Is it possible to install QubesOS without any sort of external media and 1 drive?

No, an installation medium is required:

Installation guide

Once the ISO has been verified as authentic, you should copy it onto the installation medium of your choice, such as a USB drive, dual-layer DVD, or Blu-ray disc. The size of each Qubes ISO is available on the downloads page by hovering over the download button. The instructions below assume you’ve chosen a USB drive as your medium. If you’ve chosen a different medium, please adapt the instructions accordingly.
