Re: MBR Confusion? (was: Building i386 Disk on AMD64 -- chroot Fails: Exec format error)

I've attached an external hard drive to my etch AMD64 box, booted my
AMD64 box into the debian installer, and installed a fresh i386 etch
onto the external drive.

Now I can't boot my box without the external drive attached, because
grub complains with "error 21." I'm thinking that when the debian
installer made the external drive bootable with my new i386 etch some
stuff happened with the master boot record or something. Also, when I
put the external drive into my Pentium III box, nothing happens.
Apparently the right MBR stiff is not on there.

Anyway, I'm in a bit deep at this point. Hopefully there is some simple
way to prepare the external drive on my AMD64 box to be the internal,
bootable drive of my Pentium III, and to tell grub on my AMD64 box that
it doesn't need the external drive attached in order to boot.

Go ahead and laugh. Just give me some good advice when you're done.
