I have a Workstation 5820 using Windows 10 Pro for Workstations and approved for upgrade to Windows 11. My boot disk is NVME disk.
However, when trying to upgrade Windows 10 to 11, Windows does not start after reboot, due to a Blue screen due to a problem with "iaStorE.sys" (IRQL NOT LESS OR EQUAL). So, instead of doing an upgrade, I decided to FORMAT the disk and start an installation from zero. And the same problem always occurs. I've tried all versions of intel VROC (6.2, 7.0, 7.6 and 8.0 - 8.0 doesn't even work with Windows 10, same error) and in all I face the same problem. I am saying this, because i need to load the drivers IASTORE and IAVROC at the begging of Windows installations because, if i dont do this, the installation cannot see nvme disks and can see only SATA disks. However, when I install from an SSD disk (SATA), either by Upgrade or by clean installation, strangely, Window 11 installs and works.
But I don't want to start Windows from an SSD and yes from an NVME disk.
Has anyone had this problem or have an idea of how to solve it?

I think if @Chino de Oro hadnt problems (win11 upg), or his bios was in another mode, or if was in RAID mode the C600 AHCI installed driver was not being used by windows...
Quick question. Did you retain the option to revert , when doing the initial upgrade ?
This said, this sounds pretty similar to what one 7820 user reported as issue around 5 / 7 days ago, and in his case using one of those iastor drivers ended bricking the motherboard, practically.
I think Dell support should pitch in openly, not in private, about this issue. There will be quite a few 5/7820 7920 units getting this upgrade, and given the cost of these units, the upgrade should have been first checked by dell itself using test systems.
When I upgraded from Windows 10 to 11, after a few unsuccessful reboots, the system automatically rolled back the upgrade returning the Windows 10 version. However, if the installation is carried out from scratch on the NVME disk, there is nothing to do but reformat and reinstall windows 10. However, the strangest thing is that on the SATA drive the installation works perfectly. But if I have a computer with two NVME DISKS it makes no sense for me to use a much slower SSD as the boot disk.
ps: Now i am using Windows 10 Pro for Workstations because i reffuse me to use Windows 11 in SSD disk. And even if you are using an SSD disk, windows 11 does not see NVME disks because you simply CANNOT INSTALL VROC DRIVERS or you will get blue screen!
Apparently it's a problem with the Precision line (5820/7820/7920). As Dell is selling new Windows 11 machines they probably changed something on the motherboard which would be unacceptable (like the TDP problem that exists)...
@Flavius Aetius thanks ... at least this confirms that if this kind of issue arises, the system eventually reverts and works normally back on win10 ( honestly I would hate to have to reinstall due to having to add back all the programs. ok that i've a veeam incremental backup.... )
And yes, not being able to boot nor to use the nvme is a deal breaker.
It is curious that Dell has been selling Precision Workstations with Windows 11 for months and the same models that were equipped with Windows 10 have problems. Either Dell has modified some internal component or Dell is using specific drivers on these machines and is not making it available to the general public.
Intel® Virtual RAID on CPU (Intel® VROC) and Intel® Rapid Storage Technology Enterprise (Intel® RSTe) Windows* Driver for Intel® Server Boards and Systems Intel® Chipset are not Dell drivers and are not supported here.

Sounds like a problem with Intel-RST.
Try setting BIOS to UEFI, AHCI, SecureBoot.
Clean install Windows to a completely blank disk. Never install Intel-RST or eRST.

Hello @Flavius Aetius , I received the notice to upgrade to Win 11 but I only want to run as testing so I installed it on a second drive in the flexbay. I run Win 11 for workstation with NVMe SSD. Here is the driver I used for installation. Hope this would help.

Exactly...
