Solved SFC "Could not perform the requested operation"

[darts592]

Hello everyone,
In my computer, I try to run

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

from the recovery console.

However, after "Beginning system scan. This process will take some time.",
it almost immediately returns "Windows Resource Protection could not perform the requested operation.".

How can i fix this problem?

Hello darts,

You may not be using the correct drive letter for your Windows drive/partition. It's not always C: at boot.

Double check using METHOD TWO in the tutorial below to help verify what the drive letter is.

Hope this helps,

I have verified many times that the partition C is the one on which windows 7 is housed and the one which I need to repair.

In that case,

Perform a chkdsk /r command on the HDD to see if it finds any bad sectors and can fix them. Afterwards, try the SFC scan again.

I have run diskcheck and it finds 0 bad sectors. The sfc command is still unable to run.

Are you able to run the SFC scan from within Windows?

No. I was not able to boot into the partition in need of repair and it could not run from my other partition. I have decided to reinstall the broken partition.
