In short; I tried (as most people tell): Starting windows in secure mode, then 
boot into the BIOS and there set from RAID to AHCI, afterwards start windows 
as normal.

This setting in BIOS was existent some time ago, but now it is complete gone 
(this point is completele disappeared!)!!  I know that it is in RAID, because 
Windows told so: BUS form = RAID.

Yes. I am wondering, why the debian installer DVD does not see the nvme-
device. When I installed Debian_11 a year ago, it did see the drive. Of course 
I tried with this DVD again to reinstall, but today it does not see the drive 
any more (I suppose because of RAID).

I guess I am unlucky..... :)

Thanks for the help.
