Install Windows 7 on a G70-80 which had Windows 10

The following is a step by step procedure for Installing Windows 7 on a G70-80 (purchased April 2016)

You will need to purchase a Windows 7 disk and do a "clean install"

I also bought a new hard-disk so I just change hard-disks if I want to easily return to Windows 10.

 

Computer Bios changes

1) Set the BIOS for Legacy mode, Set the BIOS to give Legacy mode first priority

2) At the Boot Manager screen select boot from DVD (the windows 7 DVD)

 

Installing Windows 7 drivers

 

3) After Installation of Win 7 is complete
Only Install driver for wireless network card..
WLAN Driver (Atheros, Realtek, Broadcom, Intel) for Windows 7 (64-bit)

4) Get upates from Microsoft update site
5) Only Install Win7 critical updates (Do NOT install security or optional updates yet)
6) Verify that that update KB2685811 (Update for Framework Version 1.11) was installed
If it was not installed it can be downloaded fom Microsoft website as an executable file.
7) Reboot computer after installing updates

 

8) Install Win7 drivers in this order

9) The Microsoft .NET Framework 4.5. MUST be installed first

10) Framework .Net 4.5 for Windows 7 (64-bit)
11) Intel Chipset Driver for Windows 7 (64-bit)
12) Intel Management Engine Interface Driver for Windows 7 (64-bit)
13) Intel Rapid Storage Technology (IRST) Driver for Windows 7 (64-bit)
12) Intel IRST Patch
13) Intel USB3.0 Driver for Windows 7 (64-bit)
14) Audio Driver for Windows 7 (64-bit)
15) LAN Driver for Windows 7 (64-bit)
16) Bluetooth Driver (Atheros, Realtek, Broadcom, Intel) for Windows 7 (64-bit)
17) Card Reader Driver for Windows 7 (64-bit)
18) Touchpad Driver (Elan, Synaptics) for Windows 7 (64-bit)
19) Intel VGA Driver for Windows 7 (64-bit)
If you have the Nvidia high resolution video card then install
Nvidia VGA Driver for Windows 7 (64-bit)

20) Camera Driver (AVC, Bison, AWA, Liteon) for Windows 7 (64-bit)

21) Lenovo Energy Manager (ACPI Power Controller)

22) BACK-UP the hard-drive , just in case the remaining Microsoft updates give you problems

23) Install the Microsoft security updates

Very helpful, but the driver for the ACPI Controller for Windows 7 appears to be missing for the G70-80.  Anyone know where to find it?
