good idea but ...

this not what I need,I'm using bochs but I need to run the OS in real environment,so I'm asking is it possiple to use an image as a real drive and I found some thing like this in grub (using the command device) but it didn't work with me

also I'm sorry about the misspelling asly kont nayem ala nafsi

try QEMU instead of Bochs BTQ

try QEMU instead of Bochs BTQ. And it is possible to use an image to boot from, but it is not trivial.

the easiest way for you is to put that image file at the beginning of its own partition.

people that do your kind of stuff should be using LVM2/EVMS2 in any case to create virtual partitions etc.

btw, knoppix includes an option to boot off .ISO image on the harddrive. still need the cd to start the boot but the rest is off HD

if you create a suitable 'initrd' it is not difficult to put into it something that loads the 'loop' driver and pivots to a root mounted on a loop. that's what knoppix does as I mentioned

however, you need a '/boot' external to the filesystem image to do that.


-I used to be indecisive .. but now I'm not so sure

I think QEMU may be faster bu

I think QEMU may be faster but there is always problems in running QEMU (at least with me)

"the easiest way for you is to put that image file at the beginning of its own partition" how to do this?

'initrd' is also good idea,but unfortunately the .iso is not a Linux it is ReactOs (open sourced win NT clone)
