Downgrade G50-45 (80E3) to Windows 7 Pro 64 bit

Can't stand W8 or W10 would like to go to W7 Pro 64 bit.  The drivers are on the website, but I am unfamilar with the (new to me) UEFI boot process. I have installed W7 on desk tops and laptops, so that I understand, it is just the UEFI boot has me concerned.

 

Would I have to change the BIOS or just set it to Legacy and everything would be normal?

In case this doesn't work I do not need a boat anchor or plant stand. :-)

 

Hopefully I am not asking the same question that has already been answered and I didn't find it.

 

Thanks, Fred

Hi FredY42 , 

 

 

Welcome to the Community Forums. 

 

You have the idea needed to install Window 7 , but beore you do that best that you back up all your files and create yourself your recovery media for future use .

 

Just turn off and turn on the pc using the Novo button (item2 page 9).

Choose BIOS set up to from the Novo Menu.  

Usual setting  Boot mode to legacy / EFI  , CSM enableb , Secure boot disabled .

If on the exit tab , you see option for OS optimized to Windows 8 , just change it to "other OS" and save and exit.

Would you be planning on a clean install ? This would remove the hidden partition intended for full factory reset .

 

reference for review:

How to Install Windows 7 Using the "Unified Extensible Firmware Interface" (UEFI)

Creating Windows UEFI Boot-Stick in Windows

 

If you have a spare harddrive to try it first without risking the original image.

 

Update us how it goes.

 

 

Regards

Yes I am using a new SSD to do everything on, so I don't lose anything. Load  W7 SP-1, install all the updates, transfer all the personal files and do an image copy of the new drive also. Already did one of the "as shipped hard drive", for safe keeping also.

 

Thanks for the other links. Sorry I missed them. Will report back when I have completed the task. It will be later next week off to have some fun.

 

Thank you, Fred

Hi FredY42 , 

 

Good that we have a blank SSD to proceed with a full install of Win 7 pro SP1 64 bit.

Before change the BIOS setting , you may try tapping on F12 for the boot manager if that you normally allow installation.  Else reconfigure BIOS as noted above. If that fails then proceed with the link guides.

Enjoy the weekends off and just update us after .

 

Regards

Thanks and I'll give the F12 key a try. The few times I went in before I used the Lenovo button.

It did not work, since Lenovo does not have all the Windows 7 drivers for the machine. I gave up and left it at Windows 10. It has some many little annoying problems, but at least the WiFi will work, which did not under Windows 7.

Hi FredY42 , 

 

As the machine was originally set for Windows 10 and Microsoft would soon be doing succeeding patches soon.

Hope those small things found alternate ways to work around them for now.

 

Please free free to visit our community at any time both for your query and sharing ideas with fellow members .

Goodluck on all your endeavors. 

 

Regards

IMO, both 8 & 10 are entirely worthless to us, the users, and only function to generate revenue for MS. Furthermore they waste the entire communities time by forcing everyone to write more drivers to stay current. 

 

Writing eye-candy is a mindless, yet very profitable, endeavor for the world at large. Cleaning up all the security flaws would benefit everybody, not generating more open doors for thieves and rouge nations to hack each other. 

 

Yes, this is a rant against MS. I am so tired of wasting my time getting around their lunacy.
