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

Niltze, Anders-

Cannot reproduce your setup:

$ git clone https://github.com/andsens/build-debian-cloud

$ cd build-debian-cloud

$ ./build-debian-cloud manifests/virtualbox.manifest.json
This script creates a Debian Squeeze Image for
either Amazon Web Services or Google Compute Engine.

Valid subcommands are:
    ec2    Build an Amazon Machine Image
    gce    Build a Google Compute Engine Image

$ ./build-debian-cloud gce manifests/virtualbox.manifest.json
Unrecognized option: manifests/virtualbox.manifest.json
Type './build-debian-cloud --help' to see a list of possible options

Best Regards.

Hey guys

I posted to help-grub@gnu.org, asking for help to figure out why my
VirtualBox image is stuck at "GRUB loading.". I thought that it might
be more relevant over there, but maybe you guys have some ideas as

Hello everybody

I am developing the debian bootstrapper "build-debian-cloud"
(https://github.com/andsens/build-debian-cloud) and am having some
trouble getting grub to boot my debian installation.
Since I bootstrap from a host system (with chroot etc.) I had to use
some workarounds to get grub installed onto a loopback device

The setup consists of a vdi image partitioned with GPT into boot,
root, swap (in that order).
I am unable to get past the "GRUB loading." message when booting the
image in VirtualBox.

I have a hard time figuring out what is wrong with the setup,
especially because the scenario is a bit off the beaten path (mounting
vdi as an network block device, bootstrapping, using dmsetup to fake a
real hdd etc.). So the usual "just run BootRepair" or "reinstall grub"
won't really help to create a stable bootstrapping process.
I have run Ubuntus Boot Repair system to check if anything was wrong,
but I can't seem to find anything. The output is here:

The setup can be fully reproduced by cloning my repo and running
`./build-debian-cloud manifests/virtualbox.manifest.json` (only tested
on debian wheezy).
Simply create a new virtual machine in VBox, attach the resulting
image and boot it.

I would appreciate any help you can offer
