Windows 7: how to uninstall windows 8.1 in order to install windows 7

Start by studying Downgrade Windows 8 to Windows 7.

You'll need to at the least disable Secure Boot on the BIOS tab in BIOS setup as pictured in tutorial, then boot the installation disk as a UEFI device, delete all partitions to see if that will reset the formatting to GPT, create your partitions as desired or just click Next to let the installer do it and begin.

Also look over these steps compiled to get a perfect Clean Reinstall Windows 7 which include everything that's worked best in tens of thousands of installs we've directly helped with here since beta. Over 1.3+ million consumers have used the tutorial without a single complaint and enjoy the best installs of Win7 one can have as long as they stick with those tools and methods.

Many thanks for your prompt reply Berton.
The appears to be answer is yes on comments.
1.) The windows 8 is a 32 Bit and my Windows 7 is 64 Bit but the PC can run on either. I prefer 64 Bit, So is it at all possible for me to convert the machine to run on 64 bit or has the installed OS permanently written the 32 bit system to some hardware?
2) Microsoft do not directly specify the OS to be OEM but I would assume this to be the case as it states "Licensed for distribution only with a new PC". Alas as I was hoping to save myself a few bucks here.
Obviously it would now be preferable to install Windows 10.

1. No easy way to change to 64-bit without doing the clean install.
2. Yes, that description has been for OEM versions for a number of years starting at least with Windows 95 [1995] when the software was distributed on CD and had room for the printing of it. It's also spelled out in the EULA/End User License Agreement.

For Win10 the 32-bit versus 64-bit part will still apply.

You would follow Clean Reinstall Windows 7 to get and keep a perfect install, just like over 1.3 million other average consumers have without a single problem or complaint. You will have the best install of Win7 possible.

There is no concern whatsoever about switching from 32-bit to 64-bit, and you should if you have more than 3gb RAM on the PC.

If the license you own is retail Builder's OEM then it's still possible MS will allow activation when using the telephone option after it fails, as we have had repeated reports that these rules have been loosened once Win7 only became available in OEM version. If not, you can buy another license to insert the key for that version (Tiger Direct is regularly $89) or immediately upgrade to Windows 10.

Many thanks Berton and gregrocker.
Wow now I have something to "chew on"
Yes first bet is to establish what version I have which I registered was registered with MS after installation and then negotiate a license if it is not a retail version and install into my Veriton and then apply to convert to Windows 10.
The only remaining problem being that I am presently unable to source either the original windows 8.1 disc or in fact even the access password as my sister is not contactable at present. So there could be some delay for a month or so prior to my being able to correctly clear and prepare the HDD.
