Hi,
Go interactive with grub
ie type c to go into command mode during booting

During install I have been selecting Install No Boot Loader
and then rebooting to linux rescue and sorting out grub
at this stage.

I have a nearly finished the document but it has not been thoroughly
proof read, but it may be useful. I take no responsibility !!!!
Any feedback welcome !!!!

I'm not sure whether attachments are allowed but I've added it
to see. See below !!!!!!!!!!!!!!!!!

Cheers
John
