My software always installs itself into the last partition on a disk (even if it has to create the partition). The following worked for me. # Set root to windows partition (just in case) root (hd0,0) # Try to find ours (it could fail) find --set-root --ignore-floppies /my_loader # Chainloader (since both use it) chainloader +1 This works because if my install is corrupted or incomplete it will still boot windows, but otherwise it will boot my partition (which eventually will continue on to boot windows anyway).
