how to triple boot ubuntu with xp and 7?

I have installed 'WIN XP' 1st on HD1, then installed 'WIN 7' on HD2.. Now i want to install ubuntu 11.04 on HD3, means fresh install (not windows alongside). I want to know whether there will be any BOOT problem for XP and 7? Will it show all 3 os?

Please help.

Depends on how you installed windows. Windows can only boot from one primary partition, so standard installs literally move all boot files from the second install to the first. With two drives you can force the install to only be on that drive, but that is not the standard install.

To get each MS to have its own boot loader make a second primary partition and set its boot flag on, then install the 2nd product in it. Multibooters, Pictures here worth 1000+ words
A user who installed two windows & it worked to boot from grub directly
Another user who disconnected and used a second drive

You have to use manual install (Something else in Natty) to get where to install grub2's boot loader. You will want to install grub's boot loader to the Ubuntu drive probably sdc.
Then in BIOS boot using sdc.

Thanks everyone to reply.

Which installer should I use?

Ubuntu-11.04-desktop-i386.iso or Ubuntu-11.04-desktop-amd64? I have a 32-bit intel pc.

Which one is called natty narwhal?

thank you.

If your computer is so old to only have a 32bit processor you may not want the full Ubuntu. Almost all new Intel chips are 64bit and follow the AMD standard which just was backwards compatibility with 32bit Intel code.

Natty is 11.04.
