Solved My working solution to Invalid Data Access Trap

Over the past week and a half, I must have tried about ten times to upgrade from Windows 10 to Windows 11. My first attempt was when Microsoft actually offered the upgrade through Windows Update. I got the INVALID DATA ACCESS TRAP BSOD at 29 %. At the second attempt,, the BSOD cam at 86 %, with the message 0xc1900101 - 0x400D error during MIGRATE DATA upon the SECOND BOOT. After that, Windows Update did not again offer to upgrade. I downloaded the ISO, ran it through Virtual CloneDrive. No luck. I downloaded the ISO to a USB drive, no luck either. I searched for solutions and tried all sorts of things that were suggested at various sites. I ran CHKDSK, SFC, DISM. I reverted the default user folder locations (such as the 'Documents' folder) to the C drive. Nothing worked. I disconnected my Microsoft (!) webcam and turned off my printer. All to no avail. I tinkered with DDU of Windows Repair Tool. I don't know whether it did anything, but all drivers were reset to default ones.

I gave up, reconnected my webcam, turned the printer back on and moved the default user folders back to the D drive. Somebody suggested running in save mode before upgrading, but that did not work either. Then I tried one last thing, which wasn't suggested anywhere. And I got the upgrade to succeed. What I did was changing the system configuration through msconfig to starting up selectively, with only loading system services and startup components. I disconnected from the internet.

After the upgrade completed, I was not able to connect to the internet, so I rebooted after changing back to starting up normally through msconfig. All I got was another BSOD. I used my Macrium Reflect recovery environment in order to restore this morning's Windows 10 system image. That did not work on account of 'insufficient disk space'. Eventually, I managed to get Reflect to repair the (what it said was) the Windows 10 boot loader. When I restarted, I found Windows 11 in all its glory. I connected to the internet and ran Windows Update. Since then I have changed some personalisation settings and have rebooted half a dozen times. Everything is working well .… I have successfully created another system image and I am creating another system recovery disk. But this last thing has now been running for three hours and still hasn't finished.

I do it too, Before upgrading to a new build I always go to Startup and disable all third-party applications. Also I disable any non-Microsoft service from msconfig. If you have a third-party antivirus disable it permanently or even unistall it before upgrade so it won't interfere and screw the upgrade process.

Thank you Willem Dubelaar for your post.

I was upgrading from a Dell T3600 running Windows 10 Pro to Windows 11 Pro moving it over to a Dell 7070 with Windows 11 on a 256 GB NVMe M.2 2230 SSD . I cloned the old drive to a 512GB SATA SSD successfully and plugged it into the 7070 and booted up the Windows 11 it has on the NVMe and successfully ran the MBR2GPT command prompt utility to convert from the old T3600 MBR format to the GPT format required to install Windows 11. I then booted into the BIOS and changed the boot order to boot the 512 GB SSD. That worked and I booted up the Windows 10 Pro and let it install all the drivers for the I5-9500 cpu Intel chipset and everything the Dell 7070 motherboard required. No problems so far. Then I created a Win 11 23H2 bootable flash drive, ran the setup on it, and proceeded to upgrade to Windows 11. All was normal on phase 1, then upon rebooting into phase 2 it went all the way to 87% and then BSOD'ed with the "INVALID DATA ACCESS TRAP" BSOD and reverted back to Windows 10. I uninstalled the AVG anti-virus and other non-essential utils such as the AVG Anti-Track, etc. Reran the Win 11 setup and still got the same BSOD at 87% of phase 2. I flashed the Dell BIOS, and made sure the Secure Boot and TPM were enabled. Still crashed at 87%. Googled more until I got to this post. Hmm... maybe I need to run MSCONFIG and set "selective startup". Did that, rebooted, reran the Win 11 setup, told it to keep programs and data, and walked away for awhile. When I can back a half hour later to check on it I was pleased to see the Windows 11 desktop (Win 10 didn't have a password set so it auto-signed in to the desktop). I checked and it is a fully activated Windows 11 Pro 23H2 OS. The Device Manager has everything correct, and running MSCONFIG shows that it is booting in "Normal" mode so I have sound, Internet, etc. so the upgrade appeared to be successful. I then ran the most important program, QuickBooks Pro, and it came up normally (whew). The only thing missing was Win 11 didn't see the 256 GB NVMe M.2 drive at all. rebooting and pressing F-12 to get the Dell startup menu showed both drives so the M.2 was there and not accidentally turned off, but Windows 11 was not seeing it. Rebooted back into the BIOS to see what other item needed to be changed. Ah ha, I needed to go into UEFI Boot Path Security and set it to NEVER instead of the default which is "Always,Except Internal HDD". Save and reboot and Windows 11 Pro sees the 256 GB M.2 SSD.
I still have no idea what driver in Windows 10 was BSODing the Windows 11 upgrade, but using the "Selective startup" option in MSCONFIG did the trick and I now have Windows 11 Pro running on the Dell 7070 with all programs and data.

Thanks again for posting this 2 years ago. It solved my headache over the "INVALID DATA ACCESS TRAP" BSOD.

You probably need some storage controller drivers before Windows 11 can see the other drive. Check in Device Manager to see if any device has a yellow ! meaning some driver is missing or not properly installed.

I've dealt with this BSOD before and its always due to some third-party software inferring with the migration part of the upgrade, more details here: Debugging Stop 0x4 – INVALID_DATA_ACCESS_TRAP

A buggy Intel tool. The most obscure Windows BSODs are caused by third party software the Windows installer can't read.
