I'm glad you got it working! :) Try run 'qubes-hcl-report' in dom0, and check if HVM, I/O MMU, HAP/SLAT, TPM, and Remapping, is working properly in your Qubes setup. The top one, HVM, as far as I know is the most important one. The lowest, remapping, should with my limited knowledge as far as I can tell, be the least important of the 5. All of them are relevant for security, and to some extent, proper working features. If I'm not mistaken, I haven't ventured into these waters before, and someone might correct me here. But I believe if a Qubes (or Linux in general) uses the same partition table as UEFI/EFI (GPT), over the old out-dated MBR), then it might be possible to switch between UEFI/EFI and Legacy/BIOS without re-installing a system if retaining the modern GTR partition table. But it can be tricky if something goes wrong, especially if you have precious data you don't want to loose. Also UEFI/EFI is heavily reliant on not having a buggy motherboard firmware, which many unfortunately have. I also recall having issues not being able to restore an EFI path for Qubes 4, which used to always work on the same machine on Qubes 3.2. I'm not sure if this got fixed, it was some months back and Qubes 4 has rapidly been updated on many ways since then. But this issue is likely to be Qubes related, or at least partly Qubes related. So it's not always the hardware that is causing it, although the hardware in this case might be part-reason still. Remember to take frequent AppVM backups. If you're learning with the trial and error method like I do, many things can end up going wrong. For example, burned my fingers more than a few times my self there before I got into proper backup habits. Never take that risk, it will eventually go wrong :') -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
