4. On the right pane of the Start menu, click on Run as administrator and wait for the Command app to load
5. In the command app type: chkdsk /f /r and hit the ENTER key
6. After hitting the ENTER key, you will most likely be prompt with the following message:
a. Chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts? (Y/N)
7. This message is presented because we ran the chkdsk command on an actively used drive which is the C: drive in this case. This is the drive where the Windows operating system is installed and being run.
8. Type “y” and hit the ENTER key again.
9. The next message will be:
a. This volume will be checked the next time the system restarts
12. As declared by chkdsk in CMD in stage 9, chkdsk is about to perform a disk check and I’s asking if you wish to skip it.
13. Note that this is the last opportunity to safely abort chkdsk’s check before it performs it.
14. Note that this check takes quite a while to perform, especially in big mechanical hard drives
15. If you wish chkdsk to perform the check, do not press any key and wait for the timer to finish.
16. Chkdsk is now performing the disk check.
17. When it’s done it will resume booting into Windows.
18. Note that the ETA initials at the end of the sentence indicate the estimation time to completion of the scan
