Product Name: Compaq Presario CQ5207SC

Operating System: Microsoft Windows 7 (64-bit)

---

I need help to install an operating system on my old desktop. It didn't run Windows 10 very good so I tried to degrade it back to Windows 7. Apparently it failed, and had also somehow deleted the Windows 10 operating system. So now I'm left with no installation disc (I lost it), and no operating system. Where can I get the OS, and how? Also, how can I boot the installation from CD or flash-drive? Tell me if you need serial number, product key etc.

Thanks in advance

-Anton

@ AntonR

 

If you have access to another working Windows computer, you can download the 2.4GB(32bit) Win 7 SP1 iso  and burn it to a DVD+R or USB-stick, eg with the Imgburn or Universal USB Installer program, and then do a reinstall. .......

You can also order online from HP's website for your Win 7 Install/Recovery DVD which will cost you about US$20, including shipping.

 

Since the Win 10 digital license is already registered on your motherboard, you should also create a Win 10 Install media via M$'s website, as another option.

You will want to exercise caution when downloading ISOs from non-Microsoft websites. Heidoc appears to have a good rep, but there's no guarantee the ISOs you are getting aren't tampered. You would be safer going with the HP option.
