G50-45 not working after Windows 10 update

2018-01-04, 20:52 PM

Good evening all and happy new year!

I have a G50-45 laptop that has run perfectly until this mandatory update and now I just get:

1) Lenovo Logo
2) White spinning wheel
3) What appears to be a command box but it vanishes
4) "Attempting to recover installation"
5) "Restoring your previous version of Windows"

And repeat..on loop.

Your help and advice is greatly appreciated, I am somewhat a n00b so please break it down to me in layman's terms, thank you so much and enjoy your evening.

Nick

Probably Secure Boot is enabled in BIOS - please disable it. Also enable boot from legacy devices.

By mandatory update you mean this week's 2018-01 Cumulative Update or Fall Creators Update?

Hi and thank you for your reply, being honest I can't recall the name but it started requesting this update several weeks ago and I kept hiding it or it would fail to finish.

Let's asume, it was a Fall Creator Update then. Probably upgrade has failed and your system is unable to boot. During major upgrades, Windows 10 allows to perform roolback to pevious version for a week after upgrade. In order to use this feature, you need to enter recovery mode. In my laptop, this is possible by pressin F11 key on Lenovo splash screen. In your case, this could be the same key or there might be a special button to display boot menu (or other way). You may try to use some of methods described below:

 

https://www.lifewire.com/how-to-access-advanced-startup-options-in-windows-10-or-8-2626229

 

Once you enter Recovery mode, go to Troubleshot -> Advanced Options -> Show more options -> Return to previous version. The path may similar (I don't remember exact words) or bit different as shown on link below:

 

https://answers.microsoft.com/en-us/windows/forum/windows_10-windows_install/how-to-recover-restore-your-previous-version-of/94368560-9c64-4387-92b9-82a9234216ad?auth=1

 

If this was really Fall Creator Update, then you should be able to restore your Windows installation.

You have OneKey recovery under Novo Button. Please don't use it, as it'll wipe your disk and restore your previous OS (Windows 8.1 probably). Let's try in different way then. Try to boot your OS and wait till it'll start "repairing" OS installation. At the end, there should be a summary on blue screen. Please use Advanced options button. Now you'll enter Windows 10 Recovery mode. At this point try to use steps described in my previous post.

I was worried that would happen. 

 

Thank you so much you've been very kind and helpful. I don't have my installation disks so I will ask a friend tomorrow. Last question, Do I need Windows 8 then or a different version?

 

You're awesome thank you!

It depends what you want to do. Using Novo/OneKey Recovery, you'll wipe your data and restore previous Windows version.

 

If you want to back to Windows 8/8.1, then use OneKey Recovery (you'll have to wipe OS partition anyway). You don't need Windows 8/8.1 to install/activate Windows 10.

 

If you want to reinstall Windows 10, download Windows Media Creation tool and use it to create USB Installation Media. Then again, you'll need to wipe your OS partition in order to reinstall Windows. And OneKey Recovery may or may not work any longer after it. Moreover, I believe, you can use it to run Windows 10 recovery.

 

If you want to get your data back, download some live Linux distro e.g. Ubuntu and create bootable USB media using Rufus. Boot from USB and select, that you want test/run Ubuntu. After it boots, connect a USB disk and make backups (or make it in cloud/NAS - whatever you preffer).

 

And finally, if you want to restore OS, to the way it was before update, you'll need to use Windows 10 recovery from your damaged installation, about which I've wrote before.
