It's difficult to say if this is a bug in grub, unless the bug is that grub hangs when re-installing the bootloader.
But, to see if it hangs again, you could try reinstalling grub after booting from a CD. If you're booting from the live CD, running sudo grub-install /dev/sda (assuming that is your one and only disk, which is generally the case on a MBP). Or if you are booting from the 'alternate' CD, there is a menu option to reinstall grub. If the one doesn't work, try the other. And report if either one of them hang, or give you any other errors. Also, if you could post your current partition layout, that might help someone debug this, e.g. sudo parted -l -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/759192 Title: grub failed to update on Natty -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
