I have a file win7.vhd that I've been using in a Boot to VHD scenario. Now I want to run that Windows 7 instance within Hyper-V Server alongside a few other VMs I have. I sysprepped win7.vhd and copied it over to the the Hyper-V Server and tried creating a new VM using that .vhd file. I get the "Boot failure. Reboot and Select proper Boot device or Insert Boot Media in selected Boot device" error. Any suggestions?

When you boot (physically) from a VHD, the boot loader and a few other files reside not within the VHD but on the hosting volume, thus the VHD is incomplete when it stands alone (virtually, within a VM.)

You can probably fix it up by booting the VM from the Windows 7 installation CD and telling it to repair the boot volume.

i'm not quite sure what you mean by "booting the VM from the Windows 7 installation CD" could you elaborate? –  qntmfred Oct 16 '10 at 1:38
    
I meant: Attach the Windows 7 DVD (or an ISO file that contains the same thing) to your VM. Configure the VM to boot from the CD. Press the "start" button on the VM. –  Jake Oshins Oct 17 '10 at 6:04

I was able to successfully boot my vhd in Hyper-V Server using the sequence of commands found at http://www.ravichaganti.com/blog/?p=317

  • Boot into a Windows 7 Installation disc. When the wizard begins, open a command prompt by pressing Shift+F10
  • Open Diskpart
  • Select vdisk file=D:\Win7.VHD
  • Attach Vdisk
  • select part 1
  • active
  • Assign letter=Z
  • exit
  • Now, at the command prompt, change to Z:\Windows\System32
  • Run, BCDboot.exe Z:\Windows /s Z:\
  • Run, BCDedit /store Z:\boot\BCD /set {bootmgr} device boot
  • Run, BCDedit /store Z:\boot\BCD /set {default} device boot
  • Run, BCDedit /store Z:\boot\BCD /set {default} osdevice boot
  • Change directory to C:\
  • open Diskpart again and run
  • Select vdisk file=D:\Win7.VHD
  • detach vDISK
  • Exit

It sounds like you set up your VM to boot from a VHD from within the VM. I was suggesting that you make the VHD itself the boot volume of the VM. Either way, you seem to have what you want. –  Jake Oshins Oct 16 '10 at 23:17
