Re: How to troubleshoot when stuck at "GRUB loading."?

[Anders Ingemann]

p.s.: I cross-posted this to the debian-cloud mailinglist
(http://lists.debian.org/debian-cloud/2013/09/msg00022.html). I will
cross-post any parts/answers that may be helpful to solving the
problem (and for posterity's sake, if anyone has a similar problem and
finds this).
