Hi, Fix worked in my case. Thanks !
I followed those steps (from link submitted before) :
- Temporarily assign a drive letter to the System Reserved partition from the "Disk Management".
2) Open an elevated command prompt and run fsutil usn deletejournal /N /D X: where "X" is the assigned drive letter of the "system reserved" partition.
3) Remove the drive letter to the "system reserved" partition (which should remain without assigned drive letter).
- Launch the KB4474419 update
In my case, my system reserved partition is 350 MB large and was totally full.
Clearing the logs only cleared 40 MB (310/350). It worked anyway.
I have installed this system and several others myself using Windows installer. I perfectly remember that when you create partitions using this installer, it asks if you want to create a Reserved partition or not.
So I confirm that you can install Win 7 without any reserved partition using only the official tool (I've done this at least twice).
On earlier versions of the installer, the partition was 100 MB large only.
Sometimes I use Gparted to clear the disk before install. I had issues when trying to create Windows partition in Gparted before installing. The installer didn't accept the partition if I remember correctly.
Anyway, looks like you can create this partition without re-installing Windows.
