The drive can be cleaned using diskpart.
In case the drive is not GPT and you want GPT:
diskpart
List disk
select disk 0 (make sure disk 0 is where you want to install Windows, check twice)
clean
Convert gpt (if required for UEFI)
exit
exit
Proceed with install and let Windows create partitions it needs.
tried the "clean" option last night but wouldn't let me do it - can't remember the wording that came back on cmd prompt
Another options if the drive is easily removed is to place it in a hard drive bay of another computer or into a hard drive enclosure.
Then you can run the clean option using diskpart.
I will re-try the clean install and see if any options to delete/format comes up - if not maybe try the HD into a different PC and see if I can do it that way.
I'll still post a pic of the disk partitions tonight before I attempt anything.
Thanks for your help btw
If you use the installer and go to command prompt, you should have no problem using Diskpart from there.
If you boot into the installer and hold Shift then press F10, you will get a cmd prompt. Alternatively when you get to the window of where do you want to install, you can highlight each partition and press delete to delete all partitions.
when you say boot into the installer do you mean when I boot into the Win10 install DVD ??
Boot into my Rescue Media...
Then use aomie partition assistant to Copy/clone the D;/ partition to the C:/ partition
Then delete the D:/ partition
OR Even better...
just wipe both drives, format the D:/ Drive and then run setup.exe from the mounted windows 10 ISO
selecting the unallocated Drive as the installation drive..
Yes. You will see this screen
Highlight each partition one at a time and click delete. until it shows as unallocated like in the screenshot.
