Phemo Ah ah! Aproko Phemo, I have solution to your problem, your laptop was “autopiloted”.
Let me explain it so that you and other can know about it. Autopilot is a product on Windows Intune, it helps organisation in provisioning and management of devices in their organisation. This process helps reduce the time and effort required for IT administrators to set up and maintain Windows devices, especially in scenarios where the organisation provide new devices or need to reset and repurpose existing ones to their staffs.
Its a good thing you already mentioned that its from a company your seller used to work. I would have suggested you reach out to the IT admin of the company, but they just might not know what to do else they would have removed the device from their network since it was auctioned. So, here is the solution;
The Login screen comes up because you have to connect to the internet during setup and once that happens the autopilot finds the device. So, the solution is to setup the device without connecting to the internet, so you need to open the command prompt with (Shift + F10) and type OOBE\BYPASSNRO. Then you would be able to create a local account.
The second option is to create the Windows bootable ISO using Rufus, and select “setup local account” option on one of the popup screens. And your setup would be smooth.
That should solve your problem. Dont forget to report with your thanks giving offering. @aprokodaddy am I talking? lol
