    Hi,

    I had error when I performed update Intel rst drivers. Now my windows 11 won't boot. I have inaccessible boot device error. I can't boot in safe mode and when I choose command prompt sfc /scannow can't perform successfully.

    How can I fix this without clean install?

    Thank you very much for help. I watched few guides already but still I'm unable to fix this.

    Try a boot repair or an earlier restore point.

    I didn't think you would have. Open up command prompt, locating the driver and delete it?

    I need to probably install correct driver from USB drive. I don't know which files I shoud remove because it was setup installer. I don't understand why I can't boot in safe mode.

    Take drive out and repair it on another PC.

    use command prompt when you are in recovery mode. (if you cant boot into recovery mode somehow than create a bootable windows installation media that matches your windows version or higher.) find the drive that OS installed then delete all folders begins with "iastor" in "C:\Windows\System32\DriverStore\FileRepository".. and find the folder that begins with "iaahci.inf" there may be another IntelRST related files begin with iaStor delete them too.. dont touch other files like iaahcic.inf or iaAHCIC.cat.. and RESTART

    hrm, perhaps startup repair is more capable these days than i give it credit for.

    Startup repair never fixes any boot issues. Pretty much useless.
