It appears that you are trying to create and use a partition image
instead of a whole disk image.  I *think* Qemu expects that a hard
disk image will contain a partition table at the beginning of the
disk image.  With a partition table the kernel command becomes;

 kernel=(hd0,0)/hello.exe

I have posted full instructions on creating a Qemu compatible disk
image with FAT partition and grub here:

resources/rtems/create_hdimage.txt

I use FreeDOS to partition the disk, but you could use the
mtools mpartition command.
