wanting to install multiple o.s.

[rhythmiccycle]

i have an old pc with a 15 gig hd.

right now i have a 5 gig partition, with puppy linux running on it.

the other 10 gigs are unpartitioned space.

ideally, I would like to have 3 o.s. on the p.c.

*puppy linux, because its an old p.c. and puppy runs well.
*ubuntu linux, because I know the most about ubuntu linux(vs other distro's).
*windows xp (black), because there are some programs that are only available on windows.

I know how to partition, and i know how to install an os on to a partition.

but i don't know how to set up the start up, so it will ask what o.s. do i want to run.

i know that puppy linux is using GRUB to boot. but i really don't know much about GRUB, besides that fact that it has to do with booting, and i think i need to configure it somehow, to run a multi o.s. system

can anyone tell me, at least, what to do (during and/or after) installing ubuntu on to another partition, to make it so I'll be asked what o.s. to boot with when i start up.

(if someone knows how to include windows xp black too, that would also be nice.)

You don't have to configure it, at least not the Ubuntu version. It should show the menu screen with available OSs to choose from. Here is a good guide for GRUB. http://members.iinet.net.au/~herman546/p15.html

I have it working now. thanks

The problem i had before was that I insatled ubuntu first then tried to add puppy linux.

but this time i installed puppy first, and then installed ubuntu second, and during the ubuntu installation there was an option to install side by side.
