Welcome. I am at war with the performance of my disk. I thought that at the beginning it would be good to switch to AHCI. I fired up the registry, found what I needed by supporting the windows support page. I did exactly as it was on the site, resets my computer, I change the mode from IDE to...

Something you did wrong, it's a pity you didn't even specify what system you have, not to mention what exactly you changed in the registry.

I completely forgot. Already corrected.

The change from IDE to AHCI is done in the BIOS and then installed Windows. A change on the installed system results in a blue screen. First of all, show the SMART of this disk.

Change the path yet HKEY_LOCAL_MACHINE / System / CurrentControlSet / Services / iastorV Start at 0 Then switch to AHCI in Bios. Found: We turn on AHCI

It's worth changing all three: HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ msahci HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ iaStorV HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ iaStor

Paste into notebook, save as Fix.reg and run: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ msahci] Start = dword: 00000000 [HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ pciide] Start = dword: 00000000 [HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ iaStorV] Start = dword: 00000000 [HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ iaStor] Start = dword: 00000000 [HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ atapi] Start = dword: 00000000 After doing this, change the bios to ahci and try to boot the system.

As for the registry editor, the script does not work: / I changed these values manually and did not help either. I'm starting to be in favor of a format Only that during the previous installation of windows in AHCI mode, after creating the partition, I clicked Next and I got some error, I don't remember what

Probably about the lack of disk controller drivers that you need to specify on the pen.

Welcome. I am at war with the performance of my disk. I thought that at the beginning it would be good to switch to AHCI. I fired up the registry, found what I needed by supporting the windows support page. I did exactly as it was on the site, resets my computer, I change the mode from IDE to AHCI, the computer reboots and I think to myself WOW I made it !. At the moment I got in the face of life moments after the animation of the windows logo appears blue screen.

ASROCK B85m motherboard.
Edit.
Windows 7 Home Basic 64 bit. In the register:
HKEY_LOCAL_MACHINE / SYSTEM / services / msahci. There in the Name column right click on Start -> Modify and changed the value "Value data" from 3 to 0.
Only this. I was afraid to touch the register for obvious reasons ...

Change the path yet
HKEY_LOCAL_MACHINE / System / CurrentControlSet / Services / iastorV
Start at "0"

Then switch to AHCI in Bios.

Found: We turn on AHCI

It's worth changing all three:
HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ msahci
HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ iaStorV
HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ iaStor

Paste into notebook, save as Fix.reg and run:
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ msahci]
"Start" = dword: 00000000

[HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ pciide]
"Start" = dword: 00000000

[HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ iaStorV]
"Start" = dword: 00000000

[HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ iaStor]
"Start" = dword: 00000000

[HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ atapi]
"Start" = dword: 00000000

After doing this, change the bios to ahci and try to boot the system.

It is not surprising that blue screens crashes ... Only that I am not an expert but it seems to me that after switching to AHCI some installer should be launched but smaller. Where to get these drivers?

Have you ever visited the producer's website? You have everything there including controllers for the controller! > "SATA Floppy Floppy Disk Image Image ver: 12.8.0.1016"

The controller is intel, the drivers are also on the Intel website, you can integrate them with the installation CD, then you will not need a diskette.

In the end I was forced to format. The problem was the lack of drivers. Thanks to everyone for the time and reading of my scribbles.

Topic summary

The discussion revolves around a user attempting to switch the SATA mode from IDE to AHCI on an ASROCK B85m motherboard while running Windows 7 Home Basic 64-bit. After modifying the registry settings to enable AHCI, the user encounters a blue screen of death (BSOD) upon reboot. Various responses suggest checking and modifying additional registry paths related to AHCI, including msahci, iaStorV, and iaStor. The user is advised to ensure that the necessary disk controller drivers are available, as the lack of these drivers is likely causing the BSOD. Ultimately, the user resorts to formatting the system due to persistent issues, confirming that the absence of drivers was the root cause of the problem.
