I am very confused about what you're trying to accomplish, and even more confused about what you've done up to this point. There is no reason that you should need to get stuck at a grub rescue shell when transitioning from an msdos label to a GPT label if you run grub-install properly (meaning, passing the device whose boot sector your BIOS is going to load, and if needed a proper --boot-directory argument, no --modules argument should ever be necessary) after making any partitioning changes. Please re-run grub-install (without --modules) and note down the exact command you ran, as well as the output of "mount" when you ran grub-install, and post both. If after that grub-install command you're still not able to boot, please run boot info script http://bootinfoscript.sourceforge.net/ from a LiveCD/USB or other working GNU/Linux installation and post the RESULTS.txt that it produces. -- Jordan Uggla (Jordan_U on irc.freenode.net) _______________________________________________ Help-grub mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-grub
