Windows won't start/Startup repair won't work [solved]

It's solved I just post it in case it could help.

Yesterday I fully charged my laptop (XPS 17, Windows 10). I rarely do that. This morning I could not start it: blue screen of death
I ran a startup repair which faied: it says it could not repair and that the log file is E:\WINDOWS... (there is no E drive)

I ran several command like:

• bootrec.exe/scanos (it says: total identified installation0 )
• chkdsk : error detected in the upper file case (stage3)
• chkdsk c: /f (no error)
• chkdsk c: /r: no error
• sfc /scannow (tooks 5mn and says "windows resource protection could not perform the requested operation")

Finally I did unplug everything from the computer (eg. headset, USB, charger...), and it solved the problem. Might be a static electricity problem.

Going forward consider making free backup images.

Images can be restored in case there is / are:

malware
ransomware
corruption of the operating system
corruption of the drive file system
corruption of the registry
failure to boot
unexpected drive failure
etc.

(Acronis, Aoemi, EaseUS, Macrium, Paragon, etc.)

Macrium is widely used in Ten Forums:
