Dual Boot XP x86 and 7 x64

I have several tutorials saved in my favorites that go through configuring the boot loader.

The main thing I'm wondering about is the fact that I had to change the "Configure SATA as" option to IDE in BIOS to load/install XP. I have to then change it back to AHCI to load/install 7.

On system startup it gives me the option to load the Earlier Verison of Windows or Windows 7.

If I load XP with it set to AHCI it will give me the blue screen and restart.
If I load 7 with it set to IDE it will give me the blue screen and restart.

I installed XP Pro x86 first.

I haven't changed any settings with EasyBCD 1.7.2 (I'm using this link mainly How to dual boot Windows XP and Windows 7 (XP installed first) )

Do I have to change anything or do anything different because I had to change the Configure Sata As option? Or can I go ahead and configure the bootloader like in the tutorials and everything will work and boot fine without having to go into BIOS and changing that option?

Thanks in advance

I found drivers that are supposed to allow XP to load while using AHCI when slipstreamed into the disk. Do I have to uninstall windows 7 AND XP, and then install XP first and windows 7 second?? Or is it possible to just reinstall XP and still be able to dual boot?

actually you are able to do the install (meaning the xp install) as long as you have a working windows 7 dvd you can boot from it and click repair your computer....
follow the prompts....

if not then click on startup repair...

it should load and write 7's bootloader....
from there you can bcdedit and write xp in there...
