Windows 7: Replacing Windows 8 with 7 on OEM desktop?

Replacing Windows 8 with 7 on OEM desktop?

I have a full retail version of Windows 7 on my old computer on its last legs and want to install it on a new computer. I don't have time to build one from scratch and would like to get a new desktop computer from HP. I don't want Windows 8, so can I just replace the hard drive on the new computer and install Windows 7 on the OEM computer? Is there anything in the HP computer to prevent this installation?

You need a Windows retail license to do that. With an OEM license it will not work. And just swapping your old disk is not possible.

The new PC would be UEFI. That makes installing Windows 7 a bit iffy - but there are tutorials on this forum that tell you how to skin this cat.

Since you specified that you have a full retail copy of Win7, you of course can use it to UpDowngrade Windows 8 to Windows 7.

You can try the install first in UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums.

However if it gives you any trouble I wouldn't waste time with the added layer of crapware but instead Bypass UEFI to Install WIn7

Warning you must have the UEFI/BIOS firmware setting in Step Three set.

Make sure you read the NOTE at Step three.

As you are talking HP, you will need to use LEGACY mode.
