Hard Discs not detected when installing RHEL 8.4

Hi there,

I just would like to do some experiences with RHEL 8.4 that why I am trying to install it on my HP laptop via boot USB.
The Problem I get is that the discs are not detected by the RHEL 8.4 installer.
I can only see the USB.
The same issue with a ThinPad Laptop.

Any feedback?

Thanks in advance
