first of all ( thanks for replay )
kon boot work with me very good on XP
but on 7 i got nothing
and i get no error message
i made a menue list and put this into it :
title KonBo
map --mem /FD0-konboot-v1.1-2in1.img (fd0)
map --hook
chainloader (fd0)+1
map (hd1) (hd0)
map --hook
rootnoverify (fd0)
and extract the konboot iso file into usb , and here is a question is there diffrence between konboot versions.
