Hi everyone
So today out of blue my computer stops working, restarts itself and the black screen shows up with massage "operating system not found"
Somehow I managed to run bios and it is recognising HDD but still nothing that I can do from here as it won't run windows at all. What do I do? Thanks everyone

Using the command prompt may fix your problem since it sounds like your boot files got corrupted.

To do this, if you cannot access your repair computer options:
Use the recovery disc or windows cd that came with your pc (if you still have it, then you can skip to opening command prompt)

Burn a bootable cd or usb with your version of windows on it. (requires another computer to boot into)
Boot from the disc or usb then access the repair computer options from the setup file
Open a command prompt.

Try this in the command prompt
Type in
Bootrec /fixmbr
Bootrec /fixboot
Bootrec /rebuildbcd

Reboot and see if this fixes it.
