Hi. I use GRUB to load another bootloader(chain-load). Everything is OK, but I have a problem in making rescue disk : when I boot the system with grub-rescue's created ISO image file, it can not load my bootloader(2nd bootloader) and it hangs. As you may know, 'grub-rescue' creates an ISO image Rescue file that uses 'no emulation' mode. I need to make a grub rescue image that uses 'floppy emulation' or 'harddisk emulation' mode to chainload my bootloader properly. Can someone help me how to do that?
