Virtual Disk Issues in Vmware ESX


I have found that most of us have struggled a lot when it comes to converting physical System to Virtual (P2V), Due to the IDE disk which VMware is struggling to understand. Generally we see such issues with windows XP, windows 2000 and windows 2003(64-bit).
Most of my colleagues have complains about.....

  • Virtual machine fails to boot with a black screen after P2V conversion with just blinking underscore on the black screen.
  • Or with some errors like “disk error occurred, press ctrl+alt+del to restart” after P2V, the virtual machine fails to boot.
