Convert Sata Mode from AHCI to ISRT without reinstalling OS

Hello All,

On One of my dell laptops....

I tried Installing OS using IRST mode on in Sata Operations in BIOS.. but OS wasn't able to detect disks while Installing it. Even diskpart showed no disk available.

So I installed OS after changing sata mode back AHCI ..

I have a mSATA of 60GB and an HDD of 1 TB ...
OS got installed on 1TB hdd....

But the now the OS is not utilizing the SSD of Cache management.
If I change the sata mode back to Intel Smart Response tech (ISRT) the Computer goes NO BOOT
Is there a way I can change ISRT back ON in BIOS without Reinstalling OS..

Any help would be appreciated.

I`m no expert on those drives, but, I don`t think it`s gonna use the cache if you installed windows on the hard drive. Is it 2 separate drives ?

As far as the other, I`m not positive but you usually can`t switch from AHCI to the other once you install the OS, but then I`ve only seen 3 options in a bios, AHCI, IDE or Raid.

Others with the option you speak of will have to answer on that.

NO Problem resolved it by myself... Needed a Lettle tweak in Regedit..
FYI.. you can switch from AHCI to other modes (if available) even after installing OS..
Please google IRST and ISRT
