[mythtv-users] appletv coexist with myth -- oops

[jansenj]

Well, my goal was to have mythbuntu and appletv software coexisting on
separate partitions on the appletv, then booting one or the other
depending on having a usb drive plugged in or not.

However, I must have made a mistake when installing mythbuntu.  I
resized the Media partition to make room for an sda5 and sda6 for
linux and swap.  Then when I went and installed mythbuntu I think I
should have gone into the advanced options and deselected the
installation of grub, but I didn't...and now I have a appletv that
won't boot...either partition.  It tries to boot the linux partition,
but is unsuccessful.  I'm thinking the install overwrote the MBR with
its own to point to sda5, but I don't want this, I want the harddrive
mbr to boot the appletv software/apple recovery partition, then have
the usb drive point over to the linux install.

Can anyone help me fix this?  I'm guessing I would need the original
MBR, would getting a dd copy of it from someone else work?  What would
that command look like and would anyone be willing to email me that
binary?

This looks promising, but not sure what to make of it, it sounds like
it would be for a pure linux install, not a coexisting install.

There is also some references to mbr_fast-1.0.bin out there, but not
sure if I could use this to fix the original mbr to boot the appletv
software.

Any help would be much appreciated, Thank You,
Justin
