Question Does DISM command really delete any of my data or installed apps or my other drives data ?

Hi,
All it started with windows 8.1 restart instead of shutdown so I ran sfc /scannow. It found corrupt files and unable fix it. google search shows to run this below command to fix this corrupted files.
I read DISM command in Microsoft site but it says something beyond my English knowledge so better to ask experts from here.
all I want to know is running these command will delete any of my data or installed app or other drive data stored in my HDD ?
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth
Thanks

It shouldn't though my query ism, are you able to boot into Safe Mode? If so, backup all your critical data and then proceed to a clean install of the OS.

It only touches the Windows system files.

I'm able to boot in normal mode. so re-installing is the final solution to this issue ?

If you can boot into normal mode then what is your issue?
If it causes problems re install, if you don't have any problems just leave it.

And whether it does or does not (it doesn't), you should always have a good backup anyway.

What is the reason for this DISM and sfc?
Some "issue", correct?

Well...what happens if/when things get really bad. The drive dies, or you actually need to do a full OS reinstall.
Not everything is 'fixable in place'.
