Exactly, that's why I pointed you to a wiki page that explains how to get the
installer logs.

1) Access to a terminal by any of the methods explained in that page
2) Use save_y2logs as explained in that page to save the logs (save_y2logs is
available in the installer system)
3) Save the logs to some place in which you can access them later like a USB
stick, a partition of your hard disk, some network location (yes, a network
resource is not an option in your case).
