Lenovo Ideapad Z575 Upgrading & Downgrading - Mssing Drivers

[Gregrs]

I have a Lenovo Ideapad Z575 laptop with windows 7 pre installed on it. With the realse of windows 8, I decided to upgrade from windows 7 to windows 8. That was a big mistake; So, I wen't from windows 8 back down to windows 7. I didn't notice this until after I setup my computer but the windows 7 drivers got deleted and they were replaced with nothing. Because this is a Lenovo brand computer, it has a program called onekey recover. So I installed that through a USB becuase the laptop doesn't have a LAN wireless network connection driver on it. And I don't have internet at my house. So anyways, once that was installed, I ran it and it didn't work. Is there anyway I can restore all of my drivers and use the lenovo onekey recovery?

You will have to download the drivers from Lenovo. Generally, Windows 7 will install many drivers, although it may not install all.

You will have to download all the drivers from Lenovo for the Z525. Start with the video, Sound, Ethernet, Wi-Fi, touchpad, etc.

Once a different OS was installed on the PC, I don't think the Onekey or any recovery partition will work. Only a manual install with a Windows disc and all the drivers.

I have an Indeapad Z560.

Could I just install the BIOS and the Recovery drivers and run onekey recovery? Or would I have to install them all?

You don't need the BIOS. Just all the other drivers, and any optional software that you want.

The onekey assumes you have everything on the recovery partition of the hard drive. I doubt that anything is there since you installed Windows 8 and then reinstalled Windows 7. The onekey sounds great but I would just forget about that and install what is needed manually.

I installed ALL of the lenovo drivers and I tried to run onekey recovery again with no luck. I just got a windows 7 installation CD from a friend of mine, If I use that, will it re-install all of the windows 7 drivers so I may use lenovo onekey recovery?

As noted the onekey WILL NOT work with your system since its been upgraded and now downgraded. Forget onekey.

As far as a friends Win 7 installation CD, that copy is already activated. You can't activate it again, unless its a multi-PC version that has not been activated on the number of PC's that it is set up for.

If you don't have or did not make the backup copy when you got the PC, you will have to purchase a legal copy.

 

[Gregrs]

Its one of those CD's where it can work on multiple computers because I've used it multiple times already, it just asks you for a key when it loads...

You can try a "clean" install with that Windows DVD and see what happens. Make sure you are connected to the internet so Windows can get what it needs.

A "clean" install involves reformatting the hard drive first then install Windows.

After Windows 7 is installed you will probably still need some drivers. e.g. Windows will install the sound (assuming there is no hardware problem and its enabled in the BIOS), the "HD Audio Codec", but that is only a basic function sound driver, for full functionality you need the Lenovo driver. Windows many not install the drivers for the touchpad, built in web cam, etc.

All of the lenovo drivers are installed now. I can play my games and I can use areo themes and stuff like that. The only problem now is the OneKey Recovery. I know you said to forget about it, but I can't. When I run it, it just goes back to the login screen and I log on. It doesn't go into the system recovery environment. What kind of windows 7 drivers am I missing that makes onekey work correctly? Is there a program I could use to detect missing drivers?

HI Gregrs
Maybe you can try a workaround known as OKR 7.0 Engineering edition. Please refer to the following link here....
