Windows 7: Don't know how I messed up this XP/7 dualboot but...

I have 2 hard drives inside my computer. A 150 GB Raptor and a 320 GB Seagate. Both are SATA2 and they're both functioning properly. Knowing of the issues of trying to set up an XP/7 dualboot when 7 was installed first, I wiped both drives after backing up all my stuff, and installed XP on the Seagate. That went fine. Then I installed 7 on the Raptor. That went fine as well, but now when I reboot, Windows just goes right to 7. There's no Windows Boot Manager screen asking me what I want to boot into, so I installed EasyBCD 2.0, and XP's not there, it just says "Windows 7". Does anyone know what happened and what may have gone wrong? Cuz I'm at a loss.

Remove the Raptor, and see whether XP boots well or not
And I hope, you used EsayBCD properly. Click on add/ remove entry button, then add an entry for windows, click on the arrow, select windows nt/2k, xp/2k3, and finally add entry .

Now reboot to see if it is included in your mbr .

Since you have separate HD's you can boot via the BIOS boot order or one-time BIOS Boot Menu key which keeps the HD's independent instead of interlocking them as a Windows-managed Dual Boot does.

Since Windows 7 is booting now as first HD set to boot in BIOS boot order, tap the key given for Boot Menu of first boot screen or look it up in your mobo Manual. Select XP HD to see if it will still boot, as it should.

If you don't like booting in this way, Add XP as shown in Arc's screenshot above, accept offered boot files, let autocomplete, Save, restart.
