Can we have a GRUB that chainloads ALL partitions?

[sling-shot]

I have more than 6 bootable partitions on my laptop and more than 4 on my desktop.
I keep 1 PCLinuxOS and 1 Windows partition constant on both computers, but I keep re-installing / changing the remaining partitions at will.
I have a separate partition of about 50 MB on both computers.

My question is :
Can I install only GRUB to this partition and use it to chainload all other partitions including my main PCLinuxOS install?
In this case nothing will affect the main GRUB in whichever way I play around with installations on partitions.
If something happens, I only need to edit 1 menu.lst file.

I have a similar setup but I wanted to try a different approach.

Yes you can do that.
You must install each installation's Grub at the boot sector of the partition of that installation.
Then add an entry for each one, similar to this:

Code: [Select]

title Linux name
root (hd0,0)
chainloader +1

Changing the number on (hd0,0) to reflect the number of each partition.

You can have as many chainloader boot entries as you like.

I have had over 20 such boot stanzas at one time ......  difficult to go through the list to find exactly what I wanted 

title Linux name
root (hdX,Z)
chainloader +1

Change the X to choose the HDD
Change the Z to choose the partition on that drive.

I used a slightly different approach eventually.

I had only the chainloader entries for each disk in the menu.lst for that disk.
That helped keep the entries down to a manageable number in each.

The only edit you should need to make to the main menu.lst is if you add another partition to the disk.

Be sure you install Grub to the boot sector of each partition that holds an OS.
