Cannot check (C:) Drive but It says I need to do that to restore (I'm trying to restore however it say"The Disk OS (C:) has errors. Window has detected file system(Image above) corruption to OS (C:) You must check the disk for errors before it can be restored.)
And I do the check disk button but It says you cannot check while (C:) is in use.
Note: I can't disk check due to the (C:) Error, I can't even start up unless I do Safe Mode.
PS: It's a Dell, With Windows 7.
