Problems while installing qubes on a usb

I am trying to install qubes 4.1 on a usb on a
lenovo carbon x1 5th Gen i7-6600U with Intel® HD Graphics 520

I have downloaded the iso and verified it

I plug in the install usb and the destination usb and boot

The installer starts fine

There are two problems:

  1. On the software selection window, I dont have debian and whonix options, only “qubes ui (audio/gui)” is available
  2. On the installation destination window, only my hard drive is shown, my destination usb is not shown. I tried to refresh to no avail.
