Hi Alex, A disk image of a bootable partition, given as an ordinary file, is generally not bootable. Though GRUB can be instructed to load (at least the first sectors of) such a file into memory and start it, it is almost certain, that the started image, erroneously assuming it still resides on a disk in its original position, tries to access the disk and load further parts of itself using false addresses. Boot loaders (like GRUB) use 'fire and forget' strategies: After having started the very first beginning of an OS, their task is fulfilled, and the boot loader code is not called again. On the contrary, emulators like bochs run an image in a sandbox and intercept all calls to a disk, redirecting the call to the proper parts of the image file. The emulator lives (and has to live) until the started image finally shuts down. The difference in task and technique is really colossal, so I personally do not expect GRUB featuring such extensions soon.
