Unable to boot bt5 x64 on vmware

Hi all,
I have windows 64 bit installed on my system. Recently I tried to install backtrack5 on VMware. After its installation I tried to boot my system but when I try to boot I get an error on my screen.
The screenshot of the error is as follows:
I am using an Asus machine with a CPU Intel d220 Celeron. I have upgraded my ram to 3 GB.
Can anyone please explain how to remove this error.
I am really looking forward to hear from you all.
Please help me out. Thanks in advance.
Kindest regards.
Jacob
