Hi Leo Swart

Some ways to get back administrator access:

https://www.top-password.com/knowledge/r...

Are there any important data inside your PC? else if it fails, consider getting a live linux GUI CD to access your data.

Are they are Microsoft Windows 7 COA (Would like to check if the label is still intact and product key is visible) You need it later for Windows 10 fresh installation.

IMO I would prefer a fresh install of Windows 10 than a upgrade from windows 7.

As from experiences, some software and stuffs can mess them up.

Before you consider to do a clean installations, there are a couple of stuffs you need to do.

Get a thumbdrive, 8GB or larger.

Download windows 10 installer x64 from another pc with internet access.

https://www.microsoft.com/en-us/software...

Make the Win10 1803 USB

Boot up to your Lenovo BIOS page

Start PC and press F2 (Some might need to Press Fn + F2) to access

Set to Boot to OS Default, Enable secure boot.

Boot up the USB (F12 Boot Menu) (Some might need to Press Fn + F12) to invoke boot menu

Allow the installer to load.

If prompt for windows key, key in the Windows 7 COA into it, else if it is windows 8 sticker on your laptop, if it mention pro, select pro installation, else Home installation.

do a clean format, delete all partition and recreate again.

Remember to Update your laptop to the latest BIOS
