What I would do is put a live system on a USB flash drive (System Rescue CD is what I usually use) and mount the unbootable hard drive from within the live system. At that point you could wget a kernel deb from http://ftp.uk.debian.org onto your old mounted hard drive. chroot into your drive's mount point, dpkg -i linux-image-*, and you're done; your system should now be bootable. -- http://pobega.wordpress.com http://identica/pobega
