If you can't boot normally, see if you can boot to Safe Mode and run chkdsk from there:
- Boot to Safe Mode by pressing the F8 key when the computer first starts booting, as soon as you see the manufacturers logo. Continue to press it every second or so until you get the Windows Advanced Options menu.
- Select Safe Mode using the arrow key on your keyboard and press Enter.
- Login as Administrator (no password unless you added one. If so, enter that password).
- Open My Computer.
- Right click on drive: and select Properties (drive: is your boot drive, usually C:)
- Click on the Tools tab then the Check now button.
- Check the Automatically fix File System errors box.
Alternatively, you can click on Start
, type chkdsk c: /r
and press Enter
For your boot drive (usually C:
), you will get a window that says the check could not be performed ....
Do you want to schedule this disk check to run the next time you restart the computer?
Click on Yes
Shutdown and reboot. Chkdsk will start. It can take an hour or more to run depending on the size of your hard drive.
Be patient and let it complete undisturbed.
