Yes in the PE phase, after the failure, if you can press shift-f10, to open a cmd promt, the logs will be located in x:\windows\panther

I got my logs 2 times, once when I get the disk managment screen, and one after I delete my partitions and hit next to start the setup and get the error that says partition is not ready.
Thank you!Logs.zip

Just an update

This is the part that have to be investigated.

Code:

While the disk passes all validations, at this point for some reason, the process fails to get partition information.

Uh oh, I've trying googling those errors and I must be the only one with them.

Hi,

Sorry for the delay,

I audited every disk operations in your log, And it's makes me wonder why would. The message

PerformInstallDiskPreparationOps:Install destination is unallocated or unformatted; auto-preparing as necessary...

Appear... After doing..

ApplyDiskOperationUsingService: Formatting partition on disk [0] at offset [0x100000]; DC FS type = 0x3.
ApplyDiskOperationUsingService: Formatting partition on disk [0] at offset [0x100000]; DC FS type = 0x3
ApplyDiskOperationUsingService: Formatting partition on disk [0] at offset [0x1f500000]; DC FS type = 0x3

This part seems incorrect.

I don't think your OEM partition should have a drive letter assigned. And I think because it get C:\ might be part of the problem
the code I provided should not assign letters to the Windows RE partition type: 0x27 should remain hidden. A problem like that occurred in 2018 where windows would assign c:\ to OEM partition then proceeded to install windows on D:\

I don't know if this problem could occur in an unattended setup... But it sure looks like it...

I stripped down my XML and removed the letter.
It does give C:/ to windows partition atm, check the logs.
But it still does the same thing, Does not automatically partition unless I try to setup on the empty drive, and get the error.
Logs are after the error.
