Upgrading 1809 to 1909 - mysterious problem.

Code: 
SMART Extended Self-test Log Version: 1 (1 sectors)
Num  Test_Description    Status                  Remaining  LifeTime(hours)  LBA_of_first_error

Ok, good.

Check the BIOS of the machine and disable any option related with Virtualization, also deletes all the hidden folders created by the Windows setup on C: like C:\$WINDOWS.~BT, $WINDOWS.~WS etc.

Try to upgrade again without the internet connected and using the installation files from the flash drive.
 
Virtualization has been disabled two weeks ago. I start any new attempt running disk cleanup and then manually deleting hidden folders. Last two attempts has been with internet disconnected.
 
Ok.

From the log:
Code: 
2020-01-24 20:54:19, Error                 SP     CFinalizeCriticalBoundary::DoExecute: Cannot create hardlink betweeen C:\$WINDOWS.~BT\Sources\SetupPlatform.exe and C:\Windows\System32\OOBE\SetupPlatform\SetupPlatform.exe. Error: 0x000000b7[gle=0x000000b7]
2020-01-24 20:54:19, Error                 SP     CFinalizeCriticalBoundary::DoExecute: Rollback in system context will not be registered.[gle=0x000000b7]

The error just before the Rollback is about the hardlink, check if the folder C:\Windows\System32\OOBE\SetupPlatform exists, I don't have it on my system if you have rename it to SetupPlatform.old and try to upgrade. Collect the Setupact.log and setuperr.log to see if there are changes.
 
Hi,

This time the error is on a different file on the same destination folder!
Code: 
DoExecute: Cannot create hardlink betweeen C:\$WINDOWS.~BT\Sources\UNBCL.DLL and C:\Windows\System32\OOBE\SetupPlatform\UNBCL.DLL. Error: 0x80070050[gle=0x00000050]

Could it be that the flash drive contents is corrupt?? Do you have the Windows 10 installation ISO? if not I would recommend that you use the Media Creation Tool to create the ISO them mount the ISO by double clicking on it and try to install from the mounted ISO.
 
Removed DLL from C:\Windows, tried upgrade using fresh ISO extracted to a folder on a drive. Same result.

Run SetupDiag and post the log and files generated by the tool.

Don't extract the ISO if you double click the ISO file Windows 10 should mount the ISO in its own drive letter.

Now the log doesn't show any problem with the creation of the hardlink's.

Tried with mounted ISO - same result.
Click to expand...

I didn't ask to retry I was suggesting to mount the ISO instead of extracting.

Lets work on another problem present on the logs...

Please rebuild the BCD by following the instructions for Windows 10 on the following link
How to repair the EFI bootloader on a GPT HDD for Windows 7, 8, 8.1 and 10 on your Dell PC | Dell Portugal

Its important to execute all the commands till the last one bootrec /rebuildbcd

To do this you have to boot the computer from the flash drive.
 
Ok, thanks. I'm on a trip without access to this desktop. Will post update on Friday.
 
Hi,

Repeat the steps until 5 iii) where you exit DISKPART after assigning a drive letter like V:

next format the partition by typing:
format V: /FS:FAT32

followed by:
bcdboot C:\Windows /s V: /f UEFI

now the bootrec /FixBoot command should work
 
I assume that i need to replace "C:\Windows" with a proper driver letter of main windows partition ?
