How to boot grub in /dev/sda2 from removeable disk?

[Greg Smith <rys@xxxxxxxxxxxxxxxxxxxx>]

Work gave me an IBM Thinkpad T43 with Windows XP installed.

I am attempting to install FC5.  For various reasons (including it not 
being so obvious that I have linux installed) I do *not* want to install 
grub in the MBR.

The partitions are /dev/sda1 (XP) and /dev/sda2 (FC5).  I know how to 
install grub on /dev/sda2 (by checking `configure advanced boot loader 
options').  The doc says ` Your computer must have GRUB or another boot 
loader installed in order to start, unless you create a separate startup 
disk to boot from**'.

How do I create a separate startup disk (CD)?

Thanks,
Greg Smith
