    I dont know if the IRST from the the link above I used is the right one. What is in my extracted files doesnt even match yours.

    OK, so i downloaded the IRST on to the Rufus USB, but it is still not showing any driver option when i go to Load Driver. Do i need to move the inf files you were talking about out of the IRST folder and up to the Rufus level?

    Try this also, as the same has happened to me when I just put both folder of the IRST driver and tried to install Win-11.

    So do this, when you put the PH315-55s IRST Utility_Intel_19.0.1015.0 into the bootable Win-11 USB only put the last folder of the IRST as this IRST driver is within 2 folders, so only put the last folder, as Win-11 in some instances only opens 1 folder and thinks that there is no IRST driver as it can’t get access to the 2nd folder where the drivers are, so try that, as the Win-11 installation should recognize the IRST driver and your M.2 SSD boot drive, to install Win-11 and continue the installation.

    If the above doesn’t work, then go to Intel “Unable to Detect the Drive When Installing a New Windows* OS on a 12th or 11th Gen Processors Device” and use their ne=methos to install the IRST driver. Good luck.
