Hello, David
I will print out your e-mail and study it, and the referenced documents,
carefully -- putting aside the temptation to rush and skip things in my hurry
to get things working again.
As the attempt to get everything working without using grub rescue seems to be
stalled (see my e-mail <[email protected]> in
another sub-thread), trying to understand grub rescue seems like the best use
of my time at the moment.
One comment:

given us some detail to work with. We can see your incorrect 'prefix' (or
something like it, because I'm guessing that you retyped that because
'debain@' looks weird.
I agree that it looks weird (and that I had to retype it): it should have been
"debian@" [which also looks weird to me, but that's what it said].
Having gone through the procedure in the other sub-thread, and thereby
installing a new MBR, what I now see at the "grub rescue>" prompt is quite
different (I have to take a photo of the screen, upload it to this computer,
and type what it says into this e-mail; I think I have done that without any
mistakes) [recall from that sub-thread that when the RAID MBR was written
there were two drives in the machine: /dev/sda was the non-booting RAID disk,
and /dev/sdb was the non-RAID disk that had supplied the running OS]:
"ls" now returns:
(hd0) (hd0,msdos2) (hd0,msdos1) (hd1) (hd1,msdos5) (hd1,msdos1) (md/0) (fd0)
error: failure reading sector 0xb30 from 'fd0'.
I interpret that to mean, in order:
the entire RAID disk (/dev/sda)
the second partition on the RAID disk (/dev/sda2)
the first partition on the RAID disk (/dev/sda1)
the entire non-RAID disk (/dev/sdb)
the fifth partition on the non-RAID disk (/dev/sdb5)
the first partition on the non-RAID disk (/dev/sdb1)
the logical RAID disk
the floppy drive
and there was an error accessing the floppy, probably because there was
nothing in the drive.
"set" now returns ("8d86...0aed" is shorthand for a long UUID):
prefix='(mduuid/8d86...0aed)/boot/grub'
root = 'mduuid/8d86...0aed'
Right, that's where we are right now. Now to print out your e-mail and
everything else, and when I get a bit of time -- this afternoon, I hope --
I'll try get my head around grub rescue.
