Dual Boot Issue.
Hey all, I really hope someone can help me with this.
I own an HP Pavillion a6720y Desktop PC. It came stock with Windows Vista Home Premium 64 bit. Almost immediately, I sought to upgrade to Windows 7. The installation kept crashing, and after doing some research, I learned that the system bios required a change of the controller from AHCI to RAID. After doing this, Windows 7 installed flawlessly. Recently, I got the need to have a dual boot with Windows XP. The windows XP installation BSOD'd shortly after starting windows executive. Remembering the issue with Windows 7, I decided to test those waters again. I have 3 options for the controller, 1) IDE 2) RAID 3)AHCI. When I changed it back to AHCI, which is where it was with Windows Vista, it still BSOD'd. When I changed it to IDE, XP installed flawlessly.
The obvious problem I have now, the dual boot is set up. But I have to enter the bios every time I want to change the OS, as Windows 7 will not start up with it set to IDE, and XP will not start up with it set to RAID. Is there a software fix that can help me with this, or is it simply something I am stuck with? I have set up dual boots for lots of other people, and no other system has ever caused this. Any help would be greatly appreciated. Also if anymore info is needed, please leave a reply, and I will supply the information.
