Comment 43 for bug 441941

Just the latest bit of info I can offer. I've got a Compaq 8710p that does this too. I tried uninstalling each of the HP ProtectTools one at a time to see if I could determine which on was causing the problem. Each time rebooting and fixing using a LiveCD along with the commands "sudo mount /dev/sda6 /mnt" and then "sudo grub-install --root-directory=/mnt/ /dev/sda". After removing all components and eventually the HP ProtectTools Security Manager itself, it turns out that didn't work because it was still booting and hanging on the "Grub loading." screen. Only after I uninstalled the HP Recovery Manager did it finally end up working as it should. Perhaps that's all that was needed in the first place.
