As a precaution, hoping to circumvent other difficulties, I have read relevant parts of the Grub Manual and successfully produced a boot floppy.
This leaves me with a command line awaiting instructions about selecting a system to boot - there are options giving available commands, and a help file - but I couldn't discover how to proceed.
I can't find anything relevant in the Manual.
As usual, I shall be most grateful for advice or reference to other sources of information.
