Hi everyone.. I've got a Lenovo B320 all in one idea centre that I'm currently selling and need to restore to the factory image (Windows 7 home premium 64bit) however with the great hoo haa that Windows 10 caused I had previously installed the update but swiftly uninstalled soon after.
Now due to that it has rendered the Lenovo restore partition (F11) useless and when I do manage to get access to the hidden partition via command prompt I can start setup but it then asks for drivers (which should be on the HDD or drivers disk I have) but will not recognise either areas and therefore cannot progress.

I reinstalled Windows 10 to hopefully do a new install procedure but it's an issue as There is no working Windows 10 Bluetooth driver and now means the Bluetooth keyboard and mouse is now useless...

I was hoping to download a Lenovo Windows 7 oem but cannot find one and now just want to put a brick through the bloody thing!!

Any suggestions of how I can restore to factory and hopefully sell it on?

Thanks in advance!
