Downgrade Rights

The Dell Windows 7 Skylake 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.

Laptop COA

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

win10Pro Win8Pro

Downgrade Rights on 7th Generation Intel Hardware and Newer

You will be unable to install Windows 7 Pro OEM natively on 7th Generation Hardware due to the lack of drivers for newer hardware. However system’s with 7th generation processors are extremely capable of virtualisation.

The Windows 7 Pro System Licensed Internal Code (SLIC) 2.1 can however 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.

Use the Dell Windows 7 Pro Reinstallation April 2017 .iso from above for installation media.
