[Ham-Computers] Dual boot problem

[WØQFC]

I have been trying for over a week now to set up a dual boot system on the new HP 6318f.
 
The biggest problem is that when I add the second SATA HDD I can not boot to that drive unless I change the bios setting from AHCI to IDE; and when I do that, the original SATA drive will not boot because the bios is set to IDE.
 
I can however, use the second drive as a stand-alone drive (on IDE), with XP installed and boot to XP normally but then I can not use the original drive with Win7.  (Hope that made sense!)
 
Bottom line is HOW do I add the second drive and use it on AHCI  ????
 
I am starting to think that Win 7 is a piece of CRAP!
 
Any help will be greatly appreciated.
