Cleaning up the list of o/s in a dual boot

[Jean Hollis Weber]

Now that I have upgraded to Dapper, my dual-boot screen shows 
quite a long list of Ubuntus as well as WinXP. The Ubuntu choices 
are 2 each (regular and "safe mode") for Dapper, Breezy, and 
Hoary. I assume that the Breezy and Hoary choices are redundant 
now, and would like to get rid of them to make the list of 
choices shorter and cleaner. Can I edit this list and if so, how?

Cheers, Jean
