can't boot into Linux, and haven't run coLinux from Windows for a long time. forgot everything. this is how I think I fixed it; if I can now reboot into Debian and upload this, you'll know it worked.
I had to right-click cmd.exe and run as administrator (not sure this was necessary, but can't hurt). Then cd to \Program Files\coLinux and run colinux-daemon @\Users\jc\Documents\debian.conf. It fails to initiate properly, but gives me a root prompt. From there I:
mount /proc mount -t cofs cofs0 /media/sda3 dd if=/dev/sda4 bs=512 count=1 of=/media/sda3/debian.bin
