First of all please install Ubuntu with legacy boot. And don't try tboot in EFI boot, tboot doesn't support EFI boot yet. If you install tboot1.7.0 with the deb package in the Ubuntu repo, the 20_linux_tboot scripts will be installed into /etc/grub.d/, and the boot.cfg should be updated with some tboot menuentries. If you want to enforce tboot policy, you need to change the installed 20_linux_tboot scripts to add list.data to tboot menuentry and regenerate the boot.cfg. or you can directly change boot.cfg for shortly usage. > > With Ubuntu 12.10 Server they now use a file called boot.cfg that was > generated by grub-mkconfig from scripts in /etc/grub.d.

Should have that done by the end of the day. Serial log is preferred, but the memory log dumped with txt-stat is also helpful which is almost identical to serial log. Please provide the boot.cfg & log for further analysis. Jimmy
