Formatting an HP notebook

[TI33]

Good morning,

I have an HP model: HP 256 G8 / SN: BRM3498JB5
I need to format this notebook using a bootable USB drive, 
but the partitions don't appear so they can be formatted. 
Where do I enable the option to make the partitions visible so they can be formatted and new partitions 
installed?

To make partitions visible during formatting from a bootable USB (likely Windows installer), load the Intel Rapid Storage Technology (RST) driver at the "Where do you want to install Windows?" screen, as this model uses Intel storage controllers not natively detected by Windows setup. IRST driver should be available on hp driver page of your laptop. Get that and extract it in your bootable USB. 

Then to Load Storage Driver: 

In Windows Setup, when no drives/partitions show:

- Click Load driver > Browse to your USB.

- Select the compatible Intel RST driver folder (e.g., iaStorAC.inf); partitions will appear.

Format and install as needed.  I just suggest to delete windows driver and it's partition then install windows on unallocated space.

Hi, @TI33 

Since all of the Intel storage controller drivers are in exe format, you need to extract the exe file into its driver folder.

I have done that work for you below and attached the driver file that should allow Windows to find the drive.

Another option is to use the HP cloud recovery tool to create a bootable USB recovery drive to restore the HP factory software image.

Here is an info link for how to use the utility:
