i have a multiboot set up with vista, ubuntu 8.04 and ubuntu 9.04 . everything was just fine : even edited the grub menu successfully to boot vista first. THEN i decided i did not want 8.04 and formatted the partion it was on and installed dreamlinux there. Thats when my problems started. After the dream linux installation, all i had was its bootloader and could not choose any other OS so i reinstalled 8.04 and got back to the set up i had before but now my computer will only boot to the recovery mode of 9.04 . I have edited grub and it shows that the changes i made are there but it continues to boot in the 9.04 recovery mode. I also have redundant copies of 9.04 in the list so i have no idea what i screwed up but if some one could help me get back to where i was when everything was blissfull in my world i will be so gratefull and promise not to tinker til i educate myself in linux a bit more. Here is what i have in the grub menu:

# WARNING: If you are using dmraid do not use 'savedefault' or your

# Set a timeout, in SEC seconds, before automatically booting the default entry

This menu you entered here is empty just example for update-grub script.
Now you have who knows how much /boot folders and kernels....
---
To keep things clean create /boot partition like 0.5 Gb make it bootable merge all /boot contents from all Linux installations to it and install grub to it.
----
This is kinda standard configuration, but Linux "user friendly" distros tend to avoid those "difficulties" with 4+ partitions. But when matters come to 3+ distros booting from same hdd this manual setup is almost must-have.

I am getting the impression (from all this reading) that I should have mulitple partitions. My question is if that is the "way its supposed to be" why did the Jaunty CD I just installed only have the two options?

I could keep windows (no). or I could "give Ubuntu the entire disk" and I got one 40g partition... do I need to change that as well?

Flugo, download and read the instructions for "Super Grub". You may be able to fix your problem this way.

SheaMan, There should have been a manual install option listed which would let you set up the partitions as you wanted.

Liolikas , thanks so much for replying but i am brand new to linux and i have no idea what you just said. I don't think that is just an example, i navigated to that page by using using this code " gksudo gedit /boot/grub/menu.lst" in terminal and then i edited it to have windows boot first - and it worked great til i installed dreamlinux on the partition that had 8.05 installed on it. now no matter what changes i make to the grub menu, it still does the same thing as i described earlier. I have no idea what all is being said in that grub menu page nor do i understand your suggestion to " keep things clean create /boot partition like 0.5 Gb make it bootable merge all /boot contents from all Linux installations to it and install grub to it. it almost seems like it would be easier to delete all partions but the one windows is on and start all over but i really don't want to do that. Help

it might be easier for you to install another boot manager like " GAG" .... http://gag.sourceforge.net/ ( you will need grub installed in the front of each partition to load linux , but it's great if you , like me are often installing different distro's)
