Cannot format Hard drive to completely install clean Windows

Hi,

I have a Viglen (Tesco's) Connect 10 tablet (Desktop-CTR0QB9). BIOS - american megatrends Ver 5.008. CPU - Intel Atom z3735G @ 1.33Ghz 32Bit with 64Bit support.

Was all up to date with V1709, Malwarebytes, Defender.

I was having a problem with the screen and touch pad uses, so I installed which I thought was the correct drivers for the tablet.
But it crashed with the Blue screen with'Driver Overran Buffer Stack' continuously looping trying to repair with not results. The only access to the system was via Command Prompt and despite doing what several people suggested to get back to life which all failed. Even could not access 'D: Recovery' or even using a USB Repair stick made sometime ago.

So I downloaded a Windows 10 ISO as I had nothing with the Tablet from Tesco's. Installed and prayed it not ask for a Product Key as I had none (tried 3 methods via CMD to retrieve). Although now I have a working tablet, but still have issues.

Several of the settings buttons/switches are Greyed and cannot be changed, and those which can be changed make no effect as it was set for.
IE: The tablet power button was assigned to shutdown, it don't'. Cannot get the Battery/Power icon on the tray, despite although greyed in the taskbar settings its switched on.

I have tried several times to reinstall Windows, Formatted the Primary partition, tried to remove unallocated partitions. Cannot either via windows or CMD using diskpart, only the installing lets it be done. I know its not a totally clean install as every time my Screen images load. The manufacture appears not to support for any BIOS updates only basic drv's.

So I want to totally clean the harddrive of everything and start again like new.

How.......
thanks

Should be no need to format if you're deleting the partitions in the install as in Steps 10 and onward in this Tutorial: Clean Install Windows 10

Are you saying the Windows installer will not delete partitions as described in the tutorial I linked?

Unless you are creating a bootable Windows install flash drive or CD/DVD and booting from that to do clean install, you are not doing a clean install. Did you execute Step 1, following the link to: Create Bootable USB Flash Drive to Install Windows 10 to create the install USB?

Yes as Step 1, as I had to properly format (not quick format) the USB before the 32Bit download would commence.

The only thing I do right or wrong, when doing the re-installs I go through troubleshooter to start the installation, not start the tablet with the USB plugged in ready to install.

The clean install, along with ability to remove all partitions, needs to be done booted to the installation media, per the Tutorial instructions. I've never done it by any other path and can't recommend an alternative to doing it as outlined in the tutorial.

You have to boot from the installer to delete all the partitions, if you don`t you are wasting your time Maybe the thing has a secure boot feature if it has some type of Bios, you need to disable that if it does.

"tried to remove unallocated partitions"

There is no such thing as an unallocated partition, only unallocated space.
