I'm trying to boot differents physical disk in gcloud. So the complete process is:
I dd the physical disk in linux (with a bs of 1G). Later i compressed in format tar.gz (with format=oldgnu, like gcloud want).
I uploaded that file in a google cloud bucket and later with gcloud compute, i converted that image.tar.gz in a gcloud image to boot a vm instance.
The problem is when i'm trying to boot that instance this error appears:
Booting from Hard Disk 0... Boot failed: not a bootable disk
I have tried to make a external disk with that image. I converted that image in a disk, and all my files are in there. All the partitions and boot partitions in there are in good state.
I read the documentation in gcloud for how to make the correct image, and how gcloud computes images. The docu about how windows boot in the vm is... unclear.
There is a exceptional way to boot windows in gcloud?
