So, in an attempt to do something quite challenging, I have began the process of trying to get Ubuntu 11.10 running on my USB external HD. I was able to successfully install Ubuntu on the external. Then I encountered the common Mactel bug (root error). I sycned the partition tables using rEFIt. Then I encountered one of two things- either the perpetual Linux penguin logo, or a "no operating system" in white text on a black screen error. I tried booting from the Live Ubuntu CD, going into terminal and recovering Grub, but I finally ran into an error I can't figure out.
$ sudo mount /dev/sdc1 /mntI'm smart enough to understand that Grub thinks this is a bad idea, my question is, why? And more importantly, what is a blocklist?
$ sudo grub-install --root-directory=/mnt /dev/sdc1
grub-setup: warn: Attempting to install GRUB to a partitionless disk or to a partition. This is a BAD idea..
grub-setup: warn: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and their use is discouraged...
grub-setup: error: will not proceed with blocklists.
I don't have enough free disk space to run Ubuntu on my Mac, hence the attempt to get it running on an external. I am aware this is generally considered undesirable, but it seems like the best option for me as I am wholly interested in running Ubuntu using virtualbox. Unless anyone can attest to successfully using a USB drive to boot Ubuntu on their Mactel. Any help is appreciated, thanks in advance!
