Fresh Windows Install : Won't detect drive !

I have a E6320.

I want to do a fresh install of Windows 10.

At the Custom Installation window, it won't detect the HDD for install ... BUT ! If I try to load drivers, I CAN SEE THE C: drive !

I have tried to loads defaults from BIOS : won't work
I have tried the following SATA configuration : ATA, AHCI and Raid On. None works
I have tried to boot USB Key (Win10 install) from either Legacy Boot or UEFI

I have tried to load some drivers but none works ?

WTF is this ???

 

Oh well, for what it's worth, this solved my problem :

Boot with Win10 USB Key, Go to Repair PC > Advanced > Command Prompt

>diskpart [enter]
>list disk [enter]
From the list above (assuming you have more than one HD installed, if not it'll be the only one), find the number corresponding to your HD.
>select drive [number] [enter]
>clean all [enter] * see note below
>create partition primary [enter]
>select partition 1 [enter]
>active [enter]
>format fs=ntfs [enter] ** see note
>assign [enter]
>exit [enter]
>exit [enter]

Rebooted and it detected the drive !
