@King Crimson:
Welcome to the Win-RAID Forum!

I don't know the exact reason why the NVMe SSD was not visible anymore after having loaded the Samsung NVMe driver, but it is never a good idea to load a driver during the OS installation, if a working driver for the same device (here: Samsung NVMe Controller) had already been integrated into the OS Image.
This is what I recommend to do:
1. Integrate just the MS NVMe Hotfix for Win7 into the BOOT.WIM and INSTALL.WIM of your desired Win7 Image.
2. Enter the BIOS and disable the options "Secure Boot" and "Fast Boot" and allow the BIOS to load UEFI modules while booting.
3. Let the tool Rufus create a USB Flash Drive containing your freshly customized Win7 image, which is ready for booting in UEFI mode.
4. Remove/unplug all other HDDs/SSDs except the target NVMe SSD.
5. Boot off your USB Flash Drive in UEFI mode and install the OS onto your NVMe SSD without loading any additional driver.

Good luck!

Additionally I need the HardwareIDs of the devices named "Standard SATA AHCI Controller" and "PERC H330 Adapter".
You can get them by doing a right-click onto the related devices and choosing the options "Properties" > "Details" > "Property" > "HardwareIDs".

But I thought running the system in secure boot to make sure that all UEFI devices are running in UEFI mode is best practice?

Welcome to the Win-RAID Foru,m and thanks for the link to the AMD AHCI driver v1.3.1.276 dated 04/01/2017.

So what's is better, last version or last date?

I can't boot with secure boot enabled. It just gives an automatic repair boot loop. I imagine I violated some secure boot parameter by using the OFNVME driver. Do you know how to reset this?

Also, for the OFNVME driver why would you need to install the winraid cert to your trusted CA cert store? Do these drivers use public certs as well?

@sinan:
The HardwareIDs of your on-board Intel SAT AHCI Controller verify, that your system has an Intel 100-Series Chipset (like my PC).
You can find the Intel AHCI drivers, which I recommend to use with such system, at the bottom of the start post of >this< thread.

Regarding the RAID driver for your PERC RAID array I cannot help you. Please look into the PERC Support pages.

@lior19:
I have downloaded your linked driverpack, but I was not able to find your announced AMD AHCI driver v1.3.1.276 dated 04/01/2017 within it.
Please attach the extracted "pure" 32/64bit drivers as *.ZIP or *.RAR archive and I will offer them within the start post of this thread.

@King Crimson:
What means "Already took care of it"? Were you able to solve the problem, that Windows couldn't see some of your other disk drives? If yes, what exactly did you do?


@kevindd992002:
None of the OFA drivers has been WHQL certified by Microsoft. This fact may be the reason, that you are/were not able to boot off your NVMe SSD with enabled "Secure Boot" option while running any OFA driver.
If you should not even be able to boot off your NVMe SSD in "Secure Boot" mode after having replaced the OFA driver by the generic MS NVMe driver or a WHQL certified third party NVMe driver, you should ask Microsoft. It seems, that the registry remembers everything (Once not trusted - forever not 100% trusted).
