Grub 2 Made Easy
Most people in our freenode channel #puppylinux think that Grub 2 is confusing, and it can be. I tried for some time then gave up and continued booting from cd.
The information below was done using linux mint 10 and is a general guide. Most steps will be similar for other linux.
The first thing about grub 2 is that it can detect and auto generate menus for all os it detects. this can be good, it does have some drawbacks. For some os and os configurations it may use a generic name. My vista os was detected as "windows recovery environment". And it will not detect a puppy frugal install.
First you need to set up your puppy frugal install. Don't forget to save the extra files to make it boot faster when prompted to.
(As mint is built on ubuntu base here is a tutoral on grub 2 for ubuntu. Click Here)
You will probably want to turn on the OS-Prober feature so you don't have a messy confusing grub. I have found this easier. (when you stop OS-Prober it is ok to change or remove unwanted auto detected entries from grub.cfg under # BEGIN /etc/grub.d/10_linux # Remember to leave your os that the grub 2 is on).
In ubuntu baised os go to the file /etc/default/grub.
set GRUB_DISABLE_OS_PROBER=true (Enables/disables the os-prober check of other partitions for operating systems, including Windows, Linux, OSX and Hurd).
Now you need to go to /etc/grub.d/ (this is where you manually edit all your grub entries each filel edits a different part of /boot/grub/grub.cfg).
open 40_custom you will see this
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries. Simply type the
# menu entries you want to add after this comment. Be careful not to change
# the 'exec tail' line above.
here are my custom entries. (note that the main entry for Mint 10 I left in grub.cfg this is needed incase ou update the os changes).

Notice any entries beginning with # are ignored. its useful for infomation about each section or unused entries. to boot my other os i set up a link to there own grub menus for Mint 9 and Mint Debian. my puppy entries for quirky are booting frugal install on hdd and are there for an example you will have to tweak them for your own particular needs.
here are some other posts in forums that may be of interest.
