A regular command prompt (with admin privileges if UAC is turned on). Type cmd in the run box, then press enter. (See end of post for some methods to create admin privilege cmd prompt.
From there type
CHKDSK [volume[[path]filename]]] [/F] [/V] [/R] [/X] [/I] [/C] [/L[:size]] [/B]
volume Specifies the drive letter (followed by a colon),
mount point, or volume name.
filename FAT/FAT32 only: Specifies the files to check for fragmentation.
/F Fixes errors on the disk.
/V On FAT/FAT32: Displays the full path and name of every file
on the disk.
On NTFS: Displays cleanup messages if any.
/R Locates bad sectors and recovers readable information
(implies /F).
/L:size NTFS only: Changes the log file size to the specified number
of kilobytes. If size is not specified, displays current
size.
/X Forces the volume to dismount first if necessary.
All opened handles to the volume would then be invalid
(implies /F).
/I NTFS only: Performs a less vigorous check of index entries.
/C NTFS only: Skips checking of cycles within the folder
structure.
/B NTFS only: Re-evaluates bad clusters on the volume
(implies /R)
The /I or /C switch reduces the amount of time required to run Chkdsk by
skipping certain checks of the volume.

Take your computer for repair. ~ Try accessing The Check Disk function firstly. Even in Windows 10, the CHKDSK command is run via the Command Prompt, but we'll need to use administrative privileges to properly access it. To launch a Command Prompt as an Administrator, press the keyboard shortcut Windows Key + X to bring up the power users menu, then let go of those two keys and tap the A key. Alternatively, with the power users menu open you can use your mouse or trackpad to select the Command Prompt (Admin) option. Nowyou will be presented with a UAC window requesting permission to launch the Command Prompt as Administrator. Click Yes to proceed and you'll see a new Command Prompt window. You can verify that you've successfully granted the Command Prompt administrative privileges by ensuring that "Administrator: Command Prompt" is present in the window's title bar. From the Command Prompt, type this command WITHOUT The quotes ; "chkdsk" followed by a space, then the letter of the drive you wish to examine or repair. I suspect yours will be it's internal drive "C." Simply running the CHKDSK command in Win 10 will only display the disk's status, and won't fix any errors present. To tell CHKDSK command to fix the drive, we need to give it parameters. After your drive letter, type the following parameters separated by a space each: "/f /r /x". The "/f" parameter tells CHKDSK to fix any errors it finds; "/r" tells it to locate the bad sectors on the drive and recover readable information; "/x" forces the hard drive to dismount before the process starts. Please note that this can take quite a time to do all the processes so you must be patient.
DOS box
you have to use the command prompt(also called the DOS prompt by older users. You can find this by going to "start" , "programs" , "accessories" and "command prompt"
press the 'x' in the corner. Type in the word exit.
start -> Run -> regedit
Typing in "cls" without the quotes and hitting enter will clear the command prompt window (DOS window) and show you just the current prompt such as "C:". If you search for "dos commands" you should find some lists of things that are available when you are in the command prompt. But be aware that not all are active on all computers and some commands can delete files and do other things that you may not really want. -)
