I got impatient and shut down my G50-80 while it was accepting changes after a windows update (not sure what update was for..it was taking so long and i needed to get work done on it).  I am now not able to get into windows and my desktop....keep getting lenovo logo, a fast blink of a white outlined box then the message that it is searching for a previous version of windows.  PLEASE HELP!!!!!! YIKES!! Thanks!!!

Hello Sluggo9

Thanks for using the Lenovo forums.


The warning is there for a reason, you don`t shut down your pc when its working on windows updates.

 

Sounds like that your installation has become corrupted.

 

You can try to revert back to the previous Windows update if you are able to or refresh. Power off the unit, and use the NOVO button to start it up.

 

See if this is able to help you out at all.

 

Hope this helps, let us know how you get on.

Thanks for your reply! I am unable to revert, fix or repair through bios and novo settings.  Microsoft suggested doing clean CUSTOM install of windows 10 which I will try to do, but do not want to loose any files ...I downloaded off their website onto USB and will give it a shot .....does this sound right before I do???? Thanks!!!!!

That would be the next step, but that will delete your data from the unit if you do a clean install.

No no, a clean install means exactly that. 

A CLEAN install, no files no software, it will be as a factory new unit, you cannot perform a clean install without deleting the old partitions and files.

 

It`s best to keep the recovery partition, but ideal to format the others to achieve clean install.

 

 

You could attempt to backup files before you begin the clean install, just follow these steps:

Any chance you could take a picture of your partitions?

 

Have you formatted them before attempting to install?

It sounds like there is multiple versions installed onto the hard drive. One option to back up data is remove the hard drive and use a working computer and usb hard drive adapter to pull of documents / files.
If this is sounding a bit much - find a friend that has computer skills, and ask for some help.

Once completed, have that same friend remove all non-recovery partitions, returning them to "un-allocated space"

Once completed, try re-installing the hardrive into the notebook and then install the OS from recovery or fresh install.
