With InCD installed PC boots to safe mode

I’m having problems with a new hard drive that boots to safe mode after I’ve installed InCD. I have to restore the drive to regain control of my PC.
I’ve tried four different versions of InCD but always get the same fault.
My PC is stable without InCD installed. I know from reading other posts that many users would say ‘ditch InCD’. but its always worked well for me until now.
Any suggestons for a solution would be appreciated.
I’m using Win98SE.
