Karl, Mark.
I have solved the problem.
Recapping, the XP drive is plugged and jumpered as the master and the
Ubuntu the slave.
If I have the master drive plugged in when installing Ubuntu, the
partitioner correctly recognises the slave as 'sdb'. However, if I have
the master unplugged, it calls the slave 'sda'. In my 'un-expert'
opinion, this is in conflict with what it should be.
So, I have installed Ubuntu with the master plugged in and it now works.
I expect, but am guessing here, that I could alternatively have
installed Ubuntu with the other drive unplugged and edited grub/menu.lst
to change sda to sdb.
There's just one thing which has happened, which I didn't want. Ubuntu
appears to have installed its grub onto the XP drive MBR. I want to find
out how to reinstall the XP MBR and change the Ubuntu one to the sdb drive.
Thank you all for your help. I appreciate it.
Cheers
Keith
