Hi, I am Dave, I will help you with this.
That is a common problem if there is an Intel processor on the laptop, go to the support page for that laptop on the HP website, then from the chipset section, download the Intel RST driver installer.
Extract out the drivers from that installer into a new folder on the bootable USB you are using to install Windows, then when you reach the part where you cannot see the drive, click the option to load a driver from that new folder.
