Upgrading 1809 to 1909 - mysterious problem.

Hi,

The problem with hardlink is back!

Inside Windows run DISKPART and type the command list volume, post the result please.
 
Yeah, i have a lot of drives

Code: 
DISKPART> list volume

  Volume ###  Ltr  Label        Fs     Type        Size     Status     Info
  ----------  ---  -----------  -----  ----------  -------  ---------  --------
  Volume 0     I   EVO860       NTFS   Partition    931 GB  Healthy
  Volume 1     D   Clean_Win10  NTFS   Partition    232 GB  Healthy
  Volume 2                      FAT32  Partition    100 MB  Healthy    System
  Volume 3     E   win2k        NTFS   Partition     15 GB  Healthy
  Volume 4     H   OBLIVION     NTFS   Partition    277 GB  Healthy
  Volume 5     G   DATA         NTFS   Partition    638 GB  Healthy
  Volume 6     S   Constellati  NTFS   Partition   1863 GB  Healthy
  Volume 7     F   Storage      NTFS   Partition    931 GB  Healthy
  Volume 8     C   x64          NTFS   Partition   1862 GB  Healthy    Boot
  Volume 9     J   ESD-USB      NTFS   Removable     14 GB  Healthy
 
Wait, i just realized. That UEFI partition (volume 2) is on a different drive, where i have installed clean 1909. My old main drive doesn't have UEFI partition.
 
Can you disconnect all the drives except the main drive and post the result of:

DISKPART
select disk 0
list partitions
list volumes

The Windows 10 installation say your system is UEFI but I'm not seeing the usual volumes!
 
On top of that the disk is still in MBR mode. It seems that the upgrade from 7 to 10 didn't changed any of that. So, how do i fix all of that ?

Code: 
DISKPART> list partition

  Partition ###  Type              Size     Offset
  -------------  ----------------  -------  -------
  Partition 1    Primary           1862 GB  1024 KB
  Partition 2    Recovery           990 MB  1862 GB

DISKPART> list volume

  Volume ###  Ltr  Label        Fs     Type        Size     Status     Info
  ----------  ---  -----------  -----  ----------  -------  ---------  --------
  Volume 0     C   x64          NTFS   Partition   1862 GB  Healthy    System

Click to expand...

The upgrade never changes that, it maintains the same partition layout.

Did you do changes to the partitions? I don't see a System Reserved Partition but its possible to install Windows 7 without creating one...

I would try to do the upgrade to Windows 10 1909 with only one disk to see what happens.
 
I've already tried to upgrade with only one drive connected. Now I've found about MBR2GPT and used it to convert the disk to GPT. It now has EFI partition. After that I've tried to upgrade with only this drive connected. Alas, still the same result. And I thought we found the root cause :(

Code: 
DISKPART> list partition

  Partition ###  Type              Size     Offset
  -------------  ----------------  -------  -------
  Partition 1    Primary           1861 GB  1024 KB
  Partition 2    System             100 MB  1861 GB
  Partition 3    Recovery           990 MB  1862 GB

DISKPART> list volume

  Volume ###  Ltr  Label        Fs     Type        Size     Status     Info
  ----------  ---  -----------  -----  ----------  -------  ---------  --------
  Volume 0     C   x64          NTFS   Partition   1861 GB  Healthy    Boot
  Volume 1                      FAT32  Partition    100 MB  Healthy    System

Repeat the steps from post #30, lets see if this time every command works.
 
Hi,

Don't know why you are seeing that error on newly created partitions!

Some people reported success correcting the boot by booting the computer using the DVD/flash drive of Windows 10 and by doing this:
  • When you see the Install Windows page, tap or click Repair your computer to start the Windows Recovery Environment.
  • In the Windows Recovery Environment, on the Choose an option screen, tap or click Troubleshoot.
  • Tap or click, advanced options and then click on Startup repair.
 
Yes, that is exactly how I'm doing this (my BIOS uses F8 for boot menu, and I cannot reliably enter Windows boot because of that)
 
On the default configuration Microsoft removed the F8 boot option from Windows 8 and higher so is not a problem because of your bios key.

I know you are accessing the Windows Recovery Environment this, before accessing the command line there is an option to do a automatically Startup Repair under Troubleshoot try that.

Can you post the log?

I think it can be found on \windows\system32\logfiles\Srt\SrtTrail.txt
 
It seems that the system didn't find any problem with the boot so it didn't try to change anything...

When you boot from the flash drive, access the Recovery Environment and using Diskpart mount the Volume 1 as V: can you access cd /d V:\EFI\Microsoft\Boot\ create a new folder inside and delete it after?
md test
rd test
 
Welp, that was quite an adventure.

1) Rebooted, tried your write test (it works). Tried fixboot and suddenly it works too! Run bcdrebuild, and then realized that I booted with extra drive containing clean 1909. Greeted with

Code: 
The requested system device cannot be identified due to multiple indistinguishable devices potentially matching the identification criteria.
Oops.

2) Shutdown, remove extra drive, start command prompt. Fixboot doesn't work anymore. Write test works. Run bcdrebuild, got another error

Code: 
The requested system device cannot be found
Oops again.

3)Shutdown, reboot. Guess what - BCD not found, cannot boot.

4) Reboot to command prompt, assign letter to EFI parition, format, manual bcdbuild. Reboot and back to square one.
