Found information on this site to execute a DISM repair by specifying a source:

First downloaded MediaCreationTool_22H2.exe from Microsoft and created Windows_22H2.iso
Burned it to a DVD and mounted this DVD in DVD-drive of HP ProBook 450 G4

Then executed DISM /online /restoreHealth and specified Source: (F:-drive is DVD-drive)

PS C:\WINDOWS\system32> dism /online /cleanup-image /RestoreHealth /Source:F:\sources\install.esd

The process seemed stuck at approx. 62.3 % and after a while went to 100%
It did not seem to access the DVD - no spin up heard.

There is only a install.esd in the *.ISO image - no install.WIM

What am I doing wrong here?

What does the /Online parameter to DISM mean?
The active running OS or a reference to be Online on the Internet?

Any advice is welcome
