Don't boot all the way to safe mode

Restart your computer. As the computer boots up, repeatedly hit the F8 key until the Advanced Boot Options appear. This menu allows you to boot to a command prompt without loading Windows.

Select “Safe Mode with Command Prompt.” The computer will continue booting and you will see a list of drivers being loaded. After they finish loading you will be presented with a command prompt.

Run chkdsk. Type “chkdsk” and press enter to run a check on the current drive without fixing any errors.
To run chkdsk and fix errors, type “chkdsk c:/f” Replace “c” with the drive letter you would like to fix.
To run chkdsk and fix errors, locate sectors and retrieve data, type “chkdsk c:/r” Replace “c” with the drive letter you would like to fix.
You may be prompted to restart if the drive is in use. If prompted, press Y to accept.
