I have an interesting issue that I think was caused by hitting the "esc" button during bootup instead of the normal "F1." I was using powershadow and FDISR successfully for awhile now and just because this button was accidently hit during the boot process I've now lost powershadow quit function. It puts you in a never ending loop. I hope I haven't found another MBR issue since both programs sit in the MBR. Anyone here using both that could do a test for me and hit esc instead of the normal f1 during boot and see if you have the same thing happen to them? Erik and Pete don't answer this. I think I already know what your answers are. Problem solved. Needed to disable then re enable preboot screen.
