IRST issue

[CheeseToastie]

Intel Rapid Storage Technology problem

Hello, so basically my problem is, in my PC I have a 1tb m.2 and a 2tb m.2. Windows is installed on the 1tb. In the bios my 1tb shows as normal but my 2tb shows up as 2.1GB if IRST is disabled. If IRST is ENABLED then it’s shows up in the BIOS as 2048GB but when I go to boot windows it crashes and I get the inaccessible_boot_device error.

I cannot for the life of me boot into windows with both the drives working and recognised. If I boot into a recovery media like HirensBCD then both these drives show up as their correct sizes etc but as soon as I try to boot normally then I get the crash and can’t do anything without disabling IRST.

Any ideas? If any information will help just let me know

Why do you think you need IRST?
I thought it has been abandoned; https://www.intel.com/content/www/us...intel-rst.html

It was only beneficial if you have RAID setup.

I have always removed that service and never seen an issue.
