Grub-mkconfig generated a menu entry without an initrd line, despite

this follow up to step
two, then in the chroot run "apt-get install --reinstall

I want to thank Jordan, with whom I had the pleasure of chatting via the #grub IRC channel at Freenode Sunday evening, immensely for his help in solving this problem! Though I think the loss of the initrd file had something to do with the filling up of the /boot partition during a software installtion from within Synaptic, which is the reason I decided to enlarge that partition, by following the procedure outlined above, I was in fact able to restore my machine to a bootable state.

This whole experience taught me both a lot more about GRUB than I really wanted to know just at this point and that the subject is a lot more complex (or at least it seems so) than I had ever imagined. Though surely comprehensive, I think the way the GRUB manual is organized makes it hard to use as a learning resource - it reads more like a reference manual than a tutorial - which may be alright, if there are some good up-to-date HOWTOs out there someplace.

I just know that without Jordan's help, I likely never would have been able to find an fix this problem, since I hadn't known anything about initrds and UUIDs, and only enough about utilitiesss like fdisk, for that matter, to be able to get by before going through what I did.

Thanks again ever so much to Jordan, both for his suggestions and for the time he gave so generously last night. I am deeply in his debt!
