Comment 55 for bug 134660

Ok here are the guidelines and they do not suggest anything to do with booting or not booting, it is a bug that impacts a large portion of ubuntu users.

"Launchpad uses the following guidelines for assigning importance: Untriaged: the bug report has not be triaged yet. This is the default importance for new bugs. Wishlist: a request to add a new feature to one of the programs in Ubuntu. Use this for bugs which aren't really bugs but ideas for new features which do not yet exist. Low: bugs that affect functionality, but to a lesser extent than most bugs Medium: a functionality bug of the standard variety. Most bugs are of "Medium" severity. High: a bug that has a severe impact on a small portion of Ubuntu users (estimated) or has a moderate impact on a large portion of Ubuntu users (estimated) Critical: a bug which has a severe impact on a large portion of Ubuntu users."
