Since this is a "last resort" solution, you might experiment with some alternatives. 1) The second CD-ROM, the live file system. Copy from it to your existing system what you need--especially the kernel, /bin, and so forth. Delete files on the existing system newer than the ones installed. This will preserve your /etc directory. Reboot. If it fails, go to last resort. 2) The installation CD-ROM. Mount the CD and invoke install.sh in each of the distribution subdirectories (like /bin etc.). I think the bin distro installs a new kernel and also will overwrite /etc (you can of course back of /etc to ~/etc to preserve it for easy reinstallation first). Especially important would be /etc/fstab and anything else in /etc that was customized as a consequence of the installation process. You probably don't have to reinstall a lot of the distros, e.g., docs, proflibs, info.
