When you re-run an instllation, then stop at/before partitioning, and
use Ctrl-Alt-F2 to enter a shell "in" the installer.

Then do: df -h
to verify that "/cdrom" is a mount point of "/dev/sd.1" (where . is
the character [a-q] that identifies the SATA adapter for the USB)

Then do: ls -l /cdrom/.disk
to verify that the info file exists.

Then do: cat /cdrom/.disk/info
to verify that it's good.

But, if all that works then the installation would proceed normally,
so presumably something looks different for you.
