hello the oven

I have 5 normal hard drives in my Computer
But I also have a Samsung SSD 970 EVO Plus 2TB NVME M.2 SSD

I clicked in winbuilder on export host drivers and copied the exported drivers to the drivers folder Custom \ x64 \ Drivers

And if I press the big blue button to start building, everything will be fine
But if I make my Iso with rufus and put it on a USB stick to boot from

When I get into my Windows Pe and everything is loaded and I click on this PC to see my disks
Then they are not there

If I then go to computer management and then to disk management then I see that all disks are offline

I can manually bring all my 5 disks online by clicking with the right mouse button and then I can give the disk a letter but this is not the case if it has to work

But the Samsung SSD 970 EVO Plus 2TB NVME M.2 SSD that is not available online so I cannot access it in my Windows Pe DVD
If I want to try to bring this disk online, I get an error message
this is my Windows disk here is my installed windows 10

I have seen that in the register of my Windows Pe DVD the value is set to 3 every time it automatically becomes 0

That is why my discs are offline in my Windows Pe DVD

below you have some explanation what i mean i found this information on the internet

_______________________________________________________________________________
This information is stored in the registry under

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\(disk\device\path)\Device Parameters\Partmgr

There is a DWORD value named "Attributes" with the following values:

0 = Online

3 = Offline

(decimal or hexadecimal are the same)

Device paths tend to contain some part of the device bus and name. The device path on my test system was SCSI\Disk&Ven_&Prod_LITEONIT_LMT-256\4&35b1cb49&0&040000.

So the generalised steps are:

Boot into the recovery environment
Mount the registry offline.
   
Edit the registry key. In an offline system there is no "Current" ControlSet so change all of ControlSet001, ControlSet002, etc as appropriate.

Greetings Dennis

I don't know if it has something to do with the San / Disk Policy but it sure looks like it.
Normal operation is 0,

boot your PE open a CMD box and type

Diskpart <enter>
automount <enter>

You will get the current status... You will probably get that it is enabled...

You can force Mountmgr to mount disks with the registry.

Use the addition plugin
RegWrite,HKLM,0x4,tmp_System\ControlSet001\Services\MountMgr,NoAutoMount,0

But... Your issue can be Driver related because Windows default is to load all new disks.
Can you try it on another computer to confirm that the current build you have behaves correctly.
Try unplugging the SSD and do a test boot see if the others are mounting properly,
Make sure that the exported Drivers Matches your build. Try a build without integrated drivers.
If it works, Unplug all other disks and troubleshoot the SSD alone.

Also Verify that /System Tools/Write Protect Tool is Disabled or not set to Run at Startup
