      @ram: If you haven't these options, Windows 8 cannot be installed on your system.

    I found the VT and DEP features in my bios settings and turned them on. I went further to change BOOT SPEED from normal to fast, restarted the laptop and the securable came up with the 3 YES. The unfortunate thing now is that my system no longer take me to the bios setting with the default F2 KEY. In short I cant access my bios setting since then. help me 'cos I cant choose from boot options

    It seems that I have worked out this problem. After changing the version option in VM settings from Windows Server 2003 Enterprise Edition to Windows Server 2003 x64 Edition, it can boot successfully from PCUnlocker without any problem. Thank you!

    I have run the SecurAble application on the physical machine, it displays two "YES". While running this program on my Windows Server 2003 virtual machine, the Hardware D.E.P is YES but the Hardware Visualization is shown as "Locked ON".

    I have purchased a Dell laptop that came with Windows 8 pre-installed. I try to boot a Windows 2003 virtual machine (VMware) from PCUnlocker (a bootable ISO image based on Windows 8 PE), and always get the "0x0000005D" error as what you described above.

    I have gone through all the settings in the BIOS of both physical machine and virtual machine, I can't find the Data Execution Prevention feature (Execute Disable or No Execute Memory Protection) at all. I can find the VT option which is enabled by default.

    So I am still unable to work out my problem. Please help!

      Hello Jullia,
      Maybe you processor doesn't support Data Execution Prevention and Virtualization Technology (VT) features.
      See processor specs to find it.
