"inaccessible boot device" after updating pci root complex (windows 11)

Question

Hello

I am having an issue with those two driver updates from Intel

PCI\VEN_8086&DEV_A70DDesc%=Needs_PCI_DRV,PCI\VEN_8086&DEV_A70D "Intel(R) PCIe RC 010 G5 - A70D" ver 10.1.49.7

PCI\VEN_8086&DEV_A74DDesc%=Needs_NO_DRV,PCI\VEN_8086&DEV_A74D "Intel(R) PCIe RC 060 (x4) G4 - A74D" ver 10.1.49.7

After updating those drivers from the default Microsoft PCI Express Root Port driver I get a blue screen with the error "Inaccessible boot device"

Safemode won't work and I tried diskpart the "active" command doesn't work on GPT disks only on MBR

After the update, it seems that even diskpart doesn't recognize the attributes of the disks like it was before not at all

A system restore is needed to remove those inf updates and go back to the normal Microsoft PCI Express Root Port driver and the system goes back to booting as it did (without the intel inf updates)

from my understanding, those drivers must be installed during the OS installation process by adding the drivers to the setup.

can it be done after windows got installed with a normal Microsoft driver and not the intel inf one?

Please guide me on how to get windows to boot after updating to intel inf 10.1.49.7 (from Intel inf ver 10.1.19284.8351)
Thanks in advance Beni.

Hello there,

The INACCESSIBLE_BOOT_DEVICE bug check often occurs because of a boot device failure. During I/O system initialization, the boot device driver might have failed to initialize the boot device, typically a hard disk.

File system initialization might have failed because it didn't recognize the data on the boot device. Repartitioning the system partition, changing the BIOS configuration, or installing a disk controller can also cause this error.

This error always occurs while the system is starting. This error frequently occurs before the debugger connection is established, so debugging can be difficult. The OS might not be accessible and the error logs might be empty, as the OS hasn't booted far enough to start those subsystems. The following sections explain resolutions for both situations, if you're unable to boot Windows and if you're able to boot Windows. https://github.com/MicrosoftDocs/windows-driver-docs/blob/staging/windows-driver-docs-pr/debugger/bug-check-0x7b--inaccessible-boot-device.md

Hope this resolves your Query !!
