hi, I messed up at partioning (schrinking C and expanding D) it works but in the proces i moved C behind D and D became the first partion on disk ( but not set active),obviously thereafter can't boot so i put a backup from SP back again but because of changings in partion layout it does not work so i deleted the volumes within the recovery enviroment and eventually i recovered my :C then at boot there was no FDISR bootscreen instead booting straight into windows with a BSOD with a stopmessage Returnil RSS.SYS driver conflict, and cannot even boot into safemode so i recovered an image way back in time with NO Returnil on it but after boot same problems and strangely with the Returnil driverproblem back again.[how is this possible ? hmm maybe Returnil protecting something ?] but in short i can't boot not even into safemode so i was thinking to zero the disk and then recover with a SP image,my question is because i can't boot at all, how to zero the disk and then to put back the image ? Thanks.
