      I have restored a Windows Server 2008 R2 server that was backed up from a physical machine to a Hyper-V VM.
      I could attempt a P2V, but I'm testing out my backup solution for recovery purposes as well as trying to convert this machine to a VM.

      The VM won't boot. I get the following error:

       Windows failed to start.  A recent hardware or software change might be the cause.
      

      After accepting "Launch startup Repair (Recommended)" I get:

       Status: 0xc000000e
       Info: The boot selection failed because a required device is inaccessible.
      

      Now I'm assuming that the boot device it can't find is the SCSI controller and drives it was booting to previously. As some of you know, you can't boot a Gen1 Hyper-V VM from SCSI, so you have to create at least the boot partition on IDE.

      I'm trying to discover how to use BCDEdit to change the boot properties to allow the system to find the new location of the boot drive, and hopefully boot.

      This is a pretty interesting read, although not directly helpful to my current situation. https://blogs.msdn.microsoft.com/virtual_pc_guy/2009/12/01/why-hyper-v-cannot-boot-off-of-scsi-disks-and-why-you-should-not-care/

      Any thoughts?

        From what I can tell, the system should just boot - rarely do I see anyone mentioning any problem, and where I do see a problem mentioned, I don't see solutions.

          Why did you make it a Gen1 VM in the first place?

          Nuke it and make it Gen 2 like it should be. Just turn off secure boot in the settings before you power on.

            Yeah I was wondering that.

            When I restored my disks, I restored them into IDE based disks... do you think this matters?

              I'm not very familiar with Hyper-V but if you need SCSI drivers to load the VM it appears you'd have to use a Gen 2 Hyper-V VM.

              here's how to use BCDEdit.

                Just start over. Don't try to hack something together. You should always work from a clean setup.

                  If you were under a DR situation, that would be different. You are in setup and test phase though.

                  So setup and test like you will for production. From a clean restore into the correct VM setup.

                    Thanks - I was under the impression that I need to use a Gen1 for something like 2008 R2... but that was my mistake... trying again - will restore the whole thing again.

                      OK no go... the system won't even try to boot off my vendor supplied recover ISO. When booting from Win2K8R2 iso, it hangs at the Starting Windows screen.

                        So Gen2 is out because 2008 R2 does not work in Gen2, which sucks, as my (obviously flawed) memory though 2008 R2 worked in Gen 2.

                        So it is back to Gen 1 for you.

                          Currently restoring just the 😄 drive in an attempt to just get the system booting.

                          If that works, then I'll restore the other partitions later.

                            @Dashrender Otherwise you may have to get third party software involve. Like VeeAM.

                              Or you could go P2V right now and update your DR. I am currently in progress of converting all of our servers into VMs.

                                Eventually I will end up where you are suggesting - though I currently use Dell's Appassure Replay, not Veeam.
