Safeguard Enterprise Client V5.50 crash on virual Machine (HYPER-V)

Hello,

I am  using Windows 2008 R2 with Hyper-V enabled. 

I installed SGN server on Windows 2008 R2 and it worked fine.

Then I installed SGN 5.50 client with Volume encryption enabled on a GUEST WIN XP SP3  machine and it crashed after rebooting. . This is what I am getting after rebooting:

Sophos Safeguard is starting

Please Wait...

Invalid Slice

No/ Boot Loader

I am not sure if it is supported on Hyper-V but if you follow this link it is supported on VMware.

Any help will be appreciated.
