Restores or exports cannot be performed directly to legacy BIOS servers or Hyper-V Generation 1 server as the automatic restore mapping will be still create the disk as GPT partitioning.
Also specifically, 2008 R2 EFI original servers also cannot be exported or BMR to Hyper-V as 2008 R2 is not supported in Hyper-V Generation 2 and EFI is not supported in Hyper-V Generation 1.
A conversion to MBR partitioning is required for the BMR to be successful in this case.
First part, creating the MBR partitioning manually before the restore
Second part，performing RapidRecovery BMR on the RapidRecovery core.
If the server is not booting up correctly with black screen/MBR issues, please continue to the third part to perform boot repair using the OS CD/DVD.
Third part, OS CD/DVD Repair (Please use the same OS CD/DVD as the original OS to perform the repair)
