Comment 12 for bug 554079

I had the same issue as well 2 days ago. I was stuck at 47% . I couldn't boot into recovery mode either - kept getting something about needing to run fsck manually.

I had to reinstall since I didn't have my live USB with me and my CD drive doesn't work. The only USB drive I had at the time was 256MB and didn't have enough space to make a new USB. And the Ubuntu minimal install wasn't out for Lucid yet :(

Next morning I got my 8GB live USB drive and reinstalled. I'm dreading the next time this happens!
