I assume you meant "fdisk -u" which let you change partitions individually.

Well, I did this and fdisk changed the last line
from        end: cylinder 1023, head 255, sector 63
to          end: cylinder 1023, head 28, sector 21
but booting still dies with "Invalid partition table".

I then wrote a selectable mbr (with the -B option for fdisk)
although I only have one choice to boot, and it worked!!!!!!
Trying to get rid of the selectable mbr (fdisk -i) resulted
again in "Invalid boot partition".
So I did the fdisk -B again and set the timeout to 0 and it
all worked again.
I guess I have to live with a selectable mbr.

Hans.
