I recently did two installs of LMDE: one a dual boot with XP on a HP tower. Ran update immediately after, everything worked fine. Two, a clean install by itself to a Dell E6500 Latitude laptop. Install ran fine, can reboot. However, after running update several times now, laptop will not boot. Runs bios and then loops back to beginning running bios. Any ideas where to start. Maybe not updating grub?
