Windows 10: Windows 10 error - INACCESSIBLE_BOOT_DEVICE trying to change to AHCI mode for mother upgrade

Mother Intel with G41 chipset (ICH7 ide controller). Stuck on IDE mode.

Tried to reset storeAHCI, iaStorV as per various sites:

Also Safe mode minimal boot:

And automatic repair using ISO also fails as suggested here:

Still INACCESSIBLE_BOOT_DEVICE on boot, so I'm still stuck and can't upgrade to a newer mobo without IDE mode because of that. Any ideas?

Windows Will Not Boot After Trying To Change To AHCI Mode

I have looked at the How to Enable AHCI in Windows 8 After Installation link you provided.

[By the way, after you paste in a web address press the spacebar and it will turn into a hyperlink so people can get to where you are pointing -

http://www.ithinkdiff.com/how-to-enable-ahci-in-windows-8-after-installation/ ]

All their methods were about steps to take in Windows 8 Registry before changing the BIOS. They were not an alternative to the BIOS. If you have no such setting in your BIOS then you cannot use AHCI. All BIOSes differ but here is a sample AHCI entry to
help you check for anything similar -

• I think you should leave any fiddling with AHCI now and focus on getting the system in working condition first though.
• If SFC & DISM did not help you resolve this problem then I suggest that you restore your system image again.
  
• If you no longer have it then make an
  installation USB and run a
  Repair install [also called an InPlace upgrade].

Once you have a working system again & only if you have a ACHI setting in your BIOS -

• Make a new system image before any more experiments.
• If you do find an AHCI setting in your BIOS then you could try just changing it and seeing if the system still works. Another user did just that and found that it all continued working without anything else having to be done.
  
• And if it doesn't work for your computer then you could
  either go back to the BIOS, reset it then give up the idea or do a clean installation with AHCI set and see if that works.

Change SATA mode to AHCI from IDE

I was able to change it now (I also had some issues with NICs so I decided to reinstall my PC but I wanted to keep my files, programs, settings .... ). Here is how:

• Lunch application "setup.exe" from path "c:\$Windows.~WS\Sources\Windows\" (simply running upgrade to 10 again, but this time from windows 10)
• After first reboot, change SATA mode to AHCI and let Windows finish upgrade
• Everything should be fine now

I am now running my disks in AHCI mode now and even don't have (so far) issues I had before.

 

Changing IDE to AHCI Mode

Hi guys, I thought i might put this up for people that also might have missed this setting to get AHCI mode working on your motherboard.

A mate of mine decided to look into it and found a Windows Vista/7 fix so you can enable AHCI mode in your BIOS without the system blue screening, like it does for most computers that are already set on IDE mode.

Now most of you guys might already knows this but I didn't and all my computers where set on IDE mode and when I would change it to AHCI it would just crash when booting so I just thought oh well it don't work and never bothered with it again. But it seems if you set AHCI mode BEFORE installing Windows you wont have this issue, but if you did not set it before then running this Fix will fix your problem *Smile

Ok run this Fix > http://support.microsoft.com/kb/922976 then go to your BIOS, change your settings from IDE mode to AHCI mode, save and exit, boot into Windows, it will then install all the drivers that you need for this Mode. Once its finished it will ask you to reboot, reboot and your done *Smile

Made a big difference for me in boot times and file transfer times, everything sped up alot.
