What you're looking for is called "Dual Boot", and allows you to install/boot two or more OS's into one machine.

The only location that is *really* important, is the location of the Windows installation; while it is possible to install Windows in locations other than its default place (first OS on first drive) it is really asking for a headache. So, easy way: Have windows installed to the first HDD like usual, and then boot Ubuntu and use the built-in installer to install it to whatever drive/partition you want it in. The Ubuntu boot-loader should automatically detect the Windows OS on the other drive, and will add it to the boot menu that you get when you turn on the machine.

Please note: In the Linux world, there is no "C" or "D" or "G" drive. Each drive gets a letter, and each partition of a drive gets a number; typically hard-drives are labeled in order of their location on the bus. So as an example, the first hard drive, where your Windows is, might be labeled "sda", and the first partition, where Windows is, would be "sda1". A second hard drive would then be "sdb", a third would be "sdc". Partitions go in numerical order: sda1, sda2, sda3 etc..

Anyhow, read around a bit about "Dual Boot" or "dual booting Ubuntu Windows" and you will have near limitless reading material. Good luck, and welcome to LQ!

You have two (common) options for a dual boot. One is to use bios to select the first bootable active partition if your system is new enough.
You can leave xp untouched. Open bios and select the second drive as first boot choice and install linux. It should do fine but as with all this BACK UP first.
I tend to prefer this if I have odd installs like xp on odd raid card.

Second is to do what many people do as stated by GrapefruiTgirl. A dual boot using a single hard drive partition active wtih a boot loader either MS or Grub or another to select the OS.

There is a quite safe third choice too that you should consider. Install a Virtual Machine in the current XP. You can very safely run both OS's and can keep some room on the extra hard drive for xp's virtual space to help speed up the system a bit. It would run a bit slow on your system so that is way I left it as last choice.

to jefro

Please tell me more about using raid cards ( ie expansion cards) as I have had problems installing and upgrading distros when connected via an expansion card in lew of a second connection(ide) to the motherboard.
Sometimes the booter connects with the system, or not. Typically with several linux systems, and the option to boot all, it will only boot the first and I think that this to do with the physical set up but why does it install or boot.

All of modern installation will offer to you really easy to use graphical partitioning tool during the installation. You can do as you like just by reading the guidelines on a screen. I have linux jazz set, and all of them allow easily set any configuration for as long as you have enough space left on the drives. I remember I was struggling with it two years ago, it is not problem anymore. Fedora 13 is especially nice in this regard. My set came from Amazon, but you can get it elsewhere

What about WUBI!

Personally, I would download the latest distribution of Ubuntu: Lucid Lynx, burn it to a CD as an ISO. Go into your computer's Bios and make the CD ROM drive as first boot. With the ISO CD in the drive, reboot your computer. Look for the offering of installing Ubuntu via WUBI on the ISO disc. Look up WUBI and ISO on Google for more info..
Wubi will allow you to install Ubuntu on your XP's C drive as a file.Therefore, there is no altering of your current partitioning or XP setup. Simply use ubuntu as a file, after the initial choice of logging into either XP or Ubuntu when switching on your computer (dual-booting the easy way!).

C and G are not actually hard drives. They are partitions.

You probably should figure out what D, E and F are before doing anything to "G". I expect one of D, E or F is a CD or DVD drive. Do you know what the others are?

Linux does not name hard drive partitions (nor CD/DVD drives) the same way windows does.

Linux probably names your hard drives sda and sdb, then names the first partition of each sda1 and sdb1.

my question is how can I install Linux unbunto 8.0 in the G unit without uninstall windows xp in the c unit
There are many ways to set up a dual boot. The simplest to use and simplest to install (pretty much the default in the Ubuntu installer) is to let Linux take over the MBR of the first hard drive for the Grub bootloader. The Ubuntu installer will automatically create entries in Grub to allow chainload of Windows.

With Windows on the first drive and Linux on the second, that means the MBR on the first drive is set to load Grub from the second drive, then Grub is set to offer you a choice of chainloading Windows from the first drive or directly loading Linux from the second.

As I said before, that is easiest to use and easiest to install. It is not easiest to uninstall. If you wanted to remove Linux, you would need to first run the fixmbr program in Windows to get Windows to take back the MBR of the first drive. Other forms of dual boot are harder to install and in some forms also harder to use, but wouldn't need fixmbr if/when you remove Linux. I prefer the default choice, needing fixmbr. But I wanted to tell you that there are choices.
