/dev/sda5 is my root partition;
/dev/sda2 is my boot partition,
but I had mounted this as /mnt/sda5/boot .

The /dev directory was empty, IIRC .
I'm sure I should have carried out something like the
        mount --bind /dev /tmp/local/dev
before running chroot, as suggested.

I've always found it difficult to tell Windows what size partition
I want to give it.
It seems to want to decide for itself.
[I hasten to add that I am not a Windows expert;
I never (or very rarely) use it,
but my grand-daughter uses Windows to play Sims-2.]

In this case, Windows seemed perfectly happy
with the 40GB NTFS partition created by Linux fdisk.
