SCCM Windows 11 Role Up

[T_Lister]

Installing a blank OS, no problem at all on both physical and virtual machines. Doing a role up from 10 to 11 on the other hand is proving somewhat annoying as it gives me the glory code of 0x80004005 that's not very helpful. So digging around logs and forums I'm currently under the belief that the issue is compatibility. Running a cmd "SETUP.EXE /Auto Upgrade /NoReboot /DynamicUpdate Disable /Compat ScanOnly" tells me that my VM won't role up because of TPM 2.0 not being there. I have found a number of Reg hacks that can tell my computer to ignore the pre-req, TPM/SecureBoot/CPU etc, however it is still failing our on me with the same errors.

 

These are the error messages that I have been getting.

 

Windows Setup failed with hexadecimal exit code 0xC1900200 (decimal 3247440384). To identify the type of issue, lookup it against the table of known values of Windows Setup errors online.

Failed to run the action: Upgrade Operating System. Error -2147467259

Failed to run the last action: Upgrade Operating System. Result -2147467259. Execution of task sequence failed.

 

What am I missing?
