I tried fixmbr is working but others aren't I don't know why fixboot tells me access denied0xc0000098 error means startup windows files are damaged. I found this solution, no idea if its goona work.
Use Recovery environment -> advanced -> cmd and type those comands:
BOOTREC /SCANOS
BOOTREC /FIXMBR
BOOTREC /FIXBOOT
BOOTREC /REBUILDBCD
i tried but nothing works anyway I could boot the pc idk how but when I unplug the USB it's freezes is it possible to fix this while I can boot to the pc ?
