You can download and extract this Intel VROC driver to a USB drive.  When the Windows installer gets to the screen to select intend boot drive, select load driver, browse to extracted folder and install it.  NVMe SSD from flexbay will be visible.

@Chino de Oro​ hi thanks for the reply I have already tried this and I can't seem to get it to detect the drive even then.

I will try it again later just incase I did it wrong thanks for the reply

cheers

@Chino de Oro​ hi again another update I tried this driver you linked to and I get this BSOD from the windows installer

@mazzinia_​ hi thanks for the reply ill try this tomorrow and post back my findings.

thanks 

After downloading the driver to a working computer, double click to run and select extract instead of install.  In the extracted folder, open F6 folder and copy only the second file IntelVROC_f6_iaVROC_win10_64 to the USB drive.  During Windows installation, select load driver then browse to that iaVROC driver to install.

I had a similar problem on my Precision T7920. The only way I was able to get around it was to install the OS on a 2.5" SSD , then clone that drive to the NVMe M.2 drive.

@Chino de Oro​ ive tried his and same issue persists it wont load the driver and then i get the same BSOD

@kenact71875e​ im starting to think this may be the only option to use a 2.5inch ssd and clone it over

@mazzinia_​  hi again this worked flawlessly and then I updated it to the latest version and now it’s running perfectly.

thank you for your help..
