Hi there and welcome
If the factory image has not been removed Neil it will be possible to return to the factory image.
To do this, power off the Notebook
Then power it on and keep tapping F10 until you get to the recovery manager
If you do not, use F11
Once there, follow the onscreen instructions and perform a factory reset which will return it to new (wiping all data) working order with windows installed.
If you have any problems, or would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
Hello and thank you for your question. Please let me know if you still require assistance and I would be happy to continue working with you.
Can you tell me please what happened when you attempted Richard's suggestion?
