XPS 15 7590, Memory Integrity on causes an inaccessible boot device

We don't have any official information yet. I don't know about the others, but Dell will lose me as future client on a next purchase. This XPS have many minor problems that I just adapted myself to live with.

News ?

I am having the same issue and have tried everything that I can find on internet.  Please advise.

Hello,

I did it, everything is green, except one thing:

"====================== Step 3 OS Architecture ======================

Unknown architecture

Machine is not Device Guard / Credential Guard compatible because of the following:
Unknown OS, OS Architecture failure.."

What now?

I found a solution to the Unknown architecture:

"

Solution

Change the code in the CheckOSArchitecture function in the \DG_Readiness_Tool_v3.6.ps1 script as following

from
OSArch=(gwmi win32_operatingsystem).OSArchitecture

to

OSAch=((gwmi win32_operatingsystem).OSArchitecture).tolower()

then the script just works fine."

After that, everything works fine with no problem. I have no errors, still the update does not work!

I ran the tool and found one driver for the Focusrite Scarlett 2i4 that was incompatible. Focusrite has a newer driver available on their website (June 2022) that solved the problem after a rerun ".\DG_Readiness_Tool_v3.6.ps1 -capable -hvci"

But unfortunately, the upgrade to Windows 11 22H2 still fails.

I have premium plus warranty till 2024. I will sent back my Dell and demand a fix. If not possible, I will return.

Days after running the DG_Readiness_Tool_v3.6.ps1 tool I'm confronted with many BSOD's that I have had never before!

Going back to a restore point from 3 days back in time. My goodness, what I ride.
Come on Dell, please provide a fix soon or at least let us know you are working on it.

Hi... tonight in win update "Windows 11, version 22h2 is available" appeared....what should I do?

do i proceed or wait?

thank you all..

My Dell XPS 15 7590 also went into repair loop after enabling those virtualization settings and restarting. When I Disable Virtualization I/O from BIOS, it seems like it will get solved but it asks for Bitlocker recovery keyI don't have this key.

Please there must be another solution. I have very important data on my drive!Is there any other solution where we won't need Bitlocker key!?

I was part of the insider program for Win 11 22H2 and this problem started early May with a new released build. I then tried to do a clean install resulting in the same problem. Disabling secure boot in the bios solved the installation bug. 
So it coud well be it is on the Microsoft side.

@F-bitlocker You should be able to get your bitlocker recovery key from your MS account, if you setup the computer using an MS account.

I have the exact same issue. Is there a solution yet?

Short answer NO. There is a work around, but with complications regarding BIOS settings. See thread here.
