I don’t have msahci in registry editor

2022 works like a charm..thanks to this channel!

My true hero

I had value 3. What that means?

Thanks!,It really worked!

Si esto funciona te debo una chela, ahora te digo que sucede...

won't work for me ?

Avery belated thanx.

Omg it freakin work! Thanks finally

I wonder if you still read these comments. How do you do this if you have two bookable drives with Win-7 and Win-XP If you switch it back in the bios will it still boot. I'm not using a boot manager, I just use the F12 key at boot-up to select which drive to boot from as each drive has it's own operating system.

i'm using intel dual core windows 7 and bios not showing AHCI

My BIOS still only shows 2 options, IDE and RAID. I researched some more and found my other people with my motherboard who also couldnt get AHCI even after BIOS updates and a lot of tinkering. I think ill just leave mine...

I installed a Samsung 850 pro, just using the migration software to copy old drive to it. Looking through the Samsung magician app it tells me I need to enable achieve for optimum performance. Currently it is in raid mode when I look at the bios. I have numerous times changed the msachi to value 0. Currently set at 3. I reboot then enter bios and change sata to ahci. Upon reboot it just keeps looping around Windows startup, with a flicker of bluescreen then tries to boot again and again. If I renter bios and change back to raid mode it boots just fine. I have also looked at changing the iastorv to 0 but it already is. Any ideas????Laptop is an old dell m4500. Thanks

it worked, great!!!

it worked. thanks a lot !

this worked, but my value was a 3 and not a 1 like yours. but i made it 0 and it worked. thanks!

Thank you sir, this helped me out :)

Does this work in Windows 8.1 64bit? (I can't fint the msahci folder)

I changed the value from 3 to 0 and it worked like a charm! Thanks a lot!

This actually worked for me. When I restarted my comp, the ahci drivers started installing and required another restart.
Using windows 7 - using crucial MX100 SSD*
Thank you Techneek.

Thanks awesome video. I have changed it for my SATA drive, now I can buy the SSD.

Thanks

dumb question but where do you get the drivers ? or is it auto 

ur da best works like a charm for my Samsung Evo 840!

I don't have AHCI in my bios, what should I do ? I'm lost !

When I changed it to AHCI and it goes past the boot screen it just goes to a black screen and my computer wont stop beeping. Changing back to IDE lets my computer boot normally. ANY HELP?? ):
