installing Grub on a Harddisk image
Re:installing Grub on a Harddisk image
Version of GRUB?
Which Emulator? (Bochs?)
Exact procedure followed?
Error message?
Come on. Only precise questions get precise answers.

Re:installing Grub on a Harddisk image
FreeBSD 5.2-current
GRUB 0.95
bochs 2.1.1
on linux....
dd if=/dev/zero of=~/bochs/30M.disk bs=516096c count=61
losetup /dev/loop0 ~/bochs/30M.disk
fdisk /dev/loop0 #did this in interactive mode...
losetup -d /dev/loop0
losetup -o32256 /dev/loop0 ~/bochs/30M.disk
mke2fs -b1024 /dev/loop0 #blocks can't remember the number of blocks... easy enough to find tho...
detach the loopback again...
move the file to the bsd box.... used SCP for this... simple enough...
mdconfig -t vnode -f bochs/30M.disk
mount -t ext2fs /dev/md0s1 /mnt
grub-install --root-directory=/mnt /dev/md0
and then I get a nice little message saying that md0 is not a bios device...

Re:installing Grub on a Harddisk image
Try the technique outlined here:
http://www.uruk.org/orig-grub/install.html
Only difference would be that you'd create /boot/grub (And copy the stage2 files) when you have the partition hooked up on the loopback device.
Then load up the emulator of your choice from a grub floppy and install to the emulated harddrive.
Should work...I think...maybe ;D.

Re:installing Grub on a Harddisk image
fine for floppies... the problem is preserving the partition table tho... if you just do the dd you over write the partition table.... of course... hmm... if you don't copy the full 512 bytes.... that might work....
update :
nope no workie... least not dd to a file... kills the rest of the file... now... to a device... about to test that

Re:installing Grub on a Harddisk image
You could set up a floppy image file, dd' GRUB (stage1 and stage2) to it, and then boot Bochs from the floppy image. That brings you to a GRUB prompt, and you could install GRUB to the hard disk image file from inside the emulation...?

Re:installing Grub on a Harddisk image
That's what I was suggesting Solar.
There's no possibility of just being able to DD to the hard-drive image.
