Downgrading from Windows 10 Home to Windows 7 Pro

I sold 32 Lenovo Ideapads to a client already factory loaded with Windows 10 Home edition. They rejected all saying that their office only works with Windows 7 Pro. I tried to downgrade, but Microsoft does not allow downgrade for PC's that are factory installed
with Windows 10. The downgrade is only possible if one has upgraded from Windows 7 or Windows 8 to Windows 10 and later on (within a month) decide to go back to the previous versions.

I do not have the media CD's for Windows 7. Is there any other way one could downgrade. I am stuck with 32 computers! And i cannot seem to be able to procure computers with Windows 7 anymore.

Thanks in advance for a solution.

Unable to upgrade to W10,

The reset will install all the HP software as it was from the factory, so no pure Win 7 . I first had to restore / downgrade to Win 7 and then used the F11 key for the factory reset. If the Win 10 upgrade is not complete you can back though it will take
some time to clean up. The Windows and HP updates after the factory reset took hours so be prepared if you choose to do so.

 

The screen shot you posted shows the system restore page, not a factory reset page. There would be no system restore points to restore to because system restore was disabled.

 

You can try this: How do I recover my factory installed programs and files? - Desktops and Workstations - Lenovo Support (US)

 

That is because the upgrade created an extra partition and knocked out the link to the factory recovery partition...

from a command prompt (admin) Type and hit enter after each command below >

Diskpart
list disk
select disk 0
list partition
exit
reagent /info

Then Post a pic of the command prompt window
