Hi, an hour ago I came back to my office and saw on my Laptop’s screen in big letters: “No Boot Device”. That means that during last night’s Qubes Backup the system crashed, but wouldn’t know why. Before I started the backup I did shutdown all Qubes except of sys-usb and dom0 of course. I use sys-usb to mount the external USB disk on which I do the backups. That never happened before in the last 3 months.
I think for some reason grub got corrupted. So, I started Tails and the partitions are all there. So what I think I have to do is to re-install grub. I found this document http://qubes-os.org/doc/mount-from-other-os/ which tells me how to mount the partition so that I could chroot into it. But since I’m not so accustomed with Xen I don’t know how to re-install grub.
Any help would be highly appreciated.
System in question is described in the below post, which is the HCL + support files I contributed a couple of days ago:
