I am gonna try and will post here. Thanks.
I found that but not in C:\ partition, it was in "System Reserved" partition.
sda1 for System Reserved and sda2 for C:\, in my case
File location: /mnt/sda1/Recovery/WindowsRE/Winre.wim
But it is only 284 MB.
I am trying to find out if there is a difference between clean installation and Reset PC. And in that case clean installation looks more clear. How come just 284 MB is gonna install the whole system from nothing?
I've been trying to find the answer for the same question for couple weeks. With no success, however.
I did reset PC on my laptop yesterday and it did not even asked for a recovery image. I know that I have no recovery partition on the drive (bought mSata SSD) nor registered recovery (same as this guy: Reset Windows 10 - Page 3 - Windows 10 Forums )
Reset worked very well but there was a one difference between clean install from the USB Stick:
- a driver for the USB controller was not installed properly when I did "reset PC", other drivers were installed automatically. When I used clean install from the USB stick I had no problem. It could be because of the internet connectivity during install (LAN).
I may try it again without the internet.
OK, here it is:

If the system is "good enough" then no image is needed and system is rebuild from the current files (including windows 10 updates !)
REAGENTC.EXE /setosimage /path r:\Recovery /index 2
The path in red is to the folder containing the install.wim file. Index 2 is Home. Use Index 1 for Pro. Also the recovery partition that you copy the install.wim file to only has to have a temporary drive letter to run the command. After the osimage location is set in reagentc (verify with reagentc /info), you can remove the drive letter from the recovery partition.
Another advantage to having the install.wim file on the hard drive is that you can use the dism restorehealth command and point it to the install.wim file for the source (but your recovery partition has to have a drive letter for that).
And install.wim file should be located out of the system drive, right?
If you have a recovery partition already with WindowsRE on it, you can use MiniTool Partition Wizard to resize partitions to make room in the recovery partition to hold the install.wim file.
Having the install.wim file is absolutely NOT necessary, it's just a personal preference and probably 90% of users will get along just fine without it.
I may want to resize the the System Reserved partition which holds Winre.wim and put install.wim there.
But how will i manage to show install.wim file to REAGENTC.exe, that partition is not accessable from Windows.
