Well, some observations and see if gregrocker agrees.

You installed Win 7 on the smaller drive, but the larger drive was primary at the time, so Win 7 installed its boot files on the System Reserved Partition on the larger drive.

The reason you can't install XP on the larger drive is the System Reserve Partition. This issue is still in doubt with some folks but I believe it hinders XP from seeing itself. There is a way to install XP in the current configuration, which entails making the XP partition active now and change it back later, if you want to keep your current configuration.

If I were you I would do the following. This will basically go around the System Reserve Partition and you will not have the Repair option during boot as you do now.

------------------------------------------

Boot to Win 7. Open an administrative command prompt window and type:
bcdboot C:\Windows /s C: <-- spaces between t and C:, s and /s, /s and C:

then hit enter and you should see a confirmation.
Then close the Command window.

This will put the boot files on the Win 7 partition.

Then open Disk Management (diskmgmt.msc) to make the Win 7 partition active.

After that, use the bios to change the drive order of the drives, or unplug the larger drive and you should be able to boot into Win 7. After you boot once, you can re-attach the larger drive.

Now you can get rid of the System Reserved partition if you like. If you want to keep it, we may have to do something else.

If for some reason the above does not work, just reset the drives so the larger one is primary in the bios and you will be back where you started.

There are other ways to do it, so wait for some more feedback.

I agree that the 100mb System Reserve partition is a hindrance on the separate HD from Win7 and may need to be removed, but what is likely blocking XP install is that you're trying to install it to a logical partition.

That partitioning needs to be deleted, then use the XP CD to create New partition formatted NTFS primary before installing XP.

Use Method Two here to set up the Dual Boot: Dual Boot Installation with Windows 7 and XP

To get rid of 100mb Sys Reserved, I'd use free Partition Wizard bootable CD, rightclick 100mb to delete, then rightclick Win7 to Modify>Set Active, apply all steps.

Make sure Win7 HD is set to boot first in BIOS, then boot into DVD Repair console to run Startup Repair 3 separate times with reboots to write MBR to Win7.

Please post back a screenshot of your full Disk managment drive map, using SNipping Tool in Start Menu, attach file with paper clip in reply box.

This can likely be sorted out by downloading/installing EasyBCD 2.0 beta - you need to do a quick registration to use beta.

If XP appears in the Easy listings, first remove it in Add/Remove tab, then add it back by name, accepting prompt to install boot files when you click Add OS. Then highlight XP listing above and Save.

Yes, run it from Win 7. It will put the files you need in the Win 7 directory and set up the boot for you.

How are you attempting to boot to XP?

easy bcd 2 froze after i hit save, but after i restarted it, it showed that the windows xp entry was there, however selecting windows xp from the boot menu still says ndltr is missing. i also noticed that when adding the windows xp entry it wouldn't let me choose the drive letter and was stuck on C:, even tho windows xp was installed on the E partition...

I don't really remember having to hit save, just the Add entry button. You are using the 2.0 version, right?

You might want to remove the entry again and just add. The drive letter will be greyed out because it knows where the boot files are. When it asks to transfer files, let it do so.

Basically the boot files (ntldr, ntdetect, boot.ini) are placed in the boot partition, which is C: designated by the System notation.
