Hello,
the idea sounds nice, but AFAIK this is not possible.
The GRUB shell (offline tool) can read and write image files
but not the online GRUB loader. And also if GRUB would be able
to do so, DOS itself cannot.
Think about it: You load the DOS boot sector from a image file,
ok, but this DOS loader (boot sector) tells to processor to
find the msdos.sys and io.sys (or whatever name those files
have, hidden on a drive). For this loading the INT13 is used,
and this BIOS call cannot access a image file !!!
It comparable to LINUX: Perhaps you can load a kernel, but then
there must be a support under Linux to mount the root file
system. If Linux does not support the way accessing the root
file system, Linux cannot continue to boot....
With friendly regards
