Blue screen after converting to SCSI controller type from IDE

Hi,

Any idea how to convert IDE controller to SCSI controller in Windows xp (32 Bit) OS?

This VM has just one primary disk.

I followed this KB article, But it leads to Blue screen error

Even I tried with lsilogic, but nothing works.

Any idea, how to resove the issue or How to convert IDE controller type to SCSI controller type without Blue screen error?
