Repair the EFI Bootloader in Windows 8 diskpart not working

I have an HP ENVY 14-k074ca with win 8 on it. Two days ago it did update to win 8.1. After that it crashed and went into the infinite loop of automatic recovery. I THEN tried to use a win8 USB to solve the problem. of course auto recovery not working.

Refresh your system display : "the drive where windows is installed is locked. Unlock the drive and try again"

Also restore to factory setting found no image. When run diagnostic i got the error : 0xc0000098 error on boot/bcd

I used the command line tried :

bootrec /fixboot
bootrec /fixmbr
bootrec /rebuildmbr    

success but nothing happened it detect 0 installed window.

and here is the thing when i try

chkdisk

found bad on on-disk uppercase table

chkdsk /f

the type of file system is NTFS can not lock current drive

also

sfc /scannow display

windows resource protection could not start th repaire service

the last propose was diskpart but when I run it display the tool version but diskpart> prompet never appear.

can someone help me i really need the data on my PC and the programs installed on it.

There is a chance you're facing an HDD failure, but you can try to run the following commands from your Windows 8 USB media:

bootsect /nt60 ALL /force
bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd

Then restart.

If it doesn't solve your boot problem I strongly advise you to boot on some Windows PE based CD/USB media with a GUI (Hiren's boot CD for example) and connect an external HDD to try backuping your important files.
