Sorry to hear that. By all means do ask the list!

That is what I am suggesting.

Ubuntu defaults to GRUB in /dev/sda as I understand it. However, it
will remember where you specify it to go and use that from that point
on.

I have a multiboot PC with all OSes having their own bootloaders in
the superblocks of their root filesystems, and only 1 "master" distro
in the MBR. As it happens, for me, that is Ubuntu.

If it's in *that installation's own root filesystem* then that is
where it should stay.
