I'm having issues doing a clean install on this PC. It seems it comes with Windows 8 installed and another tech downgraded it to windows 7. I was then told to do a clean install on it and pulled the cd key with a program and installed Windows 7 Pro with a ISO I have. Now it won't activate the key saying it is invalid. I have the CDs coming from HP that I guess might help but I need this PC working today really. Is the key it pulled really a windows 8 key and just said 7 since that what was installed when I used the program to pull it? What are my options to get an active key?

Because the computer came pre-installed with Windows 8 the key is embedded in firmware. You can download the media creation tool here. You will need to download it using a Windows 7 or 8 computer.

 

Follow the clean install steps here. If you need data off the drive you can pull it using a live linux disk like FatDog64 or Hirens CD. You may need to disable SecureBoot in BIOS but I believe it has already been disabled if you are booting Windows 7. When you get to the Window asking for the Windows 8.1 key do not input anything and click Next. Windows 8.1 will self activate when online. 

 

If you cannot click next then use one of these generic keys depending on what version of 8 was on the computer.

 

Windows 8.1 (Not Pro): 334NH-RXG76-64THK-C7CKG-D3VPT 
Windows 8.1 Pro: XHQ8N-C3MCJ-RQXB6-WCHYG-C9WKB 

 

The key you pulled may be for Windows 7. You can verify it using this utility. When you input the key what is listed under Edition Type?

Getting this on "create media" link, of course it would be down when I need it >_>

Seems I have an ISO of Win8 Pro also, so I'm going to use Rufus to try a fresh install via it. Would have been greatly helpful to know this came with Windows 8 before hand, ha.

Looks like Microsoft want people to migrate to Windows 10. The Windows 10 media creation tool should  use the 8.1 embedded key but I am not sure if you want Windows 10. I will see if I can find the tool for 8.1

 

Edit: This link for 8.1 works with the above generic keys. Get it while you can because this link may go away soon too. Pick your key, Home or Pro depending on what was installed on your computer.

 

Posted on another forum that the media creation tool I linked to is dead. 

 

Edit Edit: Per your edited post. If your computer came preinstalled with Windows 8 and not Pro then using a Pro disk will not work. Use the above link to download 8.1 of your version.

That link isn't working for me either. I'm assuming it came with pro because it was downgraded to windows 7 Pro, and it is a business computer, we only use the pro versions for back office PCs.
