Yes, I realise that, having set up quite a number of 'em. But Linux
doesn't seem to mind the odd DOS partition here and there, whereas DOS throws
a wobbly (in the above example) when formatting Partition 2, if Partition 6
is non-DOS. Very weird, but it did it for me, it did it for Pigeon.

Yes, I agree, but all the rescue disks I've tried (tomsrtbt, RIP and Leka)
have fdisk on 'em.

Thanks! In fact, I'm now running GRUB on my main Linux drive, /hda, and I'm
intending to modify it to boot the DOS/Win drive which I'll put into the
system as /hdc. It should just need an addition to its kernel list (or so I
hope). But anyway I've saved the article.
Actually, I just took a look, and what was the first thing I saw but
a mention of FDISK /MBR to uninstall Grub - just what I was wanting to do on
this drive. How opportune! :)
