iso-scan is not responsible for the unmounting of /dev/sdX. I do not
know why I implied it was.

It would be good if you would say whether this works for your situation.

However, within the context of your chosen installation method, it is
sufficient to return to the third menu option (Scan hard drives for an
installer ISO). This will unmount /cdrom, then mount /hd-media and
/cdrom again. You can then continue from where you left off.

The same result can be obtained with

   umount /cdrom
   mount -tvfat /dev/sdX /hd-media
   mount /hd-media/<yourISO> /cdrom

from a console session.

It should be noted that the method you have used for booting from a USB
device should be used only if you have some special requirement which
cannot be met by the recommended technique in Section 4.3.1. In the vast
majority of cases setting up the device for booting from an isohybrid
ISO is reliable and will suit most users.
