I recently bought a used Dell OptiPlex 7060 that was refurbished for business use. Initially, everything was working great, but then the computer unexpectedly shut down and wouldn't start again. After some troubleshooting, I discovered that the SSD had failed, so I replaced it and created a USB drive to do a clean Windows installation. However, I hit a snag when Windows prompted me to sign in with a Microsoft work or school account. The issue is that this account is tied to the original company that owned the PC before it was sold to a leasing reseller, and then to me. I believe the device is still registered in Azure Active Directory or Microsoft Intune under that original company, causing this complication during installation. I'm looking for help with a few questions: Is this an Azure AD or Intune lock? What options do I have now? Does the original company or reseller need to remove the device from their account? Can I do anything myself, or is this strictly an administrative issue? I do have proof of purchase from the reseller, but I don't have access to the original company's Microsoft tenant. Any advice would be greatly appreciated!

Try reinstalling Windows, but make sure you don’t connect to any network during the process. When you reach the initial screen, press Shift + F10 to open a command prompt, then type 'oobebypassnro' and restart. Just continue setting it up without connecting to the internet. However, be aware that if the device is enrolled in Intune, it will revert to the company account the moment it connects to the internet.
Yes, you have it right; the original company or admin who enrolled the computer will need to remove it from Intune or the software they used. If you want to avoid this issue, you could try installing a Linux distribution if the BIOS isn’t locked.
