Windows 10: Installing: Windows can't be installed on this drive.

Hi Windows peeps.

I've got the job of reloading Windows on my girl's computer, and I'm running into a problem installing it via USB.

I formatted the HDD, before finding out that the laptop possibly had drivers on it already.

Now I'm presented with the Windows installation asking "Where do you want to install Windows?", however the only drive listed is "Drive 0 Unallocated Space", with a total size of 0MB and 0MB of free space.

An error is shown - Windows can't be installed on this drive - with detailed information saying:
"This partition is too small. Make the size of this partition at least 12327MB or select another partition.

Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the BIOS menu."

I've looked at the BIOS (which is InsydH20 and offers very few options) and there is nothing labelled "Disk Controller" or similar that can be changed.

My understanding to this point is that I need to pre-load the driver for the laptop's funky drive (Acer Aspire ES 15, product number ES1-523-41EW).

Clicking "Load driver" and selecting the IO driver I downloaded from Acer's website (Product support) returns me to the "Where do you want to intsall Windows" screen, this time showing no drives at all.

I'm hoping the community could point me in the right direction to get Windows recognizing the HDD and proceeding with the install.

Thanks for helping!
