After migration finished windows cant boot and Blue Screen of Death with error 0x0000007B this happens since the physical server had ISCSI drives, you need to tell windows to start with IDE first, to do that you need to edit the registry on the VM :
boot with windows repair or Hirans cd, or just mount the Virtual Disk on the host itself -> load the registry hive -> Expand HKEY_LOCAL_MACHINE/SYSTEM/ControlSet001/Services/intelide
Change the data for value “Start” from “3” to “0”.
– Also repeat the same process for the keys listed below in: HKEY_LOCAL_MACHINE/System/CurrentControlSet001/Services/ and edit the “Start” parameter to the corresponding value from the list:
Aliide = 3
Amdide =3
Atapi = 0
Cmdide = 3
iaStorV = 3
intelide = 0
msahci = 3
pciide = 3
viaide = 3
exit registry and reboot
This helps !!! the first boot is extremely slow.
