after reading the posts from dencorso and jaclaz i tried this: i cut all the files (including setupldr.bin) from ROOT\minint\i386 nd put them directly in ROOT\minint so that minint folder now contains folders as :programs ,documents,fonts,system32... and files as:setupldr,bootsect,win51ip,txtsetup... and booted grub but unluckily i still get that message so i wish i didnt miss sth this time
