Windows 7: "sfc /scannow" an offline Win7 on hard disk from booted Win10 ?

"sfc /scannow" an offline Win7 on hard disk from booted Win10 ?

Assume a hard disk contains a possibly (partially) corrupted Windows 7.

I boot now a ToolsCD or USB flash drive with Windows 10.

When I open now a CmdPrompt and enter

sfc /scannow /offwindir=C:\Windows /offbootdir=C:\

then I cannot do this since the local, active, running WinOS is different from the investigated one.

Is there a workaround for that?

I can imagine that I can somehow put a windows 7.iso file onto the ToolsCD/USB flash drive and tell the "sfc" command to look
for the corresponding files inside this archive. Something like this:

sfc /scannow /offwindir=C:\Windows /offbootdir=C:\ /usewinosfilesfrom=X:\windows7.iso

Is this possible?

Hi Peter,

Assuming its the correct directory (C)
(unlikely as your W10 will occupy it, more likely D)


sfc /scannow /offbootdir=C:\ /offwindir=C:\windows

(additional \ and windows)

Hi Roy,

your command is the same as mine just with switch parameter sequence.
Since the order of parameters does not matter its the same command

Any "gotchas" when backleveling from Win10 to Win7?
I have a brand new HP ProBook 455 (A10-8700P CPU) that came with Win10. I would like to backlevel it to Win7 using a clean install (from DVD), including a repartition of the hard drive. (I've done clean installs before, including backleveling from Win8.1 to Win7, so this isn't my first rodeo.) ...
