Second hand laptop. Invalid windows upgrade. Unable to access OEM recovery for laptop.

[KidComics]

I recently purchased a second hand HP 2000. When i went to reset the PC I discovered that the windows 10 upgrade was not authorized/activated. I have been trying to revert to the original operating system (Windows 😎 but F11 will not access the OEM drive. The OEM drive shows as being full but I am not able to see the files. Can anyone help me get this PC back to its original system?

Hi:

Here's how you can reinstall W8.1 by using the W8 product key in your notebook's BIOS.

Install W8.1 by creating the Microsoft installation media, using another Windows PC, if yours is not working...You want W8.1 64 bit.

If you are asked to enter a product key during the installation process, use this generic key.

This is the generic key for W8.1 'Standard.'

When you get to the screen that asks 'Where do you want to install Windows,' delete every partition on the hard drive, leaving just one partition of unallocated space. Click Next, and W8.1 should begin to install.

If you had to enter the generic key, manually change the generic product key to the W8 key in your PC's BIOS in the PC settings menu.

After you get W8.1 installed, and you had to manually enter the W8.1 generic product key, you will need to run the free utility I zipped up and attached below, that will show you show the W8 product key in your PC's BIOS.

I have also zipped up and attached below, the Microsoft tool which hopefully will transfer the ISO file to a DVD or USB flash drive so it is bootable, or you can use a different free utility such as Rufus or burn the ISO file to a DVD with another DVD burning program.

Then you can install the available drivers and software from your PC's support page.

Thank you for the information. I am working on this as I type. The first time through I downloaded the Single Language edition of Win 8.1 and it told me that the key did not match any of the available editions to be installed. I am currently downloading the basic edition. I will update you again once I find out if the "standard" key works for the install.

You're very welcome.

If the notebook was sold in the USA, it would have come with the standard version of W8.

The single language versions are sold overseas.
