UEFI: AHCI to IDE problems

post #1 of 2

Thread Starter 
Hi everyone,
I am switching from AHCI to IDE temporarily in UEFI order to flash newer firmware onto my dvd-burner and it won't pick up my boot drive. So when I press F12 to find the correct drive to boot into I get a BSOD followed by a reboot. Is there a simple enough setting in UEFI to resolve this?
I will be running in AHCI mode again after the firmware flash is complete so I just need to have IDE enabled for the time being.
Thanks,
My System

  • I love PSUs! I also love ASEA! (they're unrelated)

Believe it or not, all you have to do is make a simple change in the Registry.

 

So, switch back to AHCI first and then follow these instructions (source):

 

Quote:

Change from AHCI to IDE Mode after Installation

Instruction:
 

  • Exit all Windows-based programs.
  • Press [Win] + R or take the RUN option from the start menu.
  • Now type regedit there and press Enter Key to open up the Registry Editor Window.
  • If you receive the User Account Control dialog box, click Continue.
  • Locate and then click the following registry subkey:
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic es\Pciide
  • In the right pane, right-click Start in the Name column, and then click Modify.
  • In the Value data box, type 0 [3 is default], and then click OK.
  • On the File menu, click Exit to close Registry Editor.
  • Restart your computer
  • Go to BIOS and enable IDE, Save & Reboot
  • Another restart will be required to finish the driver installation.



Alternatively

Just download this Reg File and double-click to implement IDE on your Windows-based computer.
Just remember to do the BIOS switch as well when you reboot.

 

 

 

When you're done, follow these instructions to go back to AHCI mode:

 

Quote:
Change from IDE to AHCI Mode after Installation

Information: AHCI stand for Advance Host Controller Interface. AHCI is a hardware mechanism that allows software to communicate with Serial ATA (SATA) devices (such as host bus adapters) that are designed to offer features not offered by Parallel ATA (PATA) controllers, such as:
  • Hot-Plugging
  • Native Command Queuing (NCQ) -might improve computer/system/hard disk responsiveness, especially in multi-tasking environment

You can read more about AHCI mode HERE

Instruction: There is one way to fix this, although you need to have knowledge of registry editing.
The detailed steps from Microsoft website are as follows:

  • Exit all Windows-based programs.
  • Press [Win] + R or take the RUN option from the start menu.
  • Now type regedit there and press Enter Key to open up the Registry Editor Window.
  • If you receive the User Account Control dialog box, click Continue.
  • Locate and then click the following registry subkey:
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic es\msahci
  • In the right pane, right-click Start in the Name column, and then click Modify.



  • In the Value data box, type 0 [3 is default], and then click OK.


  • On the File menu, click Exit to close Registry Editor.
  • Restart your computer
  • Go to BIOS and enable AHCI, Save & Reboot
  • Another restart will be required to finish the driver installation.


Alternatively

Just download this Reg File and double-click to implement AHCI on your Windows-based computer.
