How to convert the virtual achine from VMWare to Hyper-V

MS製品を担いでる会社なのに、なぜか検証環境をVMWare Player 6で作っていたメンバーから、技術検証用の仮想マシンを貰った。
うちのチームは仮想環境はHyper-V2.0で統一してるので、仮想マシンをコンバート。
一般的なvmdk to VHDコンバーターは、MBRのコンバートができないらしく、起動させるまで一苦労。
手順をおぼえがき。

  1. VMDKをVHDにコンバート。最終的にStarWind V2V Converterを使ったが、 VMDK2VHD、NHCなど、どれでも問題ないと思われる。
  2. TestDiskで、ブートセクタを再作成する。→参考Rebuilding NTFS boot sector using Testdisk
