what I meant was the people who wrote the scripts that generate
/boot/grub/menu.lst

ok, in future I wont redact the UUIDs

yes, but I prefer it to later versions, and it has everything that I need!

later versions are becoming more like Windows,


There is still a problem, I made the change, see below for the 
modified /boot/grub/menu.lst

By the way can I attach files on this list, or do they have to be 
included in the text?

what happens now, is that the new boot option appears, but when
I boot from it, I get the following error:

Error 12: Invalid device requested
press any key to continue...

which then returns back to the boot options.


I think the problem is that I have installed Windows XP to 
a logical partition, and grub probably only recognizes
OS's in the 3 or 4 top level partitions.

But Windows XP installation accepted a logical volume for the
installation, and it booted fine from this.

the reason I installed XP from a logical partition, is
that would allow me to have 3 Ubuntus and several XP's installed
from one drive. Ubuntu I think can only be installed
from a top level partition.

as there are a maximum of 4 top level partitions, and
a swap partition is necessary for Linux, if you 
only use top level partitions you can only have at most
3 OS's. 

But by using logical volumes for Windows, I could have
3 Ubuntus, eg 32 bit, 64 bit, and a scratch installation
in case I lose the boot options,


volume 1: Ubuntu 32
volume 2: Ubuntu 64
volume 3: Ubuntu 32 scratch version to retrieve boot options
volume 4: extended partition:
   volume 5: Ubuntu swap partition
   volume 6: Windows
   volume 7: Windows
   volume 8: Windows
   ....

I probably have to reinstall everything from scratch 
with the OS's all to top level partitions, right now
I have lost the solid state logical drive XP installation


the new /boot/grub/menu.lst is:
